Introduction to SSL 12

Congratulations on purchasing your SSL 12 USB audio interface. A whole world of recording, writing and production awaits you! We know you’re probably keen to get up-and-running, so this User Guide is set out to be as informative and useful as possible. It should provide you with a solid reference for how to get the best out of your SSL 12. If you get stuck, don’t worry, the support section of our website is full of useful resources to get you going again.

 

Overview

What is SSL 12?

SSL 12 is a USB bus-powered audio interface that enables you to get studio-quality audio into and out of your computer with minimal fuss and maximum creativity. On Mac, it's class-compliant - this means that you don't need to install any software audio drivers. On Windows, you'll need to install our SSL USB Audio ASIO/WDM driver, which you can download from our website or via the HOME page of the SSL 360° software - see the Quick-Start section of this guide for more information on getting up and running.

SSL 12's capabilities are further extended with the power of SSL 360°; an application hosted on your computer where the powerful SSL 12 Mixer page allows for super low latency (sub 1 ms) headphone mixes, flexible loopback functionality and customisation of the 3 user-assignable switches on the front panel. See the SSL 360° section for more information.

Getting Started

Unpacking

The unit has been carefully packed and inside the box you will find the following items:

  • SSL 12

  • Quickstart Guide

  • Safety Guide

  • 1.5m 'C' to 'C' USB Cable

  • USB 'C' to 'A' adapter 

 

USB Cables & Power

Please use the provided USB cable to connect the SSL 12 to your computer. The connector on the rear of SSL 12 is a 'C' type. The type of USB port you have available on your computer will determine if the USB C to A adapter is required. Newer computers may have 'C' ports, whereas older computers may have 'A'.

SSL 12 is powered entirely from the computer's USB 3.0-bus power and therefore requires no external power supply. When the unit is receiving power correctly, the green USB LED will light a steady green colour. SSL 12’s power is based on the USB 3.0 specification (900mA) so ensure you are connected to a USB 3 port and not a USB 2 port.

For best stability and performance, we recommend using the included USB cable & adapter if required. It should be possible to use a longer cable, but your mileage may vary depending on the quality of the cable, as cables with lower quality conductors tend to drop more voltage.

 

USB Hubs

Wherever possible, it is best to connect SSL 12 directly to a spare USB 3.0 port on your computer. This will give you the stability of an uninterrupted supply of USB power. However, if you do need to connect via a USB 3.0 compliant hub, then it is recommended that you choose one of high enough quality to provide reliable performance - not all USB hubs were created equally. 

 

Safety Notices

Please read the Important Safety Notice document included as a printed document shipped with your SSL 12 interface.

Selecting SSL 12 As Your DAW's Audio Device 

If you have followed the Quick-Start / Installation section then you are ready to open up your favourite DAW and start creating. You can of course use any DAW that supports Core Audio on Mac or ASIO/WDM on Windows.

No matter which DAW you are using, you need to ensure that SSL 12 is selected as your audio device in the audio preferences/ playback settings. Below is an example in Pro Tools. If you are unsure, please refer to your DAW's User Guide to see where these options can be found.

Pro Tools 

Screenshot 2022-06-21 at 11.38.39.png

Open up Pro Tools and go to the 'Setup' menu and choose 'Playback Engine...'. Make sure that SSL 12 is selected as the 'Playback Engine' and that 'Default Output' is Output 1-2 because these are the outputs that will be connected to your monitors.

Note: On Windows, ensure that 'Playback Engine' is set to 'SSL 12 ASIO' for the best possible performance.

 

Front Panel Controls

Input Channels

SSL 12 Channel Labled.png

 

This section describes the controls for Channel 1. The controls for Channels 2-4 are exactly the same.

1. +48V

This switch enables phantom power on the combo XLR connector, which will be sent down the XLR microphone cable to the microphone. When engaging/disengaging +48V, the LED blinks a couple of times and the audio is temporarily muted to avoid any unwanted audio clicks/pops. Phantom power is required when using Condenser microphones or certain active Ribbon mics. Dynamic or Passive Ribbon microphones do not require phantom power to operate, and in some cases can cause damage to the microphone. If in doubt, make sure +48V is off before plugging in any microphone and consulting the user manual from the manufacturer to ensure correct operation

2. LINE

This switch changes the source of the channel input to be from the balanced Line input. Connect line-level sources (such as keyboards and synth modules) using a TRS Jack cable into an input on the rear panel. The LINE input bypasses the pre-amp section, making it ideal to connect the output of an external preamp to if you so wish. When operating in LINE mode, the GAIN control provides up to 17.5 dB of clean gain.

