SPECIAL NOTE: This Booster has been designed to be connected to units which incorporate BTL (Balanced Transformer-Less) circuitry or to common-ground type. (Many boosters can not be connected to BTL-type circuits without damage.) However, it is vital that you properly identify input and output wires and that you do not interconnect "Ground" or "Negative-side" speaker wires. If you are not sure how to connect a booster to your existing unit(s), we strongly recommend that you have your system installed by an experienced electronics service technician. (EB 6/5/96)
