Dbx, Inc. is a US producer of professional audio recording equipment. It was founded by David E. Blackmer in 1971.
The company's initial objective was to "get closer to the realism of a live performance". His first products were based on the concept of using the decibel expansion that gave the company its name. Dbx is best known for the dbx noise reduction system. The dbx noise reduction system used compression when recording an audio track and a symmetrical extension during playback. They also manufactured the Model 700, a unique but short-lived studio recording system that is popular in some circles as a mastering format. Another prior product was the DeciBel eXpanded range meter, a small semiconductor meter that measured lower and stronger audio voltages than other larger contemporary voltmeters, integrated in an aluminum extrusion that was roughly The size of the meter itself.
Active filter 223 XL DBX 2-way cross-over / mono 3-way, 24 dB per octave. Inputs and outputs balanced on XLR. Outputs "low" summable mono for subwoofer. High-pass filter (low cut) 40 Hz. Phase reversal on all outputs. Individual output level control. Linkwitz-Riley filters 24 dB per octave.
Let's take a look at the construction features of the DBX 234. At first glance you will notice that the units are very beautiful, and that when you turn the control something else becomes apparent: these units are extremely well built. The controls give great precision and the feeling of solid "click" too. When you open the box you will not find an external power supply that accompanies most processors in this price range because we know how hard it can be to work with external power supplies and even if it costs a little more we put High quality power supply right into the unit.

The DBX 2231 is a 1/3 octave two-channel equalizer with 45 mm sliders. It measures 3 U of height, and quickly imposed itself like a classic in sonorisation, facade like returns. All controls on the front panel are very clear and logical. The central operating frequencies are arranged in accordance with the ISO standard, from 20 Hz to 20 kHz. Revolutionary Noise Reduction DBX TYPEIIITM capable of reducing intrinsic noise by 20 dB Exclusive dbx PeakPlusTM limitation system for added protection Selection of the efficiency range (between ± 6 dB and ± 15 dB) Symmetric inputs and outputs Connections via XLR, terminal block and 1/4 "jacks Input gain range of -12 dB / + 12 dB Low cut filter 18 dB / octave at 40 Hz type Bessel Possibility of decoupling the ground and the chassis Integrated Power Transformer
With the 2 series, DBX succeeds in maintaining the very high quality of its products, while offering a price adapted to the lowest budgets. Equalizers of the 2 series offer an input gain of +12 dB, gains or attenuations by bands switchable between +6 or +12 dB, inputs / outputs on XLR connector and on a 6.35 mm jack, faders 20 mm, intuitive user interface and full level control.Due to their amazing frequency response from 10 Hz to 50 kHz, their dynamic range of 108 dB and their toroidal transformer, the Series 2 devices represent a major step forward in improving the quality of entry-level graphics .
