Shure QLXD2/KSM9 Digital Handheld Wireless Microphone Transmitter

The Shure QLXD2/KSM9=-J50A is a digital handheld wireless microphone transmitter that pairs the proven QLX-D platform with the respected KSM9 condenser capsule. It gives vocalists, presenters, and worship leaders a way to move freely while keeping studio-level clarity in front of any audience.

The KSM9 capsule lets you switch between cardioid and supercardioid pickup patterns, making it easy to adapt to crowded stages, reflective rooms, or tightly packed worship spaces. Because the signal travels as 24-bit digital audio, every nuance reaches the mixer with very low latency and without the hiss or companding artifacts common to analog systems.

Engineers who need dependable coverage will appreciate the operating range of up to 330 feet. Security-conscious users can enable AES-256 encryption so corporate meetings or government events stay private. Infrared sync locks the transmitter to a QLX-D receiver in seconds, and the selectable 1 mW or 10 mW RF output helps tame challenging radio-frequency environments.

The aluminum body stands up to touring life yet feels light in the hand, and the clear OLED screen keeps vital information visible on dark stages. Two AA batteries power the transmitter for as long as nine hours; add the optional Shure rechargeable pack when longer shows or back-to-back services require even more uptime.

Whether you manage a busy rental inventory, mix front of house for a touring act, or lead a production team in a modern church, the QLXD2/KSM9=-J50A delivers the sound, reliability, and simple workflow that let you focus on the performance instead of the gear.
