The Yamaha Q2031A is a professional, dual-channel 31-band graphic equalizer designed for precision audio control in studios, live sound rigs, and broadcast applications. Known for its rugged build, it divides the frequency spectrum into 1/3-octave intervals (ISO standard 20 Hz to 20 kHz) to allow detailed tonal shaping and feedback control.

Key Features

• Dual Independent Channels: Provides completely separate left/right equalization, high-pass filtering, and bypassing.
• Selectable Boost/Cut Range: Features a range switch on each channel to toggle between ± 12 dB or ± 6 dB for either drastic tone-shaping or ultra-fine tuning.
• High-Pass Filters: Includes variable roll-off controls for each channel (adjustable from 20 Hz to 200 Hz at 12 dB/octave) to eliminate low-end rumble.
• Flexible Connectivity: Equipped with both balanced XLR and standard 1/4-inch (TRS/TS) input and output jacks for easy integration with pro-audio and consumer gear.
• Monitoring & Protection: Includes peak LED indicators that light up 3 dB before clipping, along with a built-in automatic muting circuit to prevent speaker-damaging power-on thumps.
• Form Factor: Built in a durable, road-ready 2U metal chassis intended for standard 19-inch equipment rack
