Purchased new from a major musical instrument store and used only two or three times, so it's practically new. I bought it intending to use it for sound work, but I never had the opportunity and it's been stored in its box. It's not something that appears often in the used market, so please consider this opportunity. I'm selling it to organize my equipment. All accessories are included. I can wrap the outer box in air cap and ship it immediately. This is a standard model for feedback suppressors. The 2-channel feedback suppressor, equipped with 24 filters per channel, features cutting-edge feedback removal technology and is very simple and intuitive to operate. The minimum 1/60 octave notch filter can be selected from fixed or live mode and can also be used as a PEQ. It supports a wide range of applications, and is especially effective in live PA, events with many performers unfamiliar with microphones, and other similar situations. Automatically detects feedback frequencies and removes feedback by placing up to 20 filters on each channel, for a total of 40 filters. Equipped with a PANIC button to forcibly execute feedback detection in response to sudden feedback. In auto mode, it constantly monitors the signal and automatically places filters when feedback occurs. In manual mode, 20 parametric EQs can be set arbitrarily.
