EQ-231 31-Band Dual-Channel Stereo Graphic Equalizer — ±12dB Bands, LOW-CUT & BYPASS, XLR + 1/4" TRS I/O, 4-Segment LED

EQ-231 professional dual-channel stereo graphic equalizer built for audiophiles, DJs and studio/live environments. Each channel provides 31 bands with an adjustable range of ±12dB per band, giving detailed tone shaping across the full spectrum. Adjust gain and decay values from +/-6dB to +/-12dB for precise control over response and smoothing. A LOW-CUT switch removes unwanted low-frequency artifacts like wind noise, floor rumble and electrical hum to deliver cleaner, tighter low end. For quick troubleshooting and A/B comparisons a BYPASS switch is included, while 4-segment LED ladders display gain reduction and output levels for clear visual monitoring. The unit supports XLR balanced and 1/4" TRS unbalanced inputs and outputs to work with a wide variety of audio setups. Suitable for live applications, audio installations, and studio use.
