Shure QLXD1-H51 Bodypack Transmitter

Shure QLXD1-H51 Digital Wireless Bodypack Transmitter

The Shure QLXD1-H51 is a professional, metal-bodied digital wireless transmitter designed for use with QLX-D series receivers in the H51 frequency band (534–598 MHz). This compact device provides completely transparent 24-bit digital audio transmission and boasts a wide dynamic range of over 120 dB. This feature eliminates the need for input gain adjustment on the transmitter – it automatically adapts to various sound source levels, from a quiet whisper to a loud guitar.

The QLXD1 is an ideal choice for vocals and instruments in presentations, musical events, or church settings. Advanced AES-256 encryption is used to ensure secure data transmission, making the system suitable for confidential business meetings or government institutions. The transmitter features a standard TQG (TA4M) connector, compatible with Shure lavalier, headset microphones, and instrument cables. The device is powered by two AA batteries or a Shure SB900B lithium-ion rechargeable battery, which can be charged using external charging contacts (with an additional charging station).
