Each Alpha-Link SX, AX, or TX has the following IO:
- 24 line level analog IO
- 24 AES, ADAT, or Tascam digital, depending on model
- 64 MADI IO (one MADI link)
The above figures apply at up to 48 kHz.
At 88.2 or higher, IO count is halved for ADAT and MADI but maintained for AES/EBU.
MADI can operate in either 64 or 56 channel mode.
The Alpha-Link serves as a format converter between analog, digital, and MADI.
The later 1U Alpha-Link MX series has 16+4 or 4+16 line level analog IO.
The order of the analog and digital channels onto the MADI stream can be altered via the frontpanel diagnostic mode.
