How are the signals metered on the Alpha Link units?
The metering section includes the Meters button, the AD and DA indicator LEDs and twenty four metering LEDs. These allow the level of the signals received via the analogue inputs or transmitted via the analogue outputs to be monitored.
Pressing the Meters button switches the monitoring mode between AD (the level of the signal received via the analogue inputs is monitored) and DA (the level of the signal transmitted via the analogue outputs is monitored).
For each analogue input or output channel, the signal level is represented by the state of the LED with the corresponding number.The LEDs respond to the signall evel as follows:
Up to 30dBFS: the LED is off.
From 30dBFS: the LED is green.
From 3.0dBFS: the LED is amber.
From 0.1dBFS: the LED is red.
