Before Using This Product
CAUTION
• Never replace the fuse with one of greater
value or rating than the original fuse. Use of
an improper fuse could result in overheating
and smoke and could cause damage to the
product and injury including burns.
• Use the supplied hexagonal wrench to tight-
en screws when fastening wires to the termi-
nal. The use of a long, commercially avail-
able hexagonal wrench can cause excessive
torque to be applied possibly resulting in
damage to terminals and wires.

CAUTION
Do NOT install or use your Pioneer ampli-
fier by wiring speakers rated at 4 Ohm (or
lower) in parallel to achieve a 2 Ohm (or
lower) bridged mode (Diagram B).
Amplifier damage, smoke, and overheat-
ing could result from improper bridging.
The amplifier surface could also become
hot to the touch and minor burns could
result.
To properly install or use a bridged mode
for a two-channel amplifier and achieve a
4 Ω load, wire two 8 Ω speakers in parallel
with Left + and Right – (Diagram A) or
use a single 4 Ω speaker. For a four-chan-
nel amplifier, follow the speaker output
connection diagram for bridging as shown
on the back of your amplifier, and wire
two 8 Ω speakers in parallel to achieve a 4
Ω load or use a single 4 Ω speaker per
channel.
If you have any questions or concerns,
please contact your local authorized
Pioneer dealer or call Pioneer customer
service.
