TAPCO TWEEQ T-231 2X31 BAND GRAPHIC EQ

Built to Tweak.
The Tweeq T?231 is a 2-channel 31-band graphic equalizer that allows you to "tune" your
live sound setup to sound best in any given space. This instrument provides fine control of
31 frequency bands?giving you the power to "shape" your sound with exceptional precision.
Whether you're running live sound or enhancing an installed system, you can count on Tweeq's
bulletproof construction, quality sliders, and great sound quality at a price that just might allow
you to buy two.
Why should you Tweeq?
Your average car or home stereo typically provides bass and treble controls to let you tune your
system to your particular taste. The Tweeq T?231 works in a similar way, but offers much finer
control via 31 separate precision slide controls that boost or cut specific frequencies, ranging from
the lowest bass to the highest treble frequencies. While you can certainly use the T?231 to fine-tune
a PA system to suit your particular tonal preferences, it's most powerful as a tool for correcting issues
like muddy sounding loudspeakers or annoying feedback from stage monitors.
What's to Tweeq?
The T?231 features dual-channel stereo operation with precision sliders for fine control of your audio.
It's designed with constant Q filters for superior sonic performance at 1/3-octave intervals across the
entire range of frequencies normal human beings, drummers and DJs can hear. In addition, both channels
offer variable high and Low Pass Filters for removing unwanted upper and lower frequencies from your
sound, a 6 or 12 dB Range switch for gross- or fine tuning, bright four-segment LED metering, Output
gain control, and a Bypass switch for quick A/B comparisons. And forget the adapters because the
Tweeq T?231 provides RCA, balanced/unbalanced ?-inch and balanced XLR connections for both inputs
and outputs.
Tough, so you don't have to be
Fortunately for you road dogs, the Tweeq T?231 is compact - filling just two spaces in your standard 19-inch
rack-mount road case. It has a switchable 115V/230V power supply in case you're traveling across borders,
and it's designed to be tough enough to withstand the punishing rigors of the road while continuing to perform
set after set, night after night, year after year.

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!!!
