This completes the selection of two-device or four-device
operation and/or SRP mode. Close all open dialogue boxes
and windows.
When SRP mode is selected, a new control button appears in
the "Record" lines of the Antex Mixer. This is the "Mute" button.
The Mute button will only be present when the StudioCard and
Antex Mixer are set for SRP mode, and this can only occur in
either two-device or four-device operating mode.
The Mute button allows you to mute the feedthru audio (going
from the record device to the line outputs) while recording in
Simultaneous Record-Play (SRP) mode. When in non-SRP
mode, this control is not needed, as you can just turn down the
play half of the device.
