Shure RPM53C/O-MDOT – Replacement Boom Arm for TH53, Cocoa, Microdot

Product Overview

The Shure RPM53C/O-MDOT is a genuine OEM replacement boom arm for the TwinPlex TH53 subminiature headset microphone in cocoa finish, terminating in a Microdot connector. Designed for theater, broadcast, and live speech professionals deploying the TH53C in cocoa for improved concealment on darker complexions and hair, this replacement part restores factory specification when a boom arm is damaged or worn. The Microdot connector is widely adopted across professional wireless bodypack transmitters from major manufacturers, providing broad system compatibility without requiring adapters in most production environments.

Product Description

The RPM53C/O-MDOT retains the TH53's clutch adjustment system for fast boom arm length and pitch repositioning with a simple quarter-turn knob, essential for rapid performer changeovers in live theater or broadcast. The cocoa finish reduces on-camera and on-stage visibility against darker skin tones and hair, consistent with professional concealment practice in performance environments. The Microdot connector provides compatibility across a wide range of wireless bodypack transmitters. The 1.6 mm cable retains dual redundant ground construction for additional RF shielding in wireless-dense environments. See the Shure RPM400LEMO TwinPlex Preamp if your system uses a LEMO3 interface.
