DBX 231 Dual Channel 31-Band Graphic Equilizer Pro Audio EQ

Description

The 231 dual-channel graphic equalizer is designed for precise sound shaping in professional PA systems, live events, studios and installed audio setups. It provides two independent 31-band channels with 1/3-octave constant-Q frequency bands, giving you detailed control over the audio spectrum and allowing unwanted frequencies to be adjusted with accuracy. Each frequency band offers selectable boost or cut ranges of ±6 dB or ±12 dB. A front-panel bypass switch makes it easy to compare the processed signal with the original audio, while the switchable 50 Hz low-cut filter helps reduce unwanted low-frequency rumble. The input gain control provides a ±12 dB adjustment range for convenient level matching. For flexible system integration, the unit includes balanced XLR and 1/4-inch TRS inputs and outputs. It delivers an extended frequency response up to 50 kHz and a dynamic range greater than 108 dB, helping maintain clean and detailed audio performance. Built into a rugged 2U rack-mount chassis, this dual-channel equalizer is suitable for demanding professional audio environments. It is a practical choice for DJs, live sound engineers, churches, studios, event venues and PA installations that require accurate and reliable equalization.