3. HI-PASS FILTER

This switch engages the Hi-Pass Filter with a cut off frequency at 75Hz with a 18dB/Octave slope. This is ideal for removing unwanted low-end frequencies from an input signal and cleaning up unnecessary rumble. This is suitable for sources such as Vocals or Guitars. 

4. LED METERING

5 LEDs show the level at which your signal is being recorded into the computer. It is good practice to aim for the '-20' mark (the third green meter point) when recording. Occasionally going into '-10' is fine. If your signal is hitting '0' (top red LED), that means it is clipping, so you'll need to lower the GAIN control or output from your instrument. Scale markings are in dBFS.

5. GAIN

This control adjusts the pre-amp gain applied to your microphone, line-level or instrument. Adjust this control so that your source is lighting all 3 green LEDs most of the time whilst you are singing/playing your instrument. This will give you a healthy recording level into the computer.

6. LEGACY 4K - ANALOGUE ENHANCEMENT EFFECT

Engaging this switch allows you to add some extra analogue 'magic' to your input when you need it. It injects a combination of high-frequency EQ-boost, together with some finely tuned harmonic distortion to help enhance sounds. We have found it to be particularly pleasant on sources such as vocals and acoustic guitar. This enhancement effect is created completely in the analogue domain and is inspired by the kind of extra character the legendary SSL 4000-series console (often referred to as '4K') could add to a recording. The 4K was renowned for many things, including a distinctive 'forward', yet musical-sounding EQ, as well as its ability to impart a certain analogue 'mojo'. You will find that most sources become more exciting when the 4K switch is engaged!

 

 

Monitor Controls

SSL 12 Monitor Section Labled.png

1. GREEN USB LED

Illuminates solid green to indicate that the unit is successfully receiving power over USB.

2. MONITOR LEVEL (Large Blue Control)
The MONITOR LEVEL directly affects the level sent out of OUTPUTS 1 (Left) and 2 (Right) to your monitors. Turn the knob to make the volume louder. Please note the MONITOR LEVEL goes to 11 because it's one louder.

Note that if ALT is engaged, Monitors connected to OUTPUTS 3 & 4 will also be controlled via the Monitor Level Control. 

3. PHONES A & B
These controls each set the level for the PHONES A & B headphones output.

4. CUT

This button mutes the Monitor Output Signal

5. ALT 

Switches the Monitor Bus to an alternative set of monitor speakers that you have connected to OUTPUTS 3&4. To do this ALT SPK ENABLE must be active in SSL 360°.  

6. TALK

This button engages the on-board Talkback mic. The signal can be routed to any combination of Headphones A, Headphones B and Line 3-4 (providing Line 3-4 is not being used as ALT monitors) in the SSL 12 Mixer page of SSL 360°. The Talkback Mic is located to the left of the green USB light.

Please Note: Interface buttons annotated as 4, 5 & 6 in the description are also user-assignable using SSL 360° but they come defaulted to the silkscreened functions (CUT, ALT, TALK) on the front panel.

Front Panel Connections

SSL 12 Front Panel v3-15.png

1 . INSTRUMENT INPUTS

INST 1 & INST 2 are the HI-Z Instrument inputs that allow high impedance sources such as Guitars & Basses to be recorded without the need for an external D.I. Plugging into an Instrument input will automatically over-ride the Mic/Line input on the rear.

2. HEADPHONE OUTPUTS

PHONES A & B allow for two sets of headphones to be connected, both of which can be configured to allow independent mixes for artist and engineer. The master output levels are set by the PHONES A and PHONES B controls on the front panel.

 

Rear Panel Connections

SSL12 Rear Connections Labled.png

1 . POWER

The power button toggles power on/off to the unit.

2. USB

USB 'C' Type Connector - connect SSL 12 to your computer using the included cable.

3. ADAT IN

The ADAT IN - a further 8 input channels to be added to the interface at 48 kHz, 4 channels at 96 kHz, and 2 channels at 192 kHz, allowing expansion to enable larger recording projects.  

