ASHLY GQX 3102 – Graphic Equalizer Stereo 31-Band

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.

DBX 2215 Dual 15-Band Graphic Equalizer with Noise Reduction

 It's amazing. One little button. So much effect. dbx? Type III? Noise Reduction is an entirely new concept... virtually instantaneous encode/decode within the circuitry of the box. We started out to build the finest EQs possible, boxes with the heritage and performance to rival our famous 30 Series EQs. And to no one's surprise they came out awfully darn good. (Ask to see the Audio Precision plots compared to the competition.) But then, Roger (our chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this new noise reduction stuff in the box. We listened to it and were amazed. The EQs sounded great without it but with it the performance was nothing short of incredible. Check it out yourself and see.

But hey, Roger wasn't about to stop there. PeakPlus? Limiter. Who knows more about limiting than the folks at dbx; nobody... that's who. So when the guys were developing this new series of EQs they wanted something that would be unique to these EQs. That's when Roger got another one of his bright ideas and said "I bet they'll work a lot better if there's a cool limiter built in." Next thing you know, all the guys are in the studio amazed at the new limiter Roger had designed specially for the 20 Series. Once again, hearing is believing... With a threshold range of 0dbu to plus 20dbu, the patent-pending PeakPlus limiter is designed to tame your program material from the subtlest nuances to the rowdiest hits. Also, the four stage LED ladder gives you a great visual indication as to what the limiter is doing.

20 Series EQs. You used to have to settle for second best in a reasonably priced EQ but not any more. With the new 20 Series from dbx Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III Noise Reduction. Check out the dbx 20 Series graphic EQs at your pro audio outfitter. You'll see, with the 20 Series EQs you get MORE!!!
