Connecting the Units

Note:
• This unit is for vehicles with a 12-volt battery
and negative grounding. Before installing it in a
recreational vehicle, truck, or bus, check the
battery voltage.
• To avoid shorts in the electrical system, be sure
to disconnect the · battery cable before begin-
ning installation.
• Refer to each product's manual for details on
connecting the power amp and other units, then
make connections correctly.
• Secure the wiring with cable clamps or adhe-
sive tape. To protect the wiring, wrap adhesive
tape around them where they lie against metal
parts.
• Route and secure all wiring so it cannot touch
any moving parts, such as the gear shift, hand-
brake and seat rails. Do not route wiring in
places that get hot, such as near the heater out-
let. If the insulation of the wiring melts or gets
torn, there is a danger of the wiring short-
circuiting to the vehicle body.
• Don't pass the yellow lead through a hole into
the engine compartment to connect to the bat-
tery. This will damage the lead insulation and
cause a very dangerous short.
• Do not shorten any leads. If you do, the protec-
tion circuit may fail to work when it should.
• Never feed power to other equipment by cutting
the insulation of the power supply lead of the
unit and tapping into the lead. The current
capacity of the lead will be exceeded, causing
overheating.
• When replacing fuse, be sure to use only fuse of
the rating prescribed on the fuse holder.
• If the RCA pin jack on the unit will not be used,
do not remove the caps attached to the end of
the connector.

• Since a unique BPTL circuit is employed, never
wire so the speaker leads are directly grounded
or the left and right · speaker leads are com-
mon.
• Speakers connected to this unit must be high-
power types with minimum rating of 45 W and
impedance of 4 to 8 ohms. Connecting speakers
with output and/or impedance values other than
those noted here may result in the speakers
catching fire, emitting smoke or becoming
damaged.
• When this product's source is switched ON, a
control signal is output through the blue/white
lead. Connect to an external power amp's sys-
tem remote control or the car's Auto-antenna
relay control terminal (max. 300 mA 12 V DC).
If the car features a glass antenna, connect to
the antenna booster power supply terminal.
• When an external power amp is being used with
this system, be sure not to connect the
blue/white lead to the amp's power terminal.
Likewise, do not connect the blue/white lead to
the power terminal of the auto-antenna. Such
connection could cause excessive current drain
and malfunction.
• To avoid short-circuiting, cover the disconnect-
ed lead with insulating tape. Especially, insulate
the unused speaker leads without fail. There is a
possibility of short-circuiting if the leads are not
insulated.
• To prevent incorrect connection, the input side
of the IP-BUS or optical cable connector is
blue, and the output side is black. Connect the
connectors of the same colors correctly.
