The dbx 1231 is a 2-channel graphic equalizer for precise shaping of audio signals. It can be used to make sound adjustments and frequency corrections as well as to compensate for influences of the room acoustics on the sound.

The dbx 1231 allows processing over the entire audible frequency range. It lies between 20 Hz and 20 kHz and is divided into 31 frequency bands. A graphic equalizer has a separate slider for each frequency band. This allows you to boost or cut specific frequencies.

The sound can be quickly and easily adapted to one's own ideas. DJs or home theater enthusiasts prefer a more bass-driven sound. If, on the other hand, a very differentiated sound is desired, the dbx 1231 has a low-cut filter for lowering low frequencies. With an equalizer, however, the audio signal can also be equalized. Disturbing frequencies are removed until a pleasant linear listening impression is achieved.

Equalizers are often used to compensate for the influence of room acoustics on the sound. Due to the reflection of sound waves, some frequencies are amplified or attenuated. Especially when a sound image that is as unaltered as possible is desired, frequency correction is necessary.

The sliders of the dbx 1231 are 45 mm long and have an adjustment range of either ± 6 dB or ±15 dB. Each of the 31 frequency bands is 1/3 octave wide. The input gain on the dbx 1231 is adjustable. Quiet signals can be amplified by 12 dB or loud signals can be attenuated by 12 dB. 4 LEDs indicate the output level and if the equalizer is overdriven. Due to its wide dynamic range of 109 dB, the dbx 1231 sounds clean without overdriving even at extreme settings.
