XR Series
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.
With wear-free digital potentiometers, sequential remote power on, alive contacts for easy supervision, computer controlled monitoring.
