1U Chassis
Fixed Architecture DSP
SR-LMS Series
32-bit SHARC loudspeaker management — 2, 3 or 4 inputs with full matrix assignment.
A digital matrix processor built on a 32-bit SHARC engine with 96 kHz sampling and 24-bit conversion. Input processing covers high-cut and low-cut filters, eight bands of PEQ, noise gate, gain, mute, phase, delay and linking; outputs add crossover, nine PEQ bands and compressor/limiter. Every input and output can be freely matrix-assigned and renamed.
