4081 User Manual
Issue 3
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,
and 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 the 4081 will presume that FireWire will be
the digital interface, and not the AES.
If a Firewire connection is not detected, then the 4081 will presume the
audio is coming in via the AES IN/OUT 25-way D-type connector.
The optional expansion module has 4 DA/AD converters:
•
AES signals going into AES IN/OUT connector (or Firewire if
detected) will also be sent as analogue outputs from the LINE OUT of
the 25 way D-sub connector.
•
If INS is selected on a channel, then 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 also be
routed to the A/D inputs.
