The GQX-Series is available in three different configurations: the GQX-1502 features two channels of fifteen-band 2/3 octave equalization and a switchable high-pass filter. The GQX-3101 is a single-channel thirty-one band model, while the GQX-3102 features two channels of 1/3 octave EQ.

Both the third-octave models offer tunable high-pass filter circuits from 8Hz to 200Hz and 10-segment, two color LED meter displays, referencing 0 VU to +4dBu. Each model in the GQX-Series features switch-selectable cut or boost of either 6dB or 15dB, and carry the same Five Year Worry-Free Warranty offered on all commercial sound products from Ashly.

The GQX models are designed to be significantly quiet without the need for noise reduction to be built into the equalizer circuit. Double-sided circuit boards with ground plane design are used in the filter sections for improved RFI and electrostatic immunity. Precision Wein-Bridge filters and carefully designed summing amplifiers combine to provide extremely accurate response, low noise, negligible distortion, and complete immunity to magnetic fields. All filters exhibit true constant "Q" response with no broadening near the "flat" setting. High slew-rate circuitry throughout the signal path results in clean, quiet, transparent sound. The faders used are a custom-manufactured metal-shaft type, with molded saddle knobs, for the ultimate in reliability and smooth "feel". Ashly's unique "T-Beam" front panel construction eliminates interconnections between the faders and the filters, resulting in a very rugged and rigid front panel.

Input and output connections include barrier strip terminals and 1/4" TRS phone jacks, as well as standard locking XLR's. Circuit ground may be lifted from chassis ground via the barrier strip. Ashly's servo-balanced output circuitry maintains unity gain even if pins 2 or 3 are connected directly to ground. Our transformer and power supply design result in lower hum noise and even greater line voltage range. In fact, these units still meet specifications when voltage drops down to as low as 93 VAC, making them the ideal choice when power stability presents a problem to the installer.
