RTS MCE-325 A4F
4-Channel User-Programmable Master Station with A4F Headphone Connector

OUR PART #  MCE325/A4F


RTS' MCE-325 is a four-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 two-wire or four-wire intercom lines, or a combination of both. In the labeling on the MCE-325, 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 MCE-325 can be interfaced to a variety of external devices including external program sources, two-way radios, paging systems, and satellite circuits.

NOTE: Shown above with A5F connector, thought it comes with an A4F connector.

Features:

  • 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 MCE-325 can send and receive “talk-off” 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.
  • 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 MCE-325 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.
  • Instantaneous Auto Reset (IAR), the newest technology in performance and safety, which uses a revolutionary new circuitry that dynamically monitors line fault conditions. Then, when the fault is removed, automatically brings individual power supply channels up.
