Our flagship model combines exceptional phono preamp performance with three additional aux level audio inputs, then adds an variable output level control. Soft-touch switches control power on/off and source selection. While off, the TC-754 even remembers what source was last selected and reselects it when powered back up. The output level control allows connection to a power amp either directly or through an equalizer; or it can simply be used to fine tune the audio level sent to your computer sound card or receiver. Spectacular RIAA equalization accuracy and a S/N ratio of 85dB make the TC-754 our best performing phono preamp; its additional features are extra icing on the cake!. Now includes our improved REGULATED AC power supply usable worldwide!
