Connecting the units
Do not install or use this amplifier by wiring
speakers rated at 2 W (or lower) in parallel to
achieve a 1 W (or lower) bridged mode (Dia-
gram B).
Amplifier damage, smoke, and overheating
could result from improper bridging. The am-
plifier surface could also become hot to the
touch and minor burns could result.
To properly install or use a bridged mode and
achieve a 2 W load, wire two 4 W speakers in
parallel with Left + and Right * (Diagram A)
or use a single 2 W speaker.
In addition, refer to the speaker instruction
manual for information on the correct connec-
tion procedure.
For any further enquiries, contact your local
authorized Pioneer dealer or customer
service.
