Notes

! If speaker wires with an RCA pin cord from a

headunit are connected to this amplifier, the

amplifier will automatically turn on when the

headunit is turned on. When the headunit is

turned off, the amplifier turns off automati-

cally. This function may not work with some

headunits. In such cases, please use a sys-