4. MIDI IN & OUT

The MIDI (DIN) IN & OUT allow the SSL 12 to be used as a MIDI interface. MIDI IN will receive MIDI signals from keyboards or controllers & MIDI OUT allows MIDI information to be sent out to trigger Synths, Drum machines or any MIDI controllable equipment you have available.  

5. OUTPUTS

1/4" TRS Jack Output Sockets

Outputs 1 & 2 are primarily to be used for your main monitors and the physical volume is controlled by the Monitor Knob on the front of the Interface. Outputs 3 & 4 can be set up as a secondary ALT pair of monitors (switchable to be controlled by the Monitor Knob when the ALT button is engaged).

All Outputs (including headphone outputs as previously described) are also DC-coupled and able to send +/-5v signal to allow CV control to Semi & Modular Synths, Eurorack and CV-enabled outboard FX. 

Please Note: More information is available in the CV Control via Ableton® Live CV Tools section in this User Guide.

 A few things to be aware of when using the DC-coupled outputs: 

  • When using output 1-2 for CV output, remember the Monitor Control Knob is still affecting the signal. Some experimentation on finding the best level for your connected CV controlled synth/FX unit may be required.
  • Meters in the 360° Mixer are DC-coupled hence you can still expect them to work and show a DC signal. 

6. INPUTS

Combo XLR / 1/4" Jack Input Sockets

The 4 rear combo jacks accept Mic-level inputs (on XLR) and Line-level inputs (on TRS).  Hi-Z inputs for Channels 1 & 2 are located at the lower front of the interface and plugging into these will over-ride any Mic/Line rear panel inputs.

 Inputs - Analogue & Digital

SSL 12 Inputs_360 Inputs.png

1. Meters

The meters indicate the incoming signal level to the channel. If the meter turns red then it demonstrates the the channel has clipped. Click on the meter to clear the clip indication.

The +48V, LINE & HI-PASS functions can be controlled from either the hardware or SSL 12 software mixer.

2. Headphone Sends

This is where you can create independent mixes for HP A, HP B and Line 3-4 Outputs.

  • The Green Knob controls the set level for each Mix Bus (HP A, HP B & Outputs 3-4)
  • MUTE button mutes the send and illuminates red when activated.
  • The Pan control allows you to determine the pan position for that send. The PAN button must first be engaged.
    • If PAN is not engaged, then the send follows the main monitor bus Pan control in the fader section.

Tips:

Shift + Mouse Click sets a send to 0 dB.

Alt + Mouse Click (Mac) or Option+Click (Windows) sets a send to Off.

 

3. Line 3-4 Sends

Similar to the headphone sends, the Line 3-4 sends allow the signal to be routed to Outputs 3-4. When the output channel is stereo linked, a single set of controls for Pan, Level and Mute are controllable.

When the output channel is split into dual-mono, independent level controls appear, one for Output 3 and one for Output 4.

4. Scribble Strips

These are the text boxes on each channel identifying its input/output type and number order as default. These text boxes are editable, allowing each channel in the 360° mixer to be renamed by the user.

To re-name the Scribble Strip on the channel, simply double-click on the text box and type your preferred name.

5. Pan

The Pan control determines the position of the signal in the Monitor Bus stereo image. 

6. Faders 

The Fader section of the mixer allows control of the signal going out to the Monitor Bus & consists of 4 control parameters.

  • Pan Knob as previously described.
  • Solo button, soloing the channel in the Monitor Bus. This illuminates yellow when activated.
  • Cut button mutes the channel to the Monitor Bus. This illuminates red when activated.
  • Fader control the level, with a range from +12dB to -Infinite dB being sent to the Monitor Bus.

Tip:

Shift + Mouse Click sets the fader to 0 dB. Alt + Mouse Click also sets the fader to 0 dB.

 

7. Stereo Link 

Clicking on either 'O', two sequential channels can be stereo linked and will convert to a single fader stereo channel. When activated this 'O' will change to a green linked symbol as shown below:   

 

Screenshot 2022-08-04 at 10.29.31.png

Note: These controls affect only the playback of the signal via the Monitor Bus, and won't affect the signals recorded into your DAW.

