Graphic equalization is indispensable for response control in a wide range of audio applications. If you need one or more stand-alone graphic EQ units, the Yamaha Q2031B is an outstanding choice that delivers professional quality with versatile control and outstanding audio performance. Use the Q2031B for live sound, recording, A/V production, electronic musical instruments, broadcasting, music listening, or any other application that requires precise response tailoring.

The Q2031B features two independent channels of graphic EQ with full 31-band control over the 20Hz to 20kHz range.

Versatile EQ Control

The Q2031B offers 31 equalization bands at 1/3 octave intervals from 20 Hz to 20 kHz. It incorporates specially designed active filters that provide minimum phase shift and smooth response at any boost or cut setting.

Range Switches

Selectable ±6 dB or ±12 dB EQ ranges offer extra control versatility. The ±12 dB range offers wide-range control that can be useful for broad tonal variation or feedback control, while the ±6 dB range provides fine control over a narrower range for acoustic tuning and subtle response shaping.

Outstanding Audio Performance

A graphic equalizer’s main function is to modify frequency response without adding unwanted distortion or noise. The Q2031B features exceptionally quiet operation with less than 0.05% total harmonic distortion. Noise levels are maintained below -96 dB, with a smooth, natural sound that is compatible with digital sources.

Variable High Pass Filters

High pass filters are useful in minimizing low-end boominess, AC hum, wind noise … generally preventing subsonic components from muddying the sound as well as wasting amplifier power. The Q2031B incorporates continuously variable high pass filters on both channels, providing 12dB/octave roll-off below any frequency from 20 Hz to 200 Hz.

Peak Indication and Muting

Independent peak indicators for each channel light when the output signal reaches 3 dB below clipping. An automatic muting circuit mutes the equalizer’s output for approximately 3 seconds after the power is switched on, to prevent transients from damaging amplifiers and speaker systems.

Acoustic Tuning

Graphic equalization is the standard method for fine tuning a sound system to match the acoustics of a studio, concert hall, or any other acoustic environment. It can be utilized to compensate for acoustic irregularities in rooms that were not designed for music listening, and deliver optimum response in properly designed studios or halls.

Feedback Control

In situations where size and placement restrictions make a feedback-proof setup impossible, a graphic equalizer can be used to reduce the gain at problem frequencies in order to minimize the possibility of feedback.

Sound Shaping

Graphic equalizers are also creative tools that can shape the sound of an instrument or voice to achieve a better blend in the mix. Added to reverb, EQ can be used to simulate a wide range of acoustic environments.

Noise Suppression

Graphic equalization can effectively minimize tape hiss, stage rumble, wind noise, microphone popping, excessive sibilance, and other sources of unwanted noise.
