manual abstract
III Extreme accuracy and ease-of-use, combined with Ashly's I renowned clean, straightforward 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 channels of 2/3-octave, 15-band equalization and features a peak-indicating LED, a fixed, switchable 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 subsonic 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 signal path, turn out a clean and virtually noiseless, transparent sound. A unique summing system, with low-noise amplifiers, is utilized, allowing minimum ripple and filter interaction. At the detented "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 filters are vastly superior to typical R-L-C and simulated inductor types. Constructed of precision metal-film resistors and polyester capacitors, they produce an ideal curve shape and precise center frequencies 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.