 

Talkback

SSL 12 360° Talkback-16.png

Routing Sections HP A Highlighted as an example
In the same way as the Input channels, the TALKBACK channel can be routed to the Headphones & Line Output 3&4.
  1. The PAN button when illuminated engages the send's Pan.
  2. Pan Knob allows you to determine the pan position for that mix being sent to the Aux Bus. 
  3. The Green Knob controls the set level for each Aux Bus (HP A, HP B & Outputs 3-4) from +12dB to -Inf dB. 
  4. MUTE button mutes the send and illuminates red when activated.
This layout is identical for Headphones B & Line Out 3-4

5. Scribble Strip
This text box identifies the TALKBACK channel and is named as default. This text box is also editable, allowing it to be renamed by the user.

6. TALKBACK ENGAGE BUTTON
When illuminated green, the built-in TALKBACK mic will send the signal to the routed aux buss(es) (HP A, HP B & LINE 3-4). This can also be controlled by physically engaging the TALKBACK button on the SSL 12 Interface, or via the SSL 360° TALK software button (if assigned).

7.  FADER

The red capped fader sets the master output level of the TALKBACK signal. The Fader ranges from +12dB & -Inf dB. 

8. NO OUTPUT TO MASTER

The text at the bottom of the TALKBACK channel is a reminder that the TALKBACK signal is not sent to the MONITOR  BUS & can only be routed via the aux sends.

 

Digital Inputs

The 8 channels of Digital Inputs are provided by the optical ADAT IN port at the rear of the interface, accepting 8 channels at 44.1/48 kHz, 4 Channels at 88.2/96 kHz and 2 channels at 176.4/192 kHz.

The Digital Inputs provide no gain controls. Gains should be set on the external ADAT device.

Routing to the HP A, HP B & LINE 3-4 is identical to the Analogue Input Channels. 

 

Playback Returns

The 4x Stereo Playback Return channels allow separate stereo signals to be sent out of your DAW or other programs with assignable audio outputs, into the SSL 12 Mixer as inputs.

At the top of the channel next to the meters, the 'Direct' button allows each stereo Playback Return to bypass the SSL 12 Mixer's Routing Matrix and instead the signal is sent directly to the corresponding Aux/Bus Master.

SSL 12 Playback Reterns Direct Out-18-18.png

In the above diagram, Playback 7-8 is highlighted in Blue to distinguish the difference between engaged & disengaged Direct Buttons. 

 

1. DIRECT MON L-R

Engaging the DIRECT button will send the DAW Mon L/R outputs directly to the main Monitor Bus (OUT 1-2), bypassing the Routing Matrix.

2. DIRECT LINE 3-4

Engaging the DIRECT button will send the DAW 3-4 outputs directly to Line 3-4 Aux Master (OUT 3-4), bypassing the Routing Matrix.

3. DIRECT HP A

Engaging the DIRECT button will send the DAW 5-6 outputs directly to Headphone A Aux Master (OUT 5-6), bypassing the Routing Matrix.

4. DIRECT HP B

On Playback 7-8, engaging the DIRECT button will send the DAW 7-8 outputs directly to Headphone B Aux Master (OUT 7-8), bypassing the Routing Matrix.

5. ROUTING MATRIX

When the DIRECT Button is disengaged, the signals can be routed to the HP A, HP B & Line 3-4 from the SSL Mixer. As with the Input Channels, sends to the aux busses are controlled via the HP A, HP B & LINE 3-4 Send Level Knobs, with Pan, and muting button also accessible. 

6. SCRIBBLE STRIP

This text box identifies the Playback Return Channel and is named as displayed by default. The text box is editable, allowing it to be renamed by the user.

FADER

The fader controls the level sent to the Monitor Bus for each Playback Return Channel (providing DIRECT is disengaged), as well as providing SOLO, CUT & PAN functionality.     

 

Below is a visual illustration of DIRECT MODE. For simplicity, the illustration shows all Playback Returns with DIRECT Enabled (left-hand side) and all Playback Returns with DIRECT Disabled (right-hand side). Of course, you have the ability to toggle the DIRECT mode on/off for each Stereo Playback Return Channel.

 

Direct Mode Illustration.png

 

AUX Masters

The Aux Masters section of the Mixer View consists of both Headphones A, Headphones B & Line Out 3&4 aux master outputs.

Headphone Outputs

Each Headphone Output consists of a large Signal Metering section with a resolution from 0dB down to -60dB. 

 

Screenshot 2022-07-14 at 09.49.17.png

 

Below are details of the Fader section with the following parameters:

360° HP Outs-12-12.png

1. SENDS POST

When selected, send levels to the aux busses from the channels will be Post Fader level. 

