MQX-2310 Architect & Engineering Specs 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 25mm travel, 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 to 20kHz. Hum and noise shall be at least -94dBu, and SMPTE intermodulation distortion or THD shall be less than .01% at +20dBu. Input impedance shall be 20k ohm balanced, 10k ohm unbalanced. Output impedance shall be 200 ohm servo-balanced, 100 ohm unbalanced. Inputs shall be active (tranformerless) balanced type on XLR, 1/4”, 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 at 40Hz equipped with a bypass switch. Green signal presence and red clip indicators shall show critical operating levels. Input gain shall be adjustable from -infinity to +6dB, and an overall EQ bypass switch shall be included. The equalizer shall weigh 8.5 lbs net and mount in a standard 19” rack using 2 spaces (3.5” high). The power requirement shall be 100-240VAC, 50-60Hz, 24W. The unit shall be an Ashly Audio MQX-2310.
