Seems to be fully working. Ive had no issues with it. I used it with multiple subwoofer optimizer software and subwoofers as well as a crossover for active speakers. Left it on and never had any issues with it doing what its supposed to. I’ll stash it away for later use if no one wants it for a reasonable price. Currently I have a new A/V processor and am not using it. Comes with remote, power transformer/cable and usb cable.
