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

Four, 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 process- ing.

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 out- puts. 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 attenu- ators 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 modules will be available as options. Eight-channel NE series amplifiers are also available
