Note
If speaker input wires from a headunit are con-
nected to this amplifier, the amplifier will automa-
tically turn on when the headunit is turned on.
When the headunit is turned off, the amplifier
turns off automatically. This function may not
work with some headunits. In such cases, make
sure that the CH A Left channel is connected cor-
rectly. If the function still does not work, please
use a system remote control wire (sold sepa-
rately). If multiple amplifiers are to be connected
together synchronously, connect the head unit
and all amplifiers via the system remote control
wire.
