Output
Connector: XLR
Signal: Balanced
Operating Level: +4dBu
Maximum O/P Level: +26dBu
Ext A/D IP
Connector: XLR/Jack
Signal: Balanced
Operating Level: +4dBu
Maximum IP Level: +22dBu=0dBFs
Int A/D Direct Input
Connector: TRS (Stereo) Jack
Signal: Balanced
Operating Level: +4dBu
Maximum IP Level: +22dBu=0dBFs
Inserting a jack breaks the connection of the A/D input
from the inernal signal path (fed by whatever is connected
to the mic, line or instrument inputs) and routes the signal
from the jack directly to the left channel of the A/D
converter (via the meter and limiter).
Comp Key IP
Connector: TRS (Stereo) Jack
Signal: Balanced
Operating Level: +4dBu
Maximum IP Level: +26dBu
Drives the sidechain of the compressor.
Dynamic Link
Connector: TRS (Stereo) Jack
Links two ISA 220 units, allowing control of the dynamics
sections of each from one unit, giving true stereo dynamics
control.
