11. Program Inputs Connector and Trimmers: Each intercom channel has its own
program input and level adjust trimmer. For each program input, there is an inter-
nal jumper which routes the program either to the intercom channel only, or to
both the intercom channel and the MS2000 headset or speaker (default setting).
Additionally, the program signal to the intercom channel may be turned on or
off via the MS2000 front panel programming. There is also an internal program
interrupt DIP switch which selects either automatic program interrupt when the
station operator activates a channel's talk key, or no program interrupt during
talk. The EMS4000 program inputs connector may be broken out to common
3-pin XLR audio cables using an optional XP-4PGM Breakout Panel.
12. Configuration Switches, Jumpers and Sidetone Controls (Figure
2
). These let
you customize the operation of the EMS4000 to match your intercom system re-
quirements. See “Configuration Pre-check”, page
7
, for details.
