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.

Our widely-popular Protea™ ne24.24M Matrix Processor will more than satisfy your requirements for any zoned system.

When your install requires input/output matrixing with signal processing it doesn’t get much easier than programming your channels using Protea™ ne Software on your PC. The ne24.24M uses modular expansion cards to provide up to 24-channels of audio matrixing and processing. The base unit offers a 4-input/4-output configuration. Each input and output expansion card has an individual DSP processor allowing you to expand the total input or output 4 channels of DSP processing at a time. These cards are easily installed in the field without the need to reprogram the device.

Matrixing allows you to route any input to any output and control individual levels once they have been assigned. Fixed path architecture and extensive processing power per channel will reduce the amount of time it takes to set up your system.

An optional GPO Logic Card allows the ne24.24M to trigger projection screens, curtains or lights. The logic card is installed in place of a 4-input or 4-output card and occupies one of the four expansion slots.
