• Features
  
  
• Dual channel graphic equalizer with active filters to provide minimum phase shift and smooth response at any boost or cut setting
• Switchable EQ gain of +/-6dB or +/-12dB. The +/-12dB range offers wide-range control, essential for broad range tonal variation or feedback control. The +/-6dB range provides fine control well suited for acoustic tuning and subtle shaping
• Continuously variable (20Hz to 200Hz) high-pass filters on both channels providing 12dB per octave rolloff below the desired frequency
• Independent peak indicators light when the output signal level reaches 3dB below clipping
• Automatic circuit mutes the equalizer’s output for approximately three seconds after the power is switched on, to prevent transients from damaging amplifiers and speaker systems
• EQ ON/OFF switches provide easy comparison between equalized and unequalized sound
• Suitable for fine tuning a sound system to match the acoustics of a studio, concert hall, or any other sound environment
• Can be used as a creative tool for shaping the tone of the instrument or voice to achieve a better blend in a mix. When added to reverb, EQ can electronically simulate a wide range of acoustic environments
