Ashly GQX-3102 Quick start guide

GQX-3102
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 cen-
tered, and shall have a maximum in/out level of +23dBu.
Frequency response shall be ±.25dB 20Hz to20kHz.
Hum and noise shall be at least -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 both XLR,
1/4" phone jacks and euroblock connectors. Individual
filters shall be Wein-bridge type and connected in a sum-
ming 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 equal-
izer 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 over -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. The unit shall be an Ashly
Audio GQX-3102.
