7. Program ON-OFF-INTRPT Switches: The program on-off-intrpt
switches are used to manually or automatically control program audio
feed into the intercom lines. The settings are as follows:
•
ON: The channel will receive program audio when the switch is set to
on. The audio level for each channel can be adjusted with the program
level trimpots.
• OFF: The channel will not receive program audio when the switch is
set to off.
• INTRPT: Pressing the talk button will interrupt the program when
this switch is set to intrpt.
Note: You can set this feature so the pressing the call button for a channel,
rather than the talk button, interrupts the program audio. See the section
“Resetting Program Interrupt Options” at the end of this chapter.
8. Program Level Controls: Adjust the program-level controls to set the
program audio level heard on the intercom. There are three program-level
controls. The program level knob to the left of the speaker on-off switch
adjusts the level of program heard in the headset or panel speaker.
The program levels heard on each intercom channel line can be individu-
ally adjusted, but this is intended to be a one-time setting made when the
MS-702 is set up. This is done using the screwdriver level adjustment
trimpots adjacent to the program on-off-intrpt switches on channels A and
B. Set the sidetone null controls and the program level knob fully counter-
clockwise when adjusting the individual channel program-level trimpots.
After the program-level trimpots are properly adjusted, use the procedure
listed in the Sidetone Controls section on this page to set the sidetone
level.
Note: Do not force the trimpots past their stop points. This will damage
them.
9. Party-line Link (A+B) Switch: When pressed, the party-line link (A+B)
button combines both intercom channels into one; for example, for
rehearsals. The party-line link button illuminates amber when on, and all
of the stations on the B channel will be moved onto the A intercom line.
This will allow communication between everyone on both channels at
once.
In this mode, the channel B controls and switches will be inactive. Since
the wiring for the B channel has been now added to the A channel, the
sidetone null control for channel A may require some readjustment.
10. Speaker ON/OFF Switch: The speaker on/off switch turns the front
panel speaker on or off. This switch does not affect whether the tone alert
is heard through the speaker. The speaker volume will automatically dip
whenever the panel or headset microphone is on.
11. Remote Mic Kill Switch: The remote mic kill (RMK) switch will turn off
the talk function of every beltpack on channels A and B. If the talk
functions of a large number of beltpacks have inadvertently been left
activated, incidental noise and talking can make it difficult or impossible
to communicate on the party-line intercom. The RMK switch can be
