lower) in parallel to achieve a 2 Ohm (or
lower) bridged mode (Diagram B).
Amplifier damage, smoke, and overheating
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-channel
amplifier, follow the speaker output con-
nection 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.
Setting the Unit
Gain Control
If the sound level is too low, even when
the volume of the car stereo used along
with this power amplifier is turned up,
turn gain control on the front of the
power amplifier clockwise. If the sound
distorts when the volume is turned up,
turn the gain control counter-clockwise.
• When using with an RCA equipped car
stereo (standard output of 500 mV), set to
the NORMAL position. When using with
an RCA equipped Pioneer car stereo with
max. output of 4 V or more, adjust level to
match the car stereo output level.
• If you hear too much noise when using the
speaker input terminals, turn the gain
control counter-clockwise.
Power Indicator
The power indicator lights when the
power is switched on.
BFC (Beat Frequency Control) Switch
If you hear a beat while listening to an
AM broadcast with your car stereo,
change the BFC switch using a small
standard tip screwdriver.
LPF (Low-Pass Filter) Select Switch
Set the LPF select switch as follows according to the type of speaker that is connected to the
speaker output connector and the car stereo system:
