Auto-equalizing mike jack

Pull the auto-equalizing mike jack out of the

console box, so that the mike can be plugged

in or pulled out even after this unit has been installed.

Install the power box cord

securely so that the cord can not

be easily pulled out.

Note:

• This unit is for vehicles with a 12-volt battery and

negative grounding. Before installing it in a recre-

ational vehicle, truck, or bus, check the battery

voltage.

• To avoid shorts in the electrical system, be sure to

disconnect the ≠battery cable before beginning

installation.

• Refer to the owner’s manual for details on con-

necting the power amp and other units, then make

connections correctly.

• Secure the wiring with cable clamps or adhesive

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, handbrake,

and seat rails. Do not route wiring in places that

get hot, such as near the heater outlet. If the insula-

tion of the wiring melts or gets torn, there is a dan-

ger 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 battery. This

will damage the lead insulation and cause a very

dangerous short.

• Do not shorten any leads. If you do, the protection

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.

• Since a unique BPTL circuit is employed, never

wire so the speaker leads are directly grounded or

the left and right ≠speaker leads are common.

• If the RCA pin jack on the unit will not be used, do

not remove the caps attached to the end of the con-

nector.

• Speakers connected to this unit must be high-

power types with minimum rating of 50 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 catch-

ing fire, emitting smoke, or becoming damaged.

• When this product’s source is switched ON, a con-

trol signal is output through the blue/white lead.

Connect to an external power amp’s system remote

control or the car’s Auto-antenna relay control ter-

minal (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 disconnected

lead with insulating tape. Especially, insulate the

unused speaker leads without fail. There is a possi-

bility of short-circuiting if the leads are not insulat-

ed.

• To prevent incorrect connection, the input side of

the IP-BUS connector is blue, and the output side

is black. Connect the connectors of the same colors

correctly.

• If this unit is installed in a vehicle that does not

have an ACC (accessory) position on the ignition

switch, the red lead of the unit should be connected

to a terminal coupled with ignition switch ON/OFF

operations. If this is not done, the vehicle battery

may be drained when you are away from the vehi-

cle for several hours. (Fig. 1)

• The black lead is ground. Please ground this lead

separately from the ground of high-current prod-

ucts such as power amps.

If you ground the products together and the ground

becomes detached, there is a risk of damage to the

products or fire.
