available in black or silver finish; this is the BLACK VERSION 4 pair of RCA jacks, 2 stereo 3.5mm jacks record and play simultaneously; each port is independently switchable all connectors are gold-plated passive device, no power required Now available in either BLACK or SILVER finish! This model allows you to connect up to five stereo aux level sources to one input. One or five or any combination in between can be selected to mix and play at once. Unused inputs can be "reversed" and used as outputs to additional amps or recording devices. Four jack sets are RCA type; the remaining two are 3.5mm stereo mini-jacks (the kind found on Discmen and MP3 players). Note that this product contains no amplifier, so you cannot use its output to drive wired headphones; however wireless headphones (which have their own built-in amps) will work fine with it.
