Instruction manual

RM-702 TWO-CHANNEL REMOTE STATION
2-14
CAUTION: All Clear-Com Intercom lines must be terminated. Care must be
taken not to fail to terminate or to “double”-terminate a line. All
unused intercom inputs must be terminated to keep the line drive
circuits stable. The RM-702 does not provide termination on the
intercom line.
PROGRAM INPUT
There are two different purposes for the program input: monitoring program in
the speaker and headphone, or feeding the Channel A and B intercom lines with
program material.
• Monitoring Program: To monitor program in the headphone or speaker:
• Connect the program source to the proper pins on the DB-15.
• Make sure the appropriate rear-panel program enable DIP switch is set to
the on position. For channel A, set the program enable A DIP switch to on.
For channel B, set the program enable B DIP switch to on.
• Use the large knob labeled “Program Volume,” located right next to the
speaker on/off switch, to set the appropriate program volume level. This
knob controls the program volume in the speaker/headphone.
• Set either the A or B potentiometer marked Program Level, located under
either the A or B channel’s volume knob, to the lowest setting. This control
affects the program volume going out onto the selected intercom line.
• Feeding Channel A or B Intercom Line: To feed the A or B channel with
program material:
• Connect the program source to the proper pins on the DB-15.
• Make sure the appropriate (A or B) rear-panel program enable DIP switch is
set to the on position. For channel A, set the program enable A DIP switch
to on. For channel B, set the program enable B DIP switch to on.
• Set the large knob, labeled “Program Volume,” located right next to the
speaker on/off switch, to the appropriate level. This knob controls the
program volume in the speaker/headphone.
• Set either the A or B potentiometer marked Program Level, located under
either the A or B channel’s volume knob, to the desired level. This control
affects the program audio level on the intercom line.
• If it is desired to interrupt this program feed, set the appropriate (A or B)
rear-panel Program Interrupt DIP switch to on and ensure that the Program
Enable DIP switch for the channel is set to off. When you do so, any time
you activate a call signal, the program audio is interrupted for the duration
of the call signal. There is an option to change this so that any time you
activate a talk signal, the program audio is interrupted for the duration of
the talk signal. See the earlier section in this chapter, “Re-setting Program
Interrupt Options,” for more information on setting this option.
