1215 Dual 15-Band Graphic Equalizer

The dbx 12 Series were designed to meet the needs of the most
demanding sound reinforcement environments, while offering the
simplicity of straightforward controls. The 1215 provides standard
features like dual channels, 15 2/3 octave bands, ISO frequency
centers, +/-12 dB input gain range, and switchable 40Hz/18 dB per
octave low-cut filters, but also includes other thoughtful features.
These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut
range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS
connectors for installation ease; balanced inputs and outputs for quiet
operation; and chassis/signal ground lift capabilities for quick hum isolation.
The visionary design of the dbx 12 Series makes your job easier.

The dbx 12 Series Equalizers were precision engineered to provide years
of maintenance-free operation in any application. The magnetically isolated
transformer, electronically balanced/unbalanced inputs and servo balanced/
unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire
relay bypass with 2 second power up delay were steps our engineers took
to ensure compatibility for all installations. Only the best components were
utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR
(ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel
crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail
is contained in a 2U steel/aluminum chassis.

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!!!
