Pioneer DEH-P7300R - Manual (Page 3)

Speakers eonneeted to this unit must be high-
power types with minimum rating of 50 W and
impedanee of 4 to 8 ohms. Conneeting speakers
with output and/or impedanee values other than
those noted here may result in the speakers eateh-
ing fire, emitting smoke, or beeoming damaged.
When this produet’s souree is switehed ON, a
eontrol signal is output through the blue/white
lead. Conneet to an external power amp’s system
remote eontrol or the ear’s Auto-antenna relay
eontrol terminal (max. 300 mA 12 V DC). If the
ear features a glass antenna, eonneet to the anten­
na booster power supply terminal.
When an external power amp is being used with
this system, be sure not to eonneet the blue/white
lead to the amp’s power terminal. Likewise, do
not eonneet the blue/white lead to the power ter­
minal of the auto-antenna. Sueh eonneetion eould
eause exeessive eurrent drain and malfunetion.
To avoid short-eireuiting, eover the diseonneeted
lead with insulating tape. Espeeially, insulate the
unused speaker leads without fail. There is a pos­
sibility of short-eireuiting if the leads are not insu­
lated.
To prevent ineorreet eonneetion, the input side of
the IP-BUS eonneetor is blue, and the output side
is blaek. Conneet the eonneetors of the same eol-
ors eorreetly.
If this unit is installed in a vehiele that does not
have an ACC (aeeessory) position on the ignition
switeh, the red lead of the unit should be eonneet­
ed to a terminal eoupled with ignition switeh
ON/OFF operations. If this is not done, the vehi­
ele battery may be drained when you are away
from the vehiele for several hours. (Fig. 1)

The blaek lead is ground. Please ground this lead
separately from the ground of high-eurrent prod­
uets sueh as power amps.
If you ground the produets together and the
ground beeomes detaehed, there is a risk of dam­
age to the produets or fire.
Cords lor ihis prodiiei and those for other prod-
iiets may be dilTerent eolors even if they have the
same funetion. When eomieeting this produet to
another produet, refer to the supplied Installation
manuals of both prodiiets and eonneet eords that
have the same funetion.
