Overview

The Shure RPM400TQG is a wired preamplifier adapter that converts the TQG connector found on Shure's TwinPlex lavalier microphones — including the TH53, TL45, TL46, TL47, and TL48 — to a standard XLR output. This allows users to plug these miniature microphones directly into mixers, audio interfaces, recorders, or any other equipment with XLR inputs, without needing a wireless bodypack transmitter in the signal chain. The internal preamp circuit is optimized for low-noise operation, ensuring that the signal reaching your recording or mixing gear retains the full clarity and detail of the TwinPlex capsule.

Practicality is well considered in the design. A built-in belt clip lets talent or operators wear the unit comfortably during stage performances, broadcast segments, or location recordings where cable runs need to stay tidy. The housing is compact at 4.7 x 3.4 x 2.4 inches, and while its 11.2-ounce weight is noticeable, the trade-off is a solidly built enclosure that can handle the rigors of professional audio work day after day.
