Digital wireless system combines robust wireless performance with easy set-up and digital audio quality. Features include IR sync between transmitters and receivers, AES 256 encryption for security, and operation of up to 22 transmitters per 8MHz.

How it works

What’s the secret to giving you more wireless with less worry? Control. QLX-D lets you streamline setup across multiple receivers, and Wireless Workbench® software gives you real-time access, monitoring and control throughout the performance. You can even manage the system from your iOS device for maximum convenience.

Why it's better

True to the source

The 24-bit digital audio and the wide frequency response capture the sound as clearly and accurately as it was produced.


Persistent power
The rechargeable lithium-ion battery option extends performance on stage, simplifies workflow and saves money versus replaceable alkaline batteries.


Secure sound
Confidentiality is ensured via AES-256 advanced encryption that generates a randomized key for each use.
