XR Series - Intelligent Power
New Horizons.

A lightweight with enormous power output. Combined with digital signal processing.
That's what we call flexibility! Locally controlled or completely networked.
No matter what the requirements are.
The integrated powerful digital signal processor (DSP) and controller allows
for a troublefree and easy adjustment to any acoustical environment.
Wear-free digital potentiometers, sequential remote power on,
alive contacts for easy supervision, computer controlled monitoring -
 its enless list of useful feature make it the right choice for any installation.
