Product Details

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.
