Outstanding Audio Performance

A graphic equalizer’s main function is to modify frequency response without adding unwanted distortion or noise. The Q2031B features exceptionally quiet operation with less than 0.05% total harmonic distortion. Noise levels are maintained below -96 dB, with a smooth, natural sound that is compatible with digital sources.

/div.imageDescriptionA03

Variable High Pass Filters

High pass filters are useful in minimizing low-end boominess, AC hum, wind noise … generally preventing subsonic components from muddying the sound as well as wasting amplifier power. The Q2031B incorporates continuously variable high pass filters on both channels, providing 12dB/octave roll-off below any frequency from 20 Hz to 200 Hz.

Acoustic Tuning

Graphic equalization is the standard method for fine tuning a sound system to match the acoustics of a studio, concert hall, or any other acoustic environment. It can be utilized to compensate for acoustic irregularities in rooms that were not designed for music listening, and deliver optimum response in properly designed studios or halls.

/div.desc

/div.imageDescriptionA03

Feedback Control

In situations where size and placement restrictions make a feedback-proof setup impossible, a graphic equalizer can be used to reduce the gain at problem frequencies in order to minimize the possibility of feedback.

/div.desc

/div.imageDescriptionA03

Sound Shaping

Graphic equalizers are also creative tools that can shape the sound of an instrument or voice to achieve a better blend in the mix. Added to reverb, EQ can be used to simulate a wide range of acoustic environments.

EQ RANE DEQ60L เครื่องปรับแต่งเสียงแบบสเตอริโอ ข้างละ 30 band ก้านสไลด์ยาว 1/3 octave graphic equalizer with Perfect-Q and Proportional-Q filtering

The term “graphic equalizer” refers to a device that allows a user to “draw” the desired frequency response using slider controls on the unit’s front panel. However, the physics of filter designs has meant that the end result was essentially a compromise, an approximation, as adjacent bands would to some degree or other interact. The 45mm slider DEQ 60L and the 25mm slider DEQ 60from Rane solve this problem.

Using Digital Signal Processing (DSP) Rane has developed a filter design that exhibits virtually no band interaction and extremely low ripple between adjacent bands. Called Perfect-Q, the result is the first graphic equalizer whose output response precisely matches slider settings. For those users who want to use a more traditional filter response, each channel of the DEQ 60L is selectable between Perfect-Q or Proportional-Q response.

In addition to the unique filters, the DEQ 60L features high and low pass filters, input and output level adjustment, a choice of boost/cut range (+/-12dB or +/-6dB) or cut-only mode, the ability for each channel to use either the A or B channel controls and multiple connectivity options. A bypass switch and bypass relay and a universal switching power supply make this unit a truly professional product.

Features:

• Dual channel 30 band 1/3 octave graphic equalizer with Perfect-Q and Proportional-Q filtering
• No EQ filter interaction when in Perfect-Q mode
• Analog controlled DSP
• Independent “Accelerated-Slope” 3-band full-cut tone controls
• Each channel may use the A or B channel controls
• Selectable Boost/Cut +/-12dB or +/-6dB and a cut-only mode
• 45mm sliders with soft-touch knobs
• Variable input and output level control
• Eight segment metering for each Input and Output
• Active balanced input and output connections

อีคิว EQ DBX 2231V 2×31 Band Graphic Equalizer/Limiter with Type III™ Noise Reduction in-circuit at the push of a button. Increases S/N ratio by up to 20dB

It’s amazing. One little button. It has so much effect. The 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 EQ’s possible, boxes with the heritage and performance to rival our famous 30 Series EQ’s. 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 EQ’s 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 EQ’s they wanted something that would be unique to these EQ’s. 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 0 to +20dbu, the 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 EQ’s. 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 EQ’s at your pro audio outfitter. You’ll see, with the 20 Series EQ’s you get both MORE

Features:

• Revolutionary instant encode/decode Type III® Noise Reduction in-circuit at the push of a button. Increases S/N ratio by up to 20dB
• Patent-pending PeakPlus™ Limiter threshold range from 0dBu to +24dBu (off) can transparently tame the wildest hits or the subtlest nuances of any signal
