ne4800mc

Connecting and controlling an audio processor for networked systems is simplified with our ne Digital Signal Processors. Complimentary to our amplifiers, our processors offer easy setup and control using standard 10/100 Ethernet protocol and Protea ne Software. No special outboard control units are needed.

Standard units are analog line input/output format of ne4400 (4x4), ne4800 (4x8), and ne8800 (8x8, shown above) with four option bays supporting network audio, AES3, and mic input options. The DSP signal processing library is extensive and utilizes multiple SHARC 32-Bit processors with sample rates of either 48kHz or 96kHz.

Processing blocks include either a 4x4, 4x8 or 8x8matrix mixer, a full array of graphic, parametric and all pass equalization, crossover filters including 8th-order Butterworth, Bessel, Linkwitz-Riley and notched Linkwitz-Riley. The Protea Software Suite also includes an extremely advanced automatic feedback suppressor, FIR filter capability, gain sharing automatic microphone mixing, ambient noise sensing and level adjustment, autolevelers, compressors, matrix duckers, limiters, frequency-keyed noise gates, signal delay up to 1,365ms on every channel and your choice of sinewave, pink or white noise generators.

All programming is accomplished using standard10/100 Ethernet or RS-232 protocol and Protea neSoftware on a PC platform. Hot-plug software control allows you to plug any function into any channel block even when running live audio with no recompiling necessary. Automatic DHCP network IP configuration reduces network set up time. Multi-level software security with password access assures you a tamper-proof audio system

ne4800: Architect & Engineering Specs
The digital signal processor unit shall be analog line input / output with four option bays for supporting Cobranet or Dante network audio, AES/EBU, and mic input options. The processor shall consist of four inputs and eight outputs. The processor shall use fixed-path architecture with hot-plugable audio functions anywhere in the signal path to reduce set-up time. All control and monitoring programming shall be accomplished using a PC platform and standard Ethernet network connection or RS-232 protocol. Multi-level security with password access and no front panel controls shall insure tamper-resistant operation. Input / output channel processing blocks shall include a full array of variable-Q graphic and parametric equalization.

The processor shall have crossover filters to 8th order Butterworth, Bessel, Linkwitz, and Notched-Linkwitz. The processor shall have an advanced automatic feedback suppressor, FIR filter capability, autolevelers, compressors, matrix duckers, limiters, frequency-keyed gates and time delay to 1365ms. Sinewave, pink noise, and white noise generators shall be included in the processor. A matrix mixer shall allow any input to be routed to any output at any level. A gain-sharing automixer may also be enabled on any input signal of any output mixer. Rear panel Euroblock connectors shall include eight logic input or output connections, plus eight remote potentiometer level controls. Word clock input and output BNC connections shall be provided for digital audio frame locking to a house sync. The DSP processor shall mount in a standard 19" rack using 2 spaces (3.5" high).
