Powerflex-4400 Four Chanel Amplifier
The power amplifier shall be a multichannel unit consisting of 
four independent channels. Each amplifier shall be able to deliver 
275 watts into 8 ohms, or 400 watts into 4 ohms. In addition, 
bridged pairs shall be able to output 800 watts each into 8 ohms.
The amplifier shall have a gain of 30.1dB and an input sensitivity 
of 1.25 Volts RMS for full rated output. Frequency response shall 
be 20Hz to 20kHz +/- 0.5dB at 8 ohms. The unit shall be stable 
into any load, including pure capacitors and inductors. Hum and 
noise shall be at least 100dB below full output (A-weighted) and 
SMPTE intermodulation distortion shall be less than 0.2%. Total 
Harmonic Distortion (20Hz - 20KHz at 8 ohms) shall be less than 
0.2%.
 
Each amplifier channel shall be supplied with an input attenuator 
located on the rear panel input module. Each pair of inputs shall 
have a bypassable high pass filter of 12dB/octave at 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 input module to select chassis or floating ground operation.
The inputs shall be active balanced design, with an impedance of 
10K ohm accessible  with combination XLR - 1/4” jacks and euro-
block connectors. The outputs shall be terminated with a 5-way 
binding post connector.
Individual channel indicators for protect, thermal overload, clip 
and signal present shall be LEDs located on the front panel. 
Cooling shall be supplied by a temperature sensitive three-speed 
fan drawing air from the front of the unit and exiting through the 
rear.
The unit shall be capable of operation by means of its own built-
in power supply connected to 110 - 125V AC, 220 - 250V AC, 50/
60Hz. Dimensions of the unit shall be 19”L  X 5.25”H X 16.5”D. 
The chassis shall be constructed from steel with an aluminum 
face panel and weigh 45lbs. 
The unit shall be the Powerflex 4400 manufactured by Ashly