2. FOLLOW MIX 1-2 

Over-rides the aux master so that it follows the Monitor Bus mix, providing an easy way to send what you are listening to on the Monitor Bus (through your monitor speakers) to the Headphones.

3. AFL

Short for 'After Fade Listen' allows the user to monitor the Aux Mix on the Main Outputs; ideal for quickly listening to the Artist's headphone mix.

4. CUT

Mutes the signal output of the HP Aux channel

5. MONO

Switches the output to Mono, summing both L&R signals together. 

6. Fader

Sets the master level for the HP Bus. Remember this is pre physical gain control on the SSL 12 front panel.

 

Line Output 3-4 Master

The Line 3&4 aux master has all the same parameter controls as the Headphones aux masters, but with the addition of the Channel linking button at the very bottom of the fader section.

SSL 12 Line 3-4 Stereo Link-19.png

When linked, the button glows green and represents Stereo Operation

 

  Screenshot 2022-06-29 at 12.36.04.png

Unlinked

. When unlinked, this will configure Line 3 & 4 as independent mono busses.

 

Screenshot 2022-06-29 at 12.31.05.png     Screenshot 2022-06-29 at 12.31.34.png

Left: Sends when Line 3-4 is linked , Right: Sends when Line 3-4 are unlinked.

When unlinked all input channels in the SSL 12 mixer will change their Line 3&4 sends to individual levels & mutes. If already set as a send to 3&4, the levels already set will be maintained in Mono between each channel. 

Within the SSL 12 360° Mixer, the signal sent to each Headphone Mix can be derived from any Input Channel or Playback Return or can mirror the main output mix by implementing the 'Follow Mix 1-2' button on the HP Channel in the Mixer.

 

MASTER OUT

This is the MONITOR BUS feeding your monitors via OUTPUTS 1-2 (or ALT OUTPUTS 3-4)

The MASTER FADER level will control the output volume signal, pre the physical Monitor Level Control on the SSL 12 Interface. 

MONITORING

This section of the Mixer pertains to the control of your SSL 12's range of comprehensive monitoring features. 

SSL 12 360° Mixer Monitoring-08.png

1. DIM

The DIM button will engage a level attenuation set by the DIM LEVEL ()

2. CUT

Cuts the output to the monitors.

3. MONO

This will sum the Left & Right channel signals of the Master Out together and provide a MONO output signal to the Main Outputs. 

4. POLARITY INVERT

This will invert the left side signal, allowing assessment of the phase relationship between the left & right signal. 

5. ALT SPEAKER ENABLE

This function allows you to connect a second set of monitors to Line Outputs 3-4. When ALT SPK is enabled, the MONITOR LEVEL will also affect the output signal level to Outputs 3&4 when ALT is engaged.  

6. ALT

With ALT SPK ENABLE (5) engaged, engaging the ALT button will transfer the MASTER BUS signal to Outputs 3&4

7. DIM LEVEL

The DIM LEVEL control adjusts the level of attenuation provided when the DIM (1) button is engaged. This allows up to -60dB of attenuation when fully tuned counter-clockwise.

8. ALT SPEAKER TRIM

The ALT SPKR TRIM knob allows gain adjustment to offset the output level sent to the ALT monitors connected to Outputs 3&4.  This allows the levels to be adjusted between the Main Monitors and Alt Monitors so the Monitor Control level doesn't need to be changed when A/Bing between two different sets of speakers for a more accurate comparison. 

 

SETTINGS

Screenshot 2022-06-30 at 09.34.39.png

In the bottom-right of the SSL 12 Mixer, you can access the Settings panel, which contains configuration options for the Headphone outputs and also Peak metering.

 

HEADPHONE OUTPUTS MODES

The HP outputs can operate in one of 2 modes:

  • Headphones Mode
  • Line Output Mode 

Headphones Mode Options

When operating in Headphones Mode, you can choose between 3 different options:

  • Standard - The default setting and is suitable for a wide range of headphones.
  • High Sensitivity - This is most applicable for use with certain In-Ear Monitors (IEMs) or headphones that have especially high sensitivity (expressed in dB/mW). Typically, headphones that specify their performance at 100 dB/mW or higher.
  • High Impedance - This setting is ideal for High Impedance headphones which require greater voltage drive to produce the expected output level. Typically, headphones with an impedance of 250 Ohms or greater will benefit from this setting.

