I bought this from Soundhouse a few years ago. I've confirmed that it works without any problems. Thank you. Specifications: ■ Audio/Video Direct Box ~From the manufacturer's website~ This is a direct box for AV equipment that converts stereo audio equipment such as iPods, laptop PCs, CD players, and DVD players into balanced mono outputs at microphone level. In addition to RCA, 1/4" and 1/8" TRS line level inputs, it can also accept speaker level signals (100W @ 8Ω mono) (1/4" and speaker terminals).
