Protēa™ ne series dsp matrix processors
Standard ne DSP units are analog line input/output format of ne4400 (4×4), ne4800 (4×8), and ne8800 (8×8) with four option bays supporting network audio, AES3, and mic input options. Processing blocks include either a 4×4, 4×8 or 8×8 matrix mixer, a full array of graphic, parametric and all pass equalization, crossover filters including 8th-order Butterworth, Bessel, Linkwitz-Riley and notched Linkwitz-Riley.
No special outboard control units are needed. Connecting and controlling an ne audio processor for networked systems is simplified and call-back free.
