Ashly NE4250.70PEAC Overview

The 4-Channel 1000W Network-Enabled Power Amplifier from Ashly delivers a minimum power of 250W RMS power per channel into 70V loads with all channels operating. The amplifier features pre-installed AES3 input card with pass-thru, CobraNet, and the Protea DSP Software Suite; and is designed around an energy efficient Class-D platform with a switching power supply. When switched into bridged-mono mode, channels 1+2 or 3+4 of the amplifier delivers over 500W RMS into an 140V load.

The power amplifier includes Euroblock input connectors, Euroblock output connectors, and balanced analog inputs. Besides remote standby for power up, DC remote level control, and contact closure preset recall, the amplifier also features Ethernet control & monitoring of power functions, level, mute, polarity, temperature, current, and amplifier fault conditions. The front panel indicates power status, standby, protect, power switch On/Off, signal level, bridge, temperature & current levels, and Ethernet communication. The amplifier mounts in a standard 19” rack using two spaces (3.5” high).

The power amplifier has an internal factory-installed Digital Signal Processing (DSP) controlled using the Protea Software Suite (network-enabled). Each amplifier input channel can be configured with pluggable DSP blocks to have its own dynamics control, gain functions, graphic and/or parametric EQ, Hi-pass/Lo-pass filters, time delay, metering, and test signal generator. A mixer section with assignable routing allows any input to drive any or all amplifier outputs.

Outputs have the same DSP functions as inputs, with the addition of a quick and automated crossover setup. Both inputs and outputs duplicate their settings to other channels, or link with one or more other channels to track their settings. Presets can be used to store and retrieve global parameters of an amplifier’s control surface and DSP section from a file. Sub-presets allows for a collection of individual DSP function parameters within and across both channels of an amplifier to be stored and recalled as a set, affecting only those parameters which have been tagged. Up to 35 presets/sub-presets can be stored within the amplifier and recalled in real time via Ethernet from a computer using the Protea Software Suite.
