Hybrid S-EQ231A – 31-Band Stereo Graphic Equalizer with Sub Output

Powerful 31-band stereo EQ with selectable ±6/12dB gain, subwoofer crossover output, and full balanced I/O for precise system tuning and frequency control.

The Hybrid S-EQ231A is a professional-grade 31-band stereo graphic equalizer designed for precise audio system tuning, whether in live sound reinforcement or studio environments. Each channel features 31 adjustable bands with switchable ±6dB or ±12dB gain via 20mm smooth-sliding faders. Built for both control and clarity, the unit also includes a low-cut switch for filtering unwanted sub-rumble and a bypass function for quick A/B comparison.

A unique addition is its dedicated Sub-Out with adjustable crossover control (30Hz–200Hz), effectively allowing the S-EQ231A to serve as a basic active crossover for subwoofer integration. This makes it ideal for DJs, bands, AV installations, and mobile sound professionals needing precision tone shaping and flexible routing.

Balanced XLR and ¼” TRS input/output connectors ensure reliable signal transmission, while the internal power supply and rugged rack-mount design (2U height) make it road-ready and installation-friendly.
