    NE4250.70 - Overview

    Connecting and controlling an amplifier for networked systems has now been simplified with Ashly's NE Series amplifiers. Network Enabled (NE) amplifiers offer ease of use, setup and control using standard 10/100 Ethernet protocol and Protea NE Software. No special outboard control units are needed.

    Four-channel models with output power at 250W are available to fill a wide variety of low impedance, 25V, 70V and 100V performance installation or constant voltage applications. 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 signal processing 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.
