The graphic equalizer shall be stereo (2 channels). Each channel shall consist of 15 bands centered on standard ISO frequencies at intervals of 2/3 octave and covering a frequency range of 25Hz to 16kHz. Individual bands shall be activated by linear slide faders with a 25mm travel, and a tactile center detent. The range of equalization per band shall be switchable between ±15dB or ±6dB.

The equalizer shall have a gain of unity with all sliders centered, and shall have a maximum in/out level of +23dBu. Frequency response shall be ±.25dB 20Hz to
20kHz. Hum and noise shall be at least -96dBu and SMPTE intermodulation distortion or THD shall be less than 0.01% at +20dBu. Input impedance shall be
20k ohm balanced, 10k ohm unbalanced. Output impedance shall be 200 ohm balanced, 100 ohm unbalanced. Inputs and outputs shall be active tranformerless) balanced type on both XLR and 1/4inch phone jacks.

Individual filters shall be Wein-bridge type and connected in a summing circuit optimized for minimum filter interaction and constant bandwidth at any slider
setting. Boost and cut characteristics shall be fully symmetrical, with the filter being electrically removed from the circuit in the center (flat) position. Individual filters shall be accurate to within 3% of indicated center frequency and shall be non-adjustable to insure long term accuracy. The equalizer shall also include an 18dB per octave high pass filter at 20Hz, internally selectable. A green
signal presence and red clip indicators shall show critical operating levels. Input gain shall be adjustable over minus infinity to +6dB, and an overall EQ bypass
switch shall be included. The equalizer shall weigh 6.5 lbs net and mount in a standard 19” rack using 1 space (1.75inch high). The power requirement shall be 90- 125VAC, 50-60Hz, 10W. The unit shall be an Ashly Audio MQX-2150.
