When switched into Bridged-Mono mode, the amplifier in use shall deliver a range from 800 to 3800 watts RMS into 8 ohms. All amplifiers shall have the ability for input attenuation, channel mute, channel polarity, input level, output voltage, output current, clipping, temperature, and power on/off be controlled or monitored through the standard, built-in Ethernet port using Proteane Software™. The amplifiers shall have the capability to replace the input module with either a 32 bit/96kHz, Proteane DSP module featuring both analog and digital (AES3) inputs, two additional processed output channels and extensive digital signal processing or the PNE-C2 CobraNet module. Dimensions of the amplifiers shall be 19”W x 3.5”H x 15.5”D, with a weight range of 22 to 24 pounds. The amplifiers shall utilize a state-of-the-art, efficient, two-stage high speed switched mode power supply. Cooling shall be accomplished by the use of a temperature sensitive variable speed fan with front to back airflow. The amplifier shall have a selectable input gain of 26dB, 32dB or 1.4V. Frequency response shall be 20 Hz - 20 kHz, +/- 0.15 dB. Hum and noise shall range from >98dB to 112dB below full output (20Hz to 20KHz A-weighted) and SMPTE intermodulation distortion shall be <.01% (8 ohm load, 10dB below rated power). Total Harmonic Distortion (20Hz - 20KHz at 8 ohms) shall be <.01% (8 ohm load, 10dB below rated power, 20Hz-10 kHz). Each amplifier channel shall be supplied with a calibrated stepped input attenuator located on the front panel with the capability of the attenuators to be disabled. Each pair of inputs shall have a selectable, bypassable high pass filter of 12dB/octave at 30Hz and 50Hz, a switch to select stereo or mono mode and a switch to select dual or bridge mode. There shall be an input ground switch located on the rear panel to select chassis or floating ground operation and a selectable clip limiter with off, slow, and fast settings. The inputs shall be active balanced design, with an impedance of 20K ohm with a maximum input level of +21dBu. Input connections shall be XLR-1/4” Neutrik combo connectors and 6-pin Euroblock. XLR male connectors shall be provided for looping to additional amplifiers. Output connectors shall be locking Neutrik Speakon. Models 800 and 1200 shall have a 4 position screw terminal strip with safety cover as an additional output. The amplifiers shall have front panel indicators for power, standby, protect, bridged mono, parallel mono, and data communications. Each channel shall have signal indicators for clip, -6 dB, -12 dB, -18 dB levels, temp, output current. The amplifier shall have built in protection for inrush current, temperature, output DC, SOA of power transistors, output over- current and mains power. The amplifiers shall be capable of operation by means of its own built-in power supply connected to 110 - 125VAC, 220 - 250VAC, 50/60Hz. The amplifier shall be ...
