The ne4400d from Ashly is a 4 input, 4 output network enabled digital signal processor that offers ease of use, setup and control using standard 10/100 Ethernet protocol and Protea NE software. No special outboard control units are needed. The DSP signal processing library is extensive and utilizes multiple SHARC processors.
Processing blocks include an 8 x 8 matrix mixer, a full complement of variable Q graphic and parametric EQ, up to 8th-order Butterworth, Bessel, Linkwitz,and Notched-Linkwitz crossover filters, and an advanced automatic feedback suppressor. Also included are autolevelers, compressors, matrix duckers, limiters, frequency-keyed noise gates, time delay up to 1365ms on every channel, sinewave, pink noise and white noise generators.
All programming is accomplished using Ethernet or RS-232 protocol and the Protea NE software running under Windows. Hot-plug software control allows for plugging any function into any channel block even when running live audio with no latency or recompiling necessary. Automatic DHCP network IP configuration reduces network set up time. No front panel controls and multi-level software security with password access assures a tamper-proof audio system.
The ne4400d includes 4-channel AES/EBU digital input and output. The digital output mirrors the analog output, while the input can be switched to digital plus analog, or digital only.
