Affordable, professional-quality EQ THAT PERFORMS!

Does your vocalist sound like she's had some nasal cavity work done recently? Does your stage piano sound like it's being played from the bottom of a swamp? Does your guitar mic shriek and scream more than... well, your guitar? Everyone knows that a graphic equalizer's main function is to shape sound without adding unwanted distortion or noise. But it's also a sad fact that sometimes this really important piece of equipment, designed to make you sound better, can actually become a big headache of its own. These three EQs from Yamaha do what EQs are supposed to do - clean up your sound and stay out of your way.

The GQ1031C is a mono EQ with 31 equalization bands at 1/3 octave intervals from 20Hz to 20kHz. It does a great job of removing all the extra little sonic litter that can creep into your sound during live performance. Of course, the GQ1031 comes with the EQ staple features of highpass filter, balanced I/O, Peak indicators, and Bypass button.

For a great graphic EQ, they don't get much better than the GQ2015A, a stereo EQ that's simple, easy-to-use, and packed with power. Since it's stereo, you can use it to control your entire mix or separately treat two individual sources. Imagine, 2-channel stereo versatility, all in a slim 1U-size. The GQ2015A offers equalization bands per channel at 2/3 octave intervals from 25Hz to 16kHz. All the EQ essentials are there, including highpass filter, balanced I/O, and bypass switch.

The Q2031B is a dual channel, 4-band graphic equalizer that gives you a smooth, clean sound without any hassles. Providing quiet operation with less than .05% total harmonic distortion and noise levels better than -96dB, you can be sure your signal is pure. The Q2031 offers 31 EQ bands per channel t 1/3 octave intervals from 20Hz to 20Khz, highpass filter, balanced I/O, sensitive peak indicators, and bypass button.

Yamaha Q2031B

I've had a total of four of these units. I sold the first two I bought and regretted that I sold them and did'nt keep one. I ended up buying two more and I plan on selling one and for sure I'm gonna keep one. Great sounding units. YAMAHA for life!!!!

Typical great Yamaha quality

I actually own the older (2 separate EQs) GC1031, but they are pretty much the same. Solidly built, I never had a single problem with them in 20 years. These are in a class WAY above the low-end Alesis and Behringer. My only gripe was a slight bit of hum could be heard sometimes at loud levels - but mine were unbalanced with long cable runs sometimes. No doubt this 2031B unit (with balanced inputs) won't have that problem. Buy it - it's worth every penny and will last you a lifetime.
