Shure RPM53T/O-MDOT – Replacement Boom Arm for TH53, Tan, Microdot
Product Overview
The Shure RPM53T/O-MDOT is a complete replacement boom arm and cable assembly for the TH53 TwinPlex omnidirectional headset in tan, terminated with a Microdot connector. Designed for theater, broadcast, and commercial live event production, this OEM replacement part restores a worn or damaged TH53 to full operating condition without replacing the entire headset. The Microdot termination is compatible with a wide range of professional wireless bodypack transmitters via standard adapters, making it a practical choice for integrators managing multi-transmitter wireless systems in house of worship, auditorium, and corporate environments.
Product Description
The RPM53T/O-MDOT ships as the complete microphone boom arm, TwinPlex dual-diaphragm capsule, and 1.6 mm Plex cable — the same construction used in new TH53 units. The cable measures 66 inches (1.67 m) and carries nano-coating for moisture and sweat resistance, critical for extended-wear performance in stage and broadcast environments. This Shure TH53 replacement boom arm restores the full TwinPlex element performance of the parent headset: 20 Hz–20 kHz frequency response, 142 dB SPL max, and 69.5 dB SNR. At just 12 g, the assembly preserves the near-weightless comfort that makes the TH53 suitable for all-day wear by presenters, actors, and broadcast talent. The boom snaps into the existing TH53 headset frame (RPM53T-HF) and is field-switchable between left and right positioning without tools.
Key Features
- Microdot Connector — Standard Microdot termination supports a wide range of professional wireless bodypack systems via readily available adapters, including compatibility with Sony Hirose 4-pin bodypacks using a DPA DAD6008 adapter.
- TwinPlex Dual-Diaphragm Capsule — OEM capsule identical to new TH53 production, delivering flat omnidirectional response across 20 Hz–20 kHz with robust low-frequency performance.
- 1.6 mm Plex Cable — Ultra-thin, high-durability cable with redundant grounding and nano-coating for sweat and moisture resistance; tested to exceed standard cable lifespans in demanding stage use.
- Tan Finish — Matches the TH53 tan headset frame for a discreet, low-visibility appearance against lighter skin tones in theater and broadcast applications.
- 66-Inch Cable Length — Provides adequate routing length from boom tip to bodypack transmitter without modification or extension.
- 12 g Lightweight Assembly — Boom arm plus cable weighs just 12.0 g (0.42 oz.), maintaining the TH53's class-leading comfort for extended wear.
- Tool-Free Field Replacement — Snaps directly into the TH53 headset frame; left/right boom positioning is switchable after installation per TH53 user guide procedure.
Typical Applications
- House of worship — replacement parts for wireless headset systems used in sermon and musical performance reinforcement
- Broadcast studio — maintenance of talent headset microphones for on-camera presenters and radio hosts