Beware: Always make sure BEFORE you switch your headphone output to High Impedance, to turn the front panel level control down to avoid accidentally overloading your headphones if you are unsure of what sensitivity they are.

 

Line Output Mode Options

HP A and HP B can be switched into Line Output Mode. This allows you to use them as additional mono line outputs, instead of headphone outputs.

By default they are balanced but you can make them unbalanced by click the Unbalanced box.

Please beware when switching the output setting between Balanced & Unbalanced to be aware of the cables being used and the destination of the signal as not to introduce noise or distortion into the circuit. 

 

METERS PEAK HOLD

Determines how long the peak hold segment of the SSL meters hold for.

  • No Peak Hold
  • Hold for 3 Seconds
  • Hold Until Cleared

I/O MODE

You can put SSL 12 into I/O Mode by engaging the tickbox in the upper-left corner of the SSL 12 Mixer.

Screenshot 2022-06-29 at 10.47.06.png

I/O Mode bypasses the SSL 12 Mixer's routing matrix and fixes the routing as shown in the table below:

Screenshot 2022-06-29 at 10.03.42.png

I/O Mode can be used for different purposes:

  • To simplify the operation of the unit when you do not need the full flexibility that the SSL 12 Mixer offers.
  • It allows SSL 12's outputs to operate at 176.4 or 192 kHz, instead of downsampling them.
    • When I/O Mode is not engaged (SSL 12 Mixer is active) and you are operating at sample rates of 176.4 or 192 kHz, SSL 12's outputs are automatically downsampled to 88.2 or 96 kHz in order to preserve the full mixing capability of the mixer. Other audio interfaces typically limit mixer capability in the same scenario. 

So if you want end-to-end 176.4 or 192 kHz performance, then I/O Mode is a useful option.

CONTROL

The Control section displays key information in setting up your Interface ready for working within your DAW.

 

Screenshot 2022-08-17 at 13.33.32.png  

1. SAMPLE RATE

The drop-down menu allows the user to select the Sample Rate that the SSL 12 Interface will operate at. The selection allows for 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz & 192 kHz. Note, that when any DAW is opened, SSL 12 will follow the DAW's sample rate setting.

2. CLOCK

The Clock source menu allows the change between INTERNAL clocking or ADAT.

When using an external ADAT unit connected to the SSL 12, select the source to ADAT, allowing the ADAT-connected device to act as the clocking source (set the ADAT device to Internal). 

3. LOOPBACK SOURCE

This option allows you to record USB audio back into your DAW. This is especially useful for recording audio from other applications such as Youtube.

Screenshot 2022-06-30 at 10.50.10.png

To set this up, simply select the LOOPBACK SOURCE channel you wish to record from the drop-down menu (for example Playback 1-2 to record the output of a media player), then in your DAW, select the input channel as Loopback as shown below and record the audio as you would with any other input channel. Be sure to mute the recording channel in your DAW to avoid creating a feedback loop!

How-To / Application Examples

Connections Overview

The diagram below illustrates where the various elements of your studio connect to SSL 12 on the front panel.

SSL 12 Front Connections-13.png

This diagram shows the following:

  • An E Guitar/Bass plugged into INST 1, using a TS Jack Instrument cable. 

  • Two pairs of Headphones each connecting directly to the Headphone Outputs HP A & HP B

The below example visually details some likely uses for all the potential connections available on the rear panel of the SSL 12 Interface. 

Artboard 31.png

This diagram shows the following:

  • A microphone plugged into INPUT 1, using an XLR cable

  • A Stereo Synthesiser plugged into INPUT 3&4, using jack cables

  • Monitor speakers plugged into OUTPUT 1 (Left) and OUTPUT 2 (Right), using TRS jack cables (balanced cables)

  • A jack cable sending DC (+/-5V) out of OUTPUT 3 signal to the Synthesiser to control CV parameters.

  • MIDI OUT to trigger a Drum Machine
  • MIDI IN from a MIDI Control Keyboard
  • ADAT IN from an ADAT-enabled Preamp rack feeding 8x Channels of INPUT signal to the DIGITAL IN Channels of the SSL 12 360° Mixer
  • USB cable connecting SSL 12 to the computer

 

CV Control via Ableton® Live CV Tools 

All Outputs on the SSL 12 are DC-coupled (1, 2, 3, 4 and Headphone A and Headphone B) and able to send +/-5v signal to allow CV control to Semi & Modular Synths, Eurorack and CV-enabled outboard FX. 

