Ashly H35P12100 User Manual

GQX-1502

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 45mm travel, metal actuator shafts and a tactile center
detent. The range of equalization per band shall be ±15dB. The
equalizer shall have a gain of unity with all sliders centered, and
shall have a maximum in/out level of +22dBu. Frequency response
shall be ±.25dB 10Hz to20kHz. Hum and noise shall be at least ­96dBu 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. Inputs and outputs shall be active (transformerless) balanced
type on XLR ,1/4" phone jacks and barrier strip terminals.
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 a 12dB per octave high pass filter at
40Hz, equipped with a bypass switch. An LED indicator shall
show overload conditions. Input gain shall be adjustable over a
range of ±15dB, and an overall EQ bypass switch shall be includ­ed. The equalizer shall weigh 9.5 lbs net and mount in a standard
19" rack using 2 spaces (3.5" high). The power requirement shall be
110-115VAC, 50-60Hz, 12W. The unit shall be an Ashly Audio
GQX-1502.
