Our graphic EQs utilize Wein-Bridge filters using precision components and our specially designed summing amplifiers provide extremely accurate response, low noise, negligible distortion, and excellent immunity to magnetic fields. All filters exhibit true constant"Q" response, with absolute minimum ripple.

Ashly EQs are well known as the go-to brand for analog processors for any concert application or commercial pro install. The GQX-3102 features 2-channels of 31-band 1/3-octave EQ, tunable hi-pass filter circuit, switch-select-able cut or boost of either 6dB or 15dB and 10-segment, 2-color LED meter displays, and clip LEDs. The full-throw 45mm faders have a metal-shaft with the center detented position utilized as an "on/off" switch for that filter to minimize noise levels when the filter is not in use.

The graphic equalizer shall be stereo (2 channels). Each channel shall consist of 31 bands centered on standard ISO frequencies at intervals of 1/3 octave and covering a frequency range of 20Hz to 20kHz. Individual bands shall be activated by linear slide faders with a 45mm travel, metal actuator shafts and a tactile center detent. The range of equalization per band shall be either ±6dB or ±15dB selected via a 2-position switch. 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 to20kHz. Hum and noise shall be less than -95dBu and SMPTE intermodulation distortion or THD shall be less than .01% at full output. Input impedance shall be 20k ohm balanced, 10k ohm unbalanced.

Output impedance shall be 200 ohm servo-balanced. Inputs and outputs shall be active (transformerless) balanced type on XLR, 1/4" phone jacks, and Euroblock connectors. 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 tunable from 14Hz to
280Hz, equipped with a bypass switch. A 10-position, 2-color LED level meter shall be employed to show overall output level and LED indicators shall show overload conditions.

Input gain shall be adjustable from -infinity to +6dB, and an overall EQ bypass switch shall be included. The equalizer shall weigh 13lbs net and mount in a standard 19" rack using 3 spaces (5.25" high). The power requirement shall be 100-240VAC, 50-60Hz, 24W.
