Wireless freedom. Seamless function.


Digital Wireless Systems

How can you get more fans on their feet? Add more freedom to your performance— without pushing a single button. Ideal for small and medium stages, GLX-D® Digital Wireless is the easy way to go wireless with less worry.

How It Works

Going wireless gives you more freedom on stage. And GLX-D gives you more freedom from interference. In using the globally license-free 2.4Ghz band, the system maintains clear channels through automated management of available frequencies. From the first note to the last.

Why it's better

Hear the clear

With a 20 Hz–20 kHz response and a 120 dB dynamic range, your digital sound can go big while your performance goes free.

Rock on and on

One lithium ion battery allows up to 16 hours of continuous use right out of the box, and everything you need is included.

Solid signal

LINKFREQ Automatic Frequency Management continuously scans for open frequencies and seamlessly switches before dropouts can stall the show.
