About the Clear-Com RM-440
The Clear-Com RM-440 is a four-channel party-line intercom remote station compatible with all Clear-Com party-line intercoms. It accepts a wide range of dynamic headsets with a choice of connectors, and optional plug-in noise-cancelling gooseneck microphones are available in 9-inch and 18-inch lengths. An adjustable mic gain control and proximity-compensation circuitry maintain consistent voice levels across varying mouth-to-microphone distances. A variable speaker-dipping circuit helps eliminate feedback, while a sidetone control lets the operator adjust the level of their own voice in the headset. Separate volume controls for each channel allow a tailored audio mix, and all front-panel controls are programmable for a wide variety of applications. Unlike the MS-440, the RM-440 carries no internal power supply, circuit breaker or linking function, drawing power directly from the intercom line instead.
Clear-Com RM-440 — buyer FAQs
What is the Clear-Com RM-440 and what makes it a remote station rather than a main station?
The Clear-Com RM-440 is a four-channel party-line intercom remote station. It shares all the functions of the MS-440 except that it has no internal power supply, circuit breaker or linking function. Instead, it draws power directly from the intercom line, which means it can be placed anywhere along the line without needing a local AC connection.
Who makes the RM-440 and where does it sit in their intercom range?
The RM-440 is made by Clear-Com, a United States intercom and communications manufacturer with roots in San Francisco and a history spanning broadcast, live events, theatre and film. The RM-440 belongs to the 440 series, described as Clear-Com's most advanced party-line intercom system, sitting above simpler single-channel belt packs and offering four-channel operation with programmable front-panel controls.
What headset and microphone options does the RM-440 support?
The RM-440 accepts a wide range of dynamic headsets through a choice of headset connectors. Optional plug-in noise-cancelling gooseneck microphones are available in 9-inch and 18-inch lengths. An adjustable mic gain control and proximity-compensation circuitry keep voice levels consistent across varying mouth-to-microphone distances, and a sidetone control lets the operator adjust how much of their own voice they hear in the headset.
What environments is the second-hand Clear-Com RM-440 suited to?
The RM-440's programmable front-panel buttons and four-channel operation make it suitable for stage, studio and field production environments. Because it is powered from the intercom line rather than a local AC supply, it can be positioned flexibly across a venue or location without requiring a nearby power outlet, which is useful in temporary or remote production setups.
What should I check when buying a used RM-440?
Confirm how many channels are active and test all programmable front-panel buttons and individual channel volume controls. Check the headset connector type matches your existing headsets, and ask whether any gooseneck microphone is included. Verify the speaker-dipping and sidetone circuits function correctly.
