Powerful DBX 2231 Equaliser Dual 31-Band EQ with Subharmonic Synthesiser

The DBX 2231 Equaliser is a professional dual-channel 31-band graphic equaliser designed for precise audio control and enhanced low-frequency performance in live sound and installed PA systems. Built for demanding sound reinforcement environments, it combines detailed frequency shaping with a built-in subharmonic synthesiser for powerful bass enhancement.

Each channel of the DBX 2231 Equaliser offers 31 bands of one-third octave control, allowing sound engineers to fine-tune system response with accuracy across the full audio spectrum. With ±12dB cut and boost per band, it provides detailed control for correcting acoustic issues, improving clarity, and balancing overall sound output in any venue.

A standout feature of the DBX 2231 is its integrated subharmonic synthesiser, which generates controlled low-frequency content an octave below the original signal. This adds depth and impact to bass performance, making it especially effective in club systems, live concerts, DJ setups, and large PA environments where powerful low-end reinforcement is required.

The DBX 2231 Equaliser is widely used by sound engineers seeking both precision equalisation and enhanced bass presence in a single reliable unit. It delivers consistent performance in high-energy live environments where clarity and impact are equally important.
