Product Details
	•	Product: Yamaha Q2031B Graphic Equalizer
	•	Included: Yamaha Q2031B unit only
	•	Weight: 4.0 kg

Product Description

The Yamaha Q2031B is a professional dual-channel, 31-band graphic equalizer designed for precise audio frequency control. Each channel offers 31 bands at 1/3 octave intervals, covering frequencies from 20 Hz to 20 kHz. The unit features selectable ±6 dB or ±12 dB gain ranges, allowing for both subtle adjustments and more pronounced equalization. Continuously variable high-pass filters on both channels provide 12 dB per octave roll-off below any frequency from 20 Hz to 200 Hz, helping to eliminate unwanted low-frequency noise. Balanced XLR and 1/4” TRS inputs and outputs ensure compatibility with various audio systems. The Q2031B is housed in a rugged 2U rack-mountable chassis, making it suitable for both studio and live sound applications.

Specifications can be found online.
