AA30-301 Expansion Panel Manual SM74 Rev. 4.10
All transmitters may be deselected by partially depressing any unselected transmitter
control.
When a transmitter is selected, the mic key and mic audio signals are automatically
directed to that transmitter.
A selected transmitter control bypasses the corresponding receiver control selector
switch (see section 3.3.2) to provide an auto-receive function.
3.3.2 Receiver Selection
The receiver control switches are four
push-on/push-off rotary switches that are used to
select receivers and adjust volumes.
3.3.2.1 Selection
When the receiver control switch is in the default depressed (in) position, the
corresponding receiver is deselected (off), and when the receiver control switch is in the
extended (out) position, the corresponding receiver is selected (on).
The default position for all receivers is deselected (in).
The auto-receive function automatically selects a receiver for audio when the
corresponding transmitter control is depressed, even if the receiver control is not in the
selected position.
Receiver controls are independent; any combination of receivers may be simultaneously
selected.
3.3.2.2 Volume
Control
The volume for each receiver can be adjusted by rotating the corresponding control.
The receiver volume is decreased to minimum at the full counterclockwise (ccw) stop,
and increased to maximum at the full clockwise (cw) stop.
If a receiver is activated by the Auto-receive function, the level is set by the current
receiver volume control, even if the control is deselected.
