The GQX-3101 is a single-channel,
thirty-one band, 1/3 octave graphic EQ. It offers a tunable high-pass filter
circuit from 8Hz to 200Hz and a 10-segment, two color LED meter display
referencing 0 VU to +4dBu and a switch-selectable cut or boost of either
6dB or 15dB
The GQX-3101 is 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.
The 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.
