Ashly NE425070PE Details

The Ashly NE-4250.70pe is a 4 Channel 70V Amp + DSP.

Ashly launches the new NE-Series (NE = Network Enabled) with sixteen multi-channel amplifiers. Targeted for the performance installation and constant voltage markets, these amplifiers add a new level of power and control from the simplest to most advanced audio system applications. The models include both four and eight channel low impedance, 25V, 70V and 100V amplifiers and provide 250W of power per channel. Network Enabled (NE) amplifiers offer ease of use, full setup, control and monitoring using standard 10/100 Ethernet protocol and Protea NE Software. No special outboard control units are needed. NE Series amplifiers are offered two ways; standard input with euroblock connectors and "pe" (Protea Enabled) with euroblock input connectors and world renowned Protea DSP signal processing.

The DSP library is extensive and utilizes two SHARC 32-bit/96kHz processors. Processing blocks include Graphic, Parametric, Notch and Shelving Equalization, High-, Low- and All-Pass Filters (HPF/LPF/APF) with up to 48dB/Octave slopes, Delay, Compressor/Limiter, Gate, Ducking, Auto-leveler, Gain and Signal Generators (sinewave, white and pink noise).

A full Matrix Mixer with assignable routing allows any input to drive any or all amplifier outputs. Presets can be used to store and retrieve global parameters of an entire amplifier's control surface and DSP section.

Additionally, each amplifier also provides DC voltage control of the attenuators which makes it a snap to control volume from remote locations, preset recall, Remote Power Standby and data in and out ports for connecting accessories like the WR-5 to control user selected parameters. There are LED indicators for power, standby, protect, network communications and each channel has a four-step signal meter, bridge mono, temperature and current indicators. Four-channel Mic-pre, AES/EBU, and Cobranet input modules will be available as options.
