4081 User Manual Issue 2
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.
