INTRODUCTION
PB-601
The PB-601 utilizes 8 MOSFETS 2 TRANSFORMER in its design to produce enough
voltage to supply the main amplifier and a huge considerable amount of reserve
voltage for peak “high demand” situations.

FUNCTIONS PB-101/PB-251
1. POWER ON LED
Lights up when the remote on system is energized.
2. LOW LEVEL INPUT (HIGH IMPEDANCE)
This unit is provided with gold plated RCA input Jacks for High impedance in-
put. Couple the RCA input with the car stereo output using RCA type connector
cables.
3. GAIN CONTROL
Adjusting the control will match the output of the stereo to the amplifier. Turn
the control clockwise for more volume and counter-clockwise for less volume.
If there is distortion when the volume of stereo is turned up, turn the control down.
4. HIGH LEVEL INPUT (LOW IMPEDANCE)
If your car stereo does not have RCA output jacks, you can connect the speaker
output from the stereo system to the amplifier.
5. POWER SUPPLY
A. +12V
To connect +12V DC power supply wire from the terminal of the battery.
B. GROUND
To connect the ground wire from the chassis of the automobile.
C. REMOTE
To connect the control wire which provides remote turn on and off of the
amplifier by the radio/cassette player. (Usually The Auto Antenna Lead)
6. POWER FUSE
The power fuse protects both this amplifier and the automobile electricla system
from short circuit conditions.
7. SPEAKER TERMINALS
The speaker terminals are 14K Gold Plated for high conductivity and minimum
impedance loss. The terminals are facing upwards for easy wiring in tight situa-
tions. Be sure to strip just enough insulation off your speaker wires that will fit
under the screw plate to help ensure against speaker wire short circuit.

C. POWER CONNECTION
1. Connect the B + 12V pole of power supply directly to the battery (+) position
terminal.
2. Connect the GND pole of power supply directly to the (-) negative ground
battery terminal or car chassis.
3. То make a good grounding and prevent motor boating noise problem
connect another 12 gauge minimum wire from the (-) negative battery
terminal to chassis of stereo unit.
4. Connect the ‘Remote’ pole to external switch for positive 12V ON/OFF. This
may be connected to the receiver power antenna lead.

. POWER ON LED
Lights up when the remote on system is energized.
. PROTECTION LED
The protection circuitry will disable the amplifier if it senses an input overload,
speaker short circuit or extreme high temperature conditions. When the protec-
tion circuit is in operation the LED indicator on the unit will light indicating that
the amplifier has gone into a self preservation mode. At this time please check
your system to see what is causing the protection circuit to fire. The amplifier
can be reset by turning the remote power off and then on again. If the system
shuts down because of a thermal overload condition, allow the amplifier to cool
down before restarting. If the amplifier shutdown because of an input overload
or speaker short circuit please be sure to correct these conditions before restar-
ting the amplifier.
. LOW LEVEL INPUT (HIGH IMPEDANCE)
This unit is provided with gold plated RCA input Jacks for High impedance in-
put. Couple the RCA input with the car stereo output using RCA type connector
cables.
. GAIN CONTROL
Adjusting the control will match the output of the stereo to the amplifier. Turn
the control clockwise for more volume and counter-clockwise for less volume.
If there is distortion when the volume of stereo is turned up, turn the control down.
. CROSSOVER FREQUENCY CIRCUIT
Lets you adjust the crossover frequency from 45-400 Hz for both channels.
. CROSSOVER FREQUENCY ON/OFF SWITCH
Let you set the amplifier to drive a connected subwoofer.
. HIGH LEVEL INPUT (LOW IMPEDANCE)
If your car stereo does not have RCA output jacks, you can connect the speaker
output from the stereo system to the amplifier.

tions. Be sure to strip just enough insulation off your speaker wires that will
fit under the screw plate to help ensure against speaker wire short circuits.
TRI-MODE BRIDGING CAPABILITY. (PB-601)
The Amplifier can be bridged into the following systems.
A. Three channel Mode. Bridge Channels 3 & 4 into one high power channel
for subwoofer application while leaving channels 1 & 2 in the stereo mode-
for satellite components.
B. Two Channel Mode. Bridge channels 1 & 2 into one high powered channel.
Bridge channels 3 & 4 into a second high powered channel. Be sure to utilize
speakers which can handle at least 100 Watts RMS on the bridged channels.
MUTE TURN ON CIRCUIT
The Amplifier features an anti-thump delay circuit. This circuit eliminates irritating
thump noises some times experienced with cheaper amplifiers when they are
turned on.
