Yamaha graphic equalizers incorporate active filters to provide minimum phase shift and smooth response at any boost or cut setting. The Q2031B offers 31 equalization bands at 1/3 octave intervals from 20Hz to 20kHz.
Switchable EQ gain of +/- 6dB or +/-12dB provides with a broad range, or a narrow, more precise scope of control. The +/-12dB range offers wide-range control, essential for broad range tonal variation or feedback control. The +/-6dB range provides fine control within a narrower range, well suited for acoustic tuning & subtle response shaping.
The 2U-size Q2031B offers completely independent 2-channel control from input to output with separate 31 band equalization & variable high pass filters for each channel.
The Q2031B provides quiet operation with less than 0.05% total harmonic distortion; noise is kept to a minimum with levels better than -96dB. Yamaha equalizers supply smooth, natural sound that is even compatible with digital sources.
