Shure RPM53T/O-MTQG – Replacement Boom Arm for TH53, Tan, MTQG

Product Overview

The Shure RPM53T/O-MTQG is the OEM replacement boom arm and cable assembly for the TH53 TwinPlex omnidirectional headset in tan, terminated with an MTQG (TA4F-compatible) connector. This Shure TH53 replacement boom arm is the direct-connect solution for integrators deploying Shure wireless bodypacks — including ULXD1, QLXD1, AD1, ADX1, and SLX1 transmitters — in theater, house of worship, broadcast studio, and corporate live event environments. The MTQG connector is the most widely used Shure bodypack termination, making this the preferred replacement for most commercial AV deployments.

Product Description

The RPM53T/O-MTQG ships as a complete assembly: the TwinPlex dual-diaphragm boom capsule and 1.6 mm Plex cable pre-terminated with an MTQG connector, ready for direct connection to all Shure TA4F bodypacks. The 3-wire source-follower wiring design provides positive polarity with respect to ground (pin 3 audio, pin 2 bias, pin 1/shell ground), eliminating the need for adapters or rewiring in standard Shure wireless systems. Cable length is 66 inches (1.67 m) with nano-coating for moisture resistance. This assembly restores the full TH53 element specifications: 20 Hz–20 kHz frequency response, 142 dB SPL maximum, and 69.5 dB SNR. At 12 g, it maintains the TH53's near-weightless comfort profile for extended-wear commercial applications.

Key Features

• MTQG (TA4F-Compatible) Connector — Direct-connect termination for all Shure TA4F wireless bodypack transmitters; no adapter required for the majority of Shure wireless systems in commercial AV deployments.
• 3-Wire Source-Follower Wiring — Standard Shure wiring scheme (pin 2 bias, pin 3 audio, pin 1 ground) for correct polarity and optimal performance with Shure bodypacks.
• TwinPlex Dual-Diaphragm Capsule — OEM omnidirectional element identical to new TH53 production, with flat response from 20 Hz–20 kHz and robust low-frequency extension.
• 1.6 mm Plex Cable — Nano-coated, sweat-resistant cable with redundant grounding and no memory effect; engineered for longevity in high-use stage and broadcast environments.
• Tan Finish — Matches the TH53 tan headset frame (RPM53T-HF) for low-visibility placement against lighter skin tones in theater and live broadcast.
• 12 g Lightweight — Ultra-light assembly preserves the TH53's extended-wear comfort for talent in long-duration performances and events.
• Field-Replaceable — Snaps into the TH53 headset frame without tools; left/right boom positioning is switchable after installation.

Typical Applications

• House of worship — headset microphone maintenance for wireless sermon and performance reinforcement using Shure bodypack systems
• Theater — replacement boom arms for theatrical productions requiring discreet, low-visibility wireless headset microphones
• Broadcast studio — talent headset upkeep for on-camera presenters and radio hosts on Shure wireless systems
• Corporate meeting space — headset lifecycle management for all-hands and large-format presentation environments

Frequently Asked Questions

Which Shure bodypacks are compatible with the MTQG connector?
The MTQG connector works directly with all Shure TA4F-style bodypacks, including the ULXD1, QLXD1, SLXD1, AD1, ADX1, and SLX1 transmitters. It is the standard Shure bodypack termination for most commercial wireless systems.

Is this compatible with Lectrosonics bodypacks?
With the appropriate TA5F adapter and Servo Biased wiring (WA435), the MTQG version can be used with Lectrosonics TA5F bodypacks. Refer to the TH53 wiring guide for specific pin configurations.

Is the headset frame included?
No. This SKU is the boom arm and cable assembly only. The tan headset frame is sold separately as RPM53T-HF.

Does this restore full TH53 audio performance?
Yes. This is the OEM replacement assembly with the same TwinPlex dual-diaphragm capsule used in new TH53 production, restoring the full 20 Hz–20 kHz response and 142 dB SPL handling of the headset.
