SPEAKER DIP FUNCTION:
Pressing either
talk
button will reduce the
output level of the speaker by a set amount to avoid feedback.
CALL BUTTONS
Each channel has its own
call
button. Pressing the call button at any time will
send a call signal on that channel regardless of the activation of the
talk
circuit
for that channel.
The
call
button for that channel will flash red while the
call
button is pressed
indicating the presence of a call signal on the line.
VOLUME CONTROLS
Each channel has a separate
volume
control for monitoring incoming audio.
Listening is always on and is not controlled by any logic. To listen to a
channel, turn up the appropriate control. To not listen to a channel, turn the
control completely off.
SIDETONE CONTROLS
Each channel has a
sidetone null
control. This control sets the amount of the
microphone that is heard in the earphone from that channel.
This control is a true hybrid null control and therefore is sensitive to changes
in line loading. For headphone use, it is best to find the
null
for a given
channel and then rotate the control clockwise to obtain the desired sidetone
level.
If the speaker and panel microphone are used together, providing a possible
acoustic feedback path, it will be necessary to use an almost complete null of
the sidetone control.
PROGRAM SEND LEVEL CONTROL FOR
CHANNEL A AND B
Both channels A and B have a
program send level
control that sets the volume
of program audio being sent to that channel when the program is activated.
SPEAKER ON/OFF SWITCH
The switch marked
speaker on/off
is used to turn the speaker on and off.
MIC SELECT SWITCH
The
mic select
switch enables the operator to select which microphone is
active.
