Optional Digital / Firewire card

This optional module has 2 FireWire ports, Wordclock sync IN and OUT and a 25-way D-type connector for AES Ins/Outs.

If this option is not present, there will be a blanking plate fitted instead, (as shown in the previous section), plus the Sample Rate leds & buttons on the front of the unit will not function.

The AES IN/OUT and Firewire ports are intelligent, in that if a Firewire connection is detected, then FireWire will be the digital interface.

If a Firewire connection is not detected, the unit will presume the audio is coming in via the AES IN/OUT 25-way D-type connector.

The expansion module the also has 4 DA/AD converters:

•AES signals going into AES IN/OUT (or Firewire if detected), these signals will also be output as analogue from LINE OUT of the 25 way D-sub connector.

•If INS is selected on a channel, the corresponding analogue input signal connected to INS IN of the 25 way D-sub connector, will be converted and output as AES signals from the AES IN/OUT (or Firewire if detected).

By default, the Post- gain amplified signal from the Mic/Line input will be routed to the A/D inputs.
