Behringer GEQ3102 Ultra Graph Pro 31-Band EQ

This is a great unit. My wife bought it for me for my birthday thinking it was a mobile audio accessory - and of course it's not ... but that's OK. I just don't have a need for another home EQ. Brand new, in the box, all manuals, etc.

First $140 OBO takes it - I'll pay for shipping.

31-band stereo graphic equalizer for live and studio applications
Sound improvement in post-production and all recording situations
Sweep-able high-pass and low-pass filters remove unwanted signal portions, i.e. impact noise, tape hiss, etc.
Servo-balanced inputs and outputs with gold-plated XLR and 1/4" TRS connectors
Relay-controlled hard bypass switch with auto bypass function (safety relay)
Extremely low-noise operational amplifiers for outstanding audio quality
Illuminated high-precision Alps faders
12-segment LED display for input or output level
High-quality components and rugged construction for long life
Manufactured under ISO9000 certified management system
