DBX 2231 EQ/Limiter

Dual 31 band graphic EQ with noise reduction and limiter.

In good condition - was part of a pa system for one venue and lived there until system upgrade.

FUNCTION SWITCHES
Type III® NR: Activates dbx Type III Noise Reduction
EQ Bypass: Bypasses the Graphic Equalizer section in the signal path
Low Cut (recessed): Activates the 40Hz 18dB/octave Bessel high-pass filter
Range (recessed): Selects either +/- 6dB or +/-15dB slider boost/cut range
