Description

General

The MCE325 is a four-channel, programmable intercom station. It may be used as a headset station or, with the addition of the MCS325 Modular Speaker, as a speaker station. It may be mounted in a console or equipment rack via optional mounting kits.

The MCE325 can be used with either two-wire or four-wire intercom lines, or a combination of both. In this manual and in the labeling on the MCE325, references to channels 1, 2, 3, and 4 indicate two-wire lines; references to four-wire A and four-wire B indicate four-wire lines.

The MCE325 can be interfaced to a variety of external devices including external program sources, two-way radios, paging systems, and satellite circuits. Some typical applications are shown in Figure 1.2 through Figure 1.10.

Features

Features of the MCE325 include:

•Call Signaling: Call signaling is accomplished using an inaudible (20 kHz) signal to activate a call indicator LED.

•Remote “talk-off”: Active, unattended remote station microphones may be deactivated by momentarily injecting an inaudible (24 kHz) signal into the corresponding intercom line. The MCE325 can send and receive “talk-off” signals.

•VOX circuit: The MCE325 may be programmed for voice activation of the microphone.

•Simple IFB: Program audio assigned to a channel is interrupted during talk.

•External device keying: External devices, such as two-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 of a number of MCE325 stations to interrupt the program source and talk on the line.

•Microphone limiter: The microphone preamplifier circuit contains a limiter, which helps to equalize voice levels.

•Fully programmable: Retains programming even when power is shut off.
