Ashly GQX-1502 Technical Notes & Specifications

GQX-1502 Graphic Equalizer
ARCHITECTS SPECIFICATIONS
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 cen-
tered, and shall have a maximum in/out level of +22dBu.
Frequency response shall be ±.25dB 20Hz to20kHz. Hum
and noise shall be at least -95dBu and SMPTE inter-
modulation 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 connections. 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 charac-
teristics 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-adjust-
able 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 -infinity to +6dB, 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 100-240VAC, 50-
60Hz, 24W. The unit shall be an Ashly Audio GQX-1502.
