DBX 20-20


The DBX 20/20 is the world's first automatic equalizing system.

It combines a microprocessor controlled 10-band graphic equalizer, real-time analyzer, pink noise generator, sound-pressure level meter and includes a calibrated microphone.

Unlike other equalizers, the 20/20 automatically adjusts for the effects of furniture, drapes, and other acoustical factors in your room. The result is highly accurate tonal balance, realistic sound, and sharp definition of every instrument.

Simply place the microphone at any desired listening position and let the computer find the precise equalization curve, in only 15 seconds.

And because the 20/20 has ten memory locations, you can equalize each of your favorite listening positions, then store them for later recall.

The 20/20 will even average several listening positions automatically for the best frequency response over a wide listening area.

Some of the advanced features of the 20/20 include LED readouts on all ten bands, precision switches instead of the traditional slide controls for manual adjustment, and a high-frequency roll off curve that automatically simulates the frequency response of a music hall.

The DBX 20/20 is the state-of-the-art in equalizers, and a must for anyone who is truly serious about high fidelity.
