The GRQ3121S from Sabine combines eight audio products into a single affordable, all-digital package. The unit is identical in function to the GRQ3121 except for the lack of front panel control. Virtually all installation or live audio issues that require system security can be dealt with, without running out of DSP power.
All processors can be run concurrently. Control of the thirty-one band graphic EQ are handled by remote computer control, either in real time or as a permanent set-up. 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.
The GRQ2 Remote Control Software provides instant access to what would be 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.
