NE Series specifications

Connecting and controlling an audio processor for networked systems has

now been simplified with Ashly’s NE-Series ne4400, ne4800 and ne8800 digital

signal processors. These Network Enabled (NE) processors offers ease of use,

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 4x4 (4400), 4x8 (4800),

and 8x8 (8800) with four option bays supporting network audio, AES/EBU, and

mic input options. The DSP signal processing library is extensive and utilizes

multiple SHARC 32-bit/96kHz processors with sample rates of either 48 KHz

or 96 KHz. Processing blocks include an 8x8 matrix mixer, a full array of vari-

able Q graphic and parametric equalization, crossover filters to 8th-order

Butterworth, Bessel, Linkwitz, and Notched-Linkwitz, an extremely advanced

automatic feedback suppressor, autolevelers, compressors, matrix duckers,

limiters, frequency-keyed noise gates, time delay up to 1365 ms on every

channel, sinewave, pink noise, and white noise generators.

All programming is accomplished using standard 10/100 Ethernet or RS-232

protocol and Ashly’s Protea NE Software 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 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 you a

tamperproof audio system.

Additional features include: network audio routing at matrix mixer to inputs

from outputs, or in/out of matrix mixer, 8 link groups on most functions, auto-

matic master clock switchover between network, word clock, AES/EBU, and

internal clock, a high-performance analog audio path – dynamic range

exceeding 114 dB, support of Ashly digital remote controls, programmable 8

channel 5V logic input or output control, 8 channels of 0 to 5V analog level

control, word clock input and output and a front panel full meter bridge with

mute keys.

Available hardware options are: 4-channel mic/line input option with soft-

ware controllable gain and phantom power, CobraNet network audio input

and output, EtherSound network audio input and output, AES/EBU digital

audio input and AES/EBU digital audio output.
