RTS MCE325

Updated August 6, 2026

RTS MCE325 The MCE-325 is a 4-channel, programmable intercom station. It may be used as a headset station or with the addition of the MCS-325 Modular Speaker as a speaker station. It may be mounted in a console or equipment rack via optional mounting kits. The MCE-325 can be used with either 2-wire or 4-wire intercom lines, or a combination of both. In the labeling on the MCE-325, references to channels 1, 2, 3, and 4 indicate 2-wire lines; references to 4-wire A and 4-wire B indicate 4-wire lines. The MCE-325 can be interfaced to a variety of external devices including external program sources, 2-way radios, paging systems, and satellite circuits. Features: • Call signaling is accomplished using an inaudible (20kHz) signal to activate a call indicator LED. • Remote talk-off (mic kill) active, unattended remote station microphones may be deactivated by momentarily injecting an inaudible (24 kHz) signal into the corresponding intercom line. The MCE-325 can send and receive talk-off (mic kill) signals. • VOX circuit, the MCE-325 may be programmed for voice activation of the microphone. • Simple IFB program audio assigned to a channel is interrupted during talk. • The microphone preamplifier circuit contains a limiter, which helps to equalize voice levels. • Retains programming even when power is shut off. • External devices, such as 2-way radios, speaker mute relays, or paging systems may be activated through key outputs at the auxiliary connector on the rear panel. The key outputs may also be used to expand the simple IFB function, allowing any one (1) of a number of MCE-325 stations to interrupt the program source and talk on the line.
