The GRQ3121 from Sabine combines eight audio products into a single affordable, all-digital package with an easy-to-use hands-on interface. Virtually all installation or live audio issues can be dealt with, without running out of DSP power.
All processors can be run concurrently. Control of the thirty-one band graphic EQ can be handled both from the front panel as well as by remote computer control. Additional EQ is available via software control and the twelve filters can be configured as either parametric filters or fixed/auto feedback control filters.
A digital limiter provides speaker protection and a digital compressor, with full function control, delivers audio program processing. A 1 x 2 crossover set-up features multiple filter profiles while a digital delay can be set up to time aligns speakers.
Included GRQ2 Remote Control Software provides instant access to all front panel controls and to an additional layer of functions. The engineer can view and edit frequency response curves, view edits before executing them and take advantage of unlimited GRQ2 file storage.
