Dual 31-Band Channels: Two independent channels providing 1/3-octave control across standard ISO frequencies from 20 Hz to 20 kHz. Control Sliders: Non-conductive 20mm faders that allow you to boost or cut specific frequencies to match room acoustics. Gain & Boost Range: Includes a selectable boost/cut range of either ±6 dB or ±12 dB for precise adjustments or broader tonal shaping. Low-Cut Filter: Features a built-in 50Hz low-cut (high-pass) filter per channel with a 12 dB/octave slope to remove unwanted low-end rumble or stage vibration.
