Frustrated by the lack of inputs on your minisystem or home theatre receiver? Tired of having to unplug your TV audio or MP3 player whenever you want to play or record an LP? This phono preamp is for you. Functionally the same as our TCC TC-400 preamp, this model adds an AUX level input to replace the one it connects to on your stereo, allowing either your turntable or whatever usually occupies your stereo's aux input to be selected at the push of a switch, without disconnecting or rearranging wires.
