The B-21S is an input module for use with TOA 900 series amplifiers. It has a screw terminal connector and supports balanced or unbalanced line level signals from devices such as CD players, tape decks, or AM/FM tuners. The unit is transformer-isolated to minimize ground loop problems when connected to remote equipment. The B-21S allows remote control of the output signal using an external potentiometer. Simply plug the B-21S into the module slot on your 900 series amplifier and you're ready to go.
