CMX PA-4500RM – 4 Zone Remote Microphone
Professional 4-Zone Desktop Remote Paging Gooseneck Microphone for CMX PA-4500 Series Matrix Amplifiers with CAT6 Daisy-Chain Connectivity Up to 200m, Built-In Chime, All-Call Button & Direct 24V DC Bus Power
The CMX PA-4500RM is a professional 4-zone remote desktop paging gooseneck microphone engineered specifically for the CMX PA-4500 series matrix mixer amplifiers (including the PA-4120MX, PA-4240MX, PA-4350MX, and PA-4500MX). Designed for administrative desks, reception counters, security control rooms, and dispatch stations, the PA-4500RM enables operators to direct live voice paging to any of four discrete speaker zones or broadcast simultaneously across all zones via a dedicated ‘All-Call’ key. Operating over standard straight CAT6 network cabling up to 200 meters away from the host amplifier, up to 6 remote microphone stations can be cascaded hand-in-hand with configurable master/slave priority hierarchies set via rear dipswitches. Directly powered over the CAT6 bus by the host amplifier without requiring cumbersome local power bricks, and featuring a built-in pre-call alert chime, local microphone gain trim, and an auxiliary line input, the PA-4500RM delivers reliable, articulate commercial paging across hospitality, corporate, retail, and industrial facilities.
Ideal For
Core Engineering Features
Discrete 4-Zone & All-Call Paging Selection
Features four illuminated zone selection buttons plus an ‘All-Call’ button, allowing operators to direct live announcements selectively to individual areas or broadcast universally across all zones.
Long-Distance 200-Meter CAT6 Communication
Transmits uncompressed, high-intelligibility audio and control signals over standard straight CAT6 network cable up to 200 meters away from the central matrix amplifier.
Cascaded Hand-in-Hand Capacity (Up to 6 Units)
Equipped with dual RJ45 bus connectors (amplifier input and loop output) allowing up to 6 remote microphone stations to be daisy-chained together from a single amplifier connection.
Configurable Master & Slave Priority Dipswitches
Built-in rear hardware dipswitches allow installers to define distinct priority hierarchies among connected paging stations, ensuring management or security microphones take precedence.
Direct Bus Power (24V DC) from Amplifier
Draws operational power (24V DC) directly through the CAT6 bus cable from the host amplifier, eliminating the need for unsightly local power outlets or wall adapters.
Integrated Pre-Announcement Chime & LED Indicators
Includes a built-in musical chime tone to prepare listeners before live announcements, backed by comprehensive LED indicators for Power, Send (Transmission active), and System Busy.
Auxiliary Local Line Input & Microphone Gain Trim
Features an auxiliary audio input to inject local music or recorded announcements, along with a precision potentiometer for setting optimal speech volume levels.

Frequently Asked Questions
Which amplifiers are compatible with the CMX PA-4500RM remote microphone?
The PA-4500RM is engineered specifically to interface with the CMX PA-4500 series matrix mixer amplifiers (including models PA-4120MX, PA-4240MX, PA-4350MX, and PA-4500MX), communicating control and audio signals directly via CAT6 cabling.
How many PA-4500RM remote microphones can be connected to one amplifier?
Up to 6 remote microphones can be connected to a single PA-4500 series amplifier. They feature dual RJ45 ports allowing them to be daisy-chained (hand-in-hand) along a single CAT6 run up to 200 meters in length.
Does the PA-4500RM require a separate power supply adapter at the desk?
No. The microphone receives 24V DC power directly through the CAT6 network cable from the host amplifier, providing a clean, cable-free installation on reception counters and executive desks.
Can I configure one microphone to have higher priority over others?
Yes. Each PA-4500RM microphone includes rear dipswitches that allow system integrators to configure master and slave priority levels. If a master microphone (such as one at the security desk) initiates a call, it takes precedence over secondary stations.
Can I broadcast to all zones at the same time?
Yes. In addition to individual Zone 1 through Zone 4 push buttons, the PA-4500RM features a dedicated ‘All-Call’ button that instantly routes the microphone announcement to all four zones simultaneously.
