The four-channel power amplifier shall deliver a minimum power of 150 Watts RMS per channel into 8 Ohm loads and 250 Watts RMS per channel into 4 Ohm loads with all channels operating. When switched into the bridged-mono mode, channels 1+2 or 3+4 of the amplifier shall deliver at least 500 Watts RMS into an 8 Ohm load. The power amplifier shall include Euroblock input connectors and Euroblock output connectors. It shall have balanced analog inputs. The power amplifier shall have remote standby for power up, DC remote level control and contact closure preset recall. It shall have Ethernet control and monitoring of power functions, level, mute, polarity, temperature, current, and amplifier fault conditions. The frequency response shall be 20Hz to 20kHz ±1.0dB. Signal-to-Noise shall be greater than 105dB unweighted and SMPTE intermodulation distortion shall be less than 0.5% into an 8 Ohm load, 10dB below rated output. The front panel shall provide the status of power, standby, protect, power switch disable, signal level, bridge, over-temperature, over-current, and Ethernet communication. The power amplifier shall have an internal factory-installed digital signal processing (DSP) option controlled using Protea (network-enabled) software. Each amplifier input channel shall 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 shall allow any input to drive any or all amplifier outputs. Outputs shall have the same DSP functions as inputs, with the addition of FIR filters, and a fast, automated crossover setup. Both inputs and outputs shall copy/paste their settings to other channels, or link with one or more other channels to track their settings. Presets shall be used to store and retrieve global parameters of an amplifier's control surface and DSP section from a file. Sub-Presets shall allow 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 shall be stored within the amplifier, and shall be recalled in real-time via Ethernet from a computer using Protea software. The power amplifier will be capable of having factory-installed AES3, CobraNet®, or Dante® interface options.
