both the intercom channel and the US2000A headset or speaker (default setting).

off via the US2000A front panel programming. There is also an internal pro-
gram 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 ES4000A program inputs connector may be broken out to com-
mon 3-pin XLR audio cables using an optional XP-4PGM Breakout Panel.

nel audio input and output connections, as well as operating power when the
ES4000A is being powered from the intercom channels. Depending on the applica-

XP-ES4000 Breakout Panel. Examples of both connections are provided in the wir-
ing diagrams which follow. A channel output cable is supplied with each ES4000A.
