Equalizer dbx 131s

The dbx 131s is a professional single-channel 31-band (1/3 octave) graphic equalizer that combines high-quality sound, reliability, and simple operation. With the legacy of the legendary dbx series behind it, this model is ideal for studio use, touring, and fixed installations. It features a selectable boost/cut range (±6 dB or ±12 dB), 20 mm sliders, and an intuitive front panel interface.

The dbx 131s delivers an extended frequency response (10 Hz – 50 kHz), a wide dynamic range of over 108 dB, and ultra-low distortion (<0.003%), ensuring clear and transparent audio in any environment. It also features a 4-segment LED output level meter, front panel bypass switch, and a 50 Hz low-cut filter with a 12 dB/octave slope for added flexibility.

Balanced/unbalanced XLR and 1/4" TRS inputs and outputs offer versatile connectivity with strong RF interference protection. Its compact 1U rackmountable chassis makes integration easy, while low power consumption and a universal power supply (100–240 V) make the unit highly adaptable for various applications.
