GQ-231

I hen Ashly set out to design the

GQ-Series, we first thoroughly

re-examined the accepted prin

ciples of graphic equalization.

Extreme accuracy and ease-

of-use, combined with Ashly's

renowned clean, straightfor

ward engineering and design, produce a

series of graphic equalizers that can truly

be called the "next generation."

There are three models available in the

GQ Series. The GQ-215 offers two chan

nels of 2/3-octave, 15-band equalization

and features a peak-indicating LED, a

fixed, swifchable 40Hz subsonic filter,

and a cut or boost range of ±15dB. The

GQ-131 is a mono 1/3-octave, 31-band

equalizer, incorporating a switchable sub

sonic filter that is tunable between 8Hz

and 200Hz, and a boost or cut range of

either ±6dB or ±15dB. Additionally, a nine

position, three color LED level meter and

a peak-indicating LED are provided for

visual reference. The GQ-231 has two

separate channels of 1/3-octave, 31-band

equalization, each incorporating the same

features as the GQ-131.

Ashly's innovations in the GQ-Series

are numerous: New Op-Amps, with high

slew-rate circuitry for the length of the sig

nal path, turn out a clean and virtually

noiseless, transparent sound. A unique

summing system, with low-noise ampli

fiers, is utilized, allowing minimum ripple

and filter interaction. At the detected "flat"

center position, the filters go off-circuit for

an extremely accurate flat response and

absolute minimum noise. There is no

broadening at all near the flat setting.

Our new Q-enhanced Wein-bridge fil

ters are vastly superior to typical R-L-C

and simulated inductor types. Construct

ed of precision metal-film resistors and

polyester capacitors, they produce an

ideal curve shape and precise center fre

quencies with low distortion.

Finally, a unique T-beam front panel

construction eliminates interconnections

between the faders and filters, resulting in

a graphic equalizer with genuine Ashly

innovation, reliability and sonic quality.

The GQ Series, like all Ashly products, is

now fully covered by our exclusive five-

year worry-free warranty.
