Sony SB-V1000 Video/Audio selector unit. Very cool unit with front audio level meter. I used it to switch between multiple CD players. However, at least one of the inputs didnt work and maybe at least one of the output channels didnt work. I was able to use it as it is but I found another one fully functional so selling this one STRICTLY AS-IS, FOR PARTS, NOT WORKING. NO RETURNS, NO REFUNDS. See my 100% positive feedback... Thanks!
