Frequency bands shall be activated by individual upand down tactile switches. The range of equalization per band shall be ±15dB in0.5dB increments. The equalizer shall have a gain of unity with all bands set at zero,and shall have a maximum in/out level of +20dBu. Frequency response shall be±.25dB 20Hz to20kHz. Dynamic Range shall be greater than 110dB (20-20KHz,unweighted) and SMPTE intermodulation distortion or THD shall be less than0.01% at 1KHz, +20dBu. Input impedance shall be 18K ohms balanced. Outputimpedance shall be 200 ohms. Inputs and outputs shall be balanced type on XLRand 1/4" phone jacks. Individual filters shall be of a constant Q reciprocal filterdesign. Boost and cut characteristics shall be fully symmetrical. The equalizer shallalso include on each channel a 24dB per octave high pass filter adjustable from20Hz to 10.6KHz, a 24dB per octave low pass filter adjustable from 33Hz to20KHz, a full function, pre/post switchable compressor/limiter with adjustablethreshold, ratio, attack and release controls, and a time delay capable of a maxi-mum of 1.364 seconds adjustable in 20us increments. A 240 X 64 fluorescent back- lit LCD display will show all parameter, function and utility information. LEDindicators shall show signal present and mute conditions. Channel gain shall beadjustable over a range of +6dB to - infinity in 0.5db increments. Control of theunit shall be from the front panel, via the optional 4.24RD remote control, via RS-232 serial port using Ashly Protea System Software, or via MIDI. The equalizer shallweigh 14 lbs net and mount in a standard 19" rack using 2 spaces (3.5" high). Thepower requirement shall be 90-125VAC (180-250VAC, switchable), 50-60Hz, 30W.The unit shall be an Ashly Audio Protea System II 4.24G.The optional remote controller shall operate all functions of the Protea unitusing push-buttons and shall be phantom powered from the Protea unit so that nobatteries or AC line cords are needed while controlling the Protea unit.Connections between the controller and Protea unit shall be accomplished usingstandard XLR mic cables. A 240 X 64 fluorescent backlit LCD display shall show allparameter, function and utility information. LEDindicators shall show channeland mute conditions. The remote controller shall have a low profile for desk-topoperation. The remote controller shall be the model Protea System II 4.24RD.