When using DC-coupled outputs there are a few things to keep in mind: 

  • When using Outputs 1-4 for CV Control, if you are using mono jack cables (TS to TS) to connect to your CV-controlled equipment, it is recommended to apply a -10 dB level trim (which can be done in the DAW or via the Aux Masters/Master Output fader(s) in SSL 360°. We've found that this results in a more reliable calibration process with Ableton's CV Tools (achieving 1V/oct).
    • Alternatively, when using Outputs 1-4 for CV Control, you can use 'Insert cables' (TRS to 2 x TS jacks), with the TRS connected to the SSL 12 output(s), and the Send jack cable plugged into the CV-controlled synth/FX unit. In this scenario a -10 dB level trim may not be required.
  • When using Outputs 5-6 and 7-8 for CV Control (HP A and HP B), be careful to first unplug any attached headphones from the front panel outputs.
    • When using these outputs with for CV control, we found that using High Impedance Headphones Mode or Line Output Mode with unbalanced ticked generally provided the most reliable results.
    • Remember Headphone level knobs are still affecting the signal and some experimentation may be required to find the optimal level required for your connected equipment.

SSL 12 DC-Coupled Outputs

The SSL 12 Interface allows the user to send out a DC Signal from any output on the interface. This allows CV-enabled equipment to receive the signal to control parameters.  

What is CV?

CV is an abbreviation of "Control Voltage"; an analogue method of controlling synthesizers, drum machines and other similar equipment.

What are CV Tools?

CV Tools is a free pack of CV-enabled instruments, synchronisation tools, and modulation utilities that enable users to seamlessly integrate Ableton Live with various devices in the Eurorack format or Modular Synthesisers & Analog effects units. 

Setting Up Ableton Live CV Tools 

Screenshot 2022-07-01 at 15.33.24.png

  • Open your Ableton Live session
  • First set up a new Audio Track that you'll use to send out the CV Signal.
  • Then insert onto the Audio track a CV Utilities Plug-In from the packs menu.
  • Once the CV Utility Plug-In is Open, set the CV To to your designated Output. In this example we've set this to Output 4 from the SSL 12
  • Set up a second Audio track with the input signal from the Effect/Instrument and record arm to monitor the input back into Ableton Live.  
  • Now using the CV Value knob on the CV Control channel, you can automate the CV signal sent out of Ableton to your External Instrument/FX unit. This can then be mapped to a MIDI controller to control in realtime, or record the Automation into your session. 
  • Now you can record the audio back into your Ableton Session, or other DAW you may be using to record your Audio back onto your system. 
  • Please note that multiple CV Utility plugs can be set up when using the SSL 12 as EVERY PHYSICAL OUTPUT is able to send DC signal for CV Control. Therefore you can use up to 8 CV control signals at any one time using CV Tools and an SSL 12

Requirements for CV Tools 

 

Best Practices & Safety

  • Never send CV directly to your speakers (direct voltage can cause damage to your speakers).
  • The CV Instrument device is only capable of calibrating oscillators that use bipolar voltage (+/-5V) for 1v/oct. tuning.  However, some digital oscillator modules exclusively use unipolar signals (+5V or above) for tuning.  As a result, CV Tools will be incompatible with these modules.  If you are unsure whether this applies to the modules in your system, please consult the user manual for the device.
  • Remember - Eurorack signals are up to 5x louder than line-level audio! Before connecting your modular system to a digital audio interface, be sure to reduce the signal down to line-level using a dedicated output module.

 

SSL USB Control Panel (Windows Only)

If you're working on Windows and have installed the USB Audio Driver required to make the unit operational, you will have noticed that as part of the installation the SSL USB Control Panel will be installed onto your computer. This Control Panel will report details such as what Sample Rate and Buffer Size your SSL 12 is running at. Please note that both Sample Rate and Buffer size will be taken control of by your DAW when it is opened.

 

Safe Mode

One aspect you can control from the SSL USB Control Panel is the tickbox for Safe Mode on the 'Buffer Settings' tab. Safe mode defaults to ticked but can be unticked. Unticking Safe Mode will reduce the overall Output Latency of the device, which may be useful if you are looking to achieve the lowest possible roundtrip latency in your recording. However, unticking this may cause unexpected audio clicks/pops if your system is under strain.
