INTRODUCTION
The PB660. PB860. P1460 utilizes 8 MOSFETS 2 TRANSFORMER inits
design te produce enough voltage to supply the main amplifier and a huge
considerable amount of reserve voltage for peak "high demand" situations.

FUNCTIONS
1.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 ampliher.
2. LOW LEVEL INPUT (HIGH IMPEDANCE)
This unit is provided with gold plated RCA при! jacks for High Impedance
input. Couple the RCA input with the car stereo output using ROA type connec-
tar cables.
3.LEVEL CONTROL
Adjusting the control will match the output of the stereo to the amplifier. Turn 1
the control clockwise for more volume and counter-clockwise for less volume if
there 15 distortion when the votume of stereo is turned up, turn ihe control
dere.
4. FULL/LPF/HPF CROSSOVER SWITCH
For use with normal full range systems, this selector should be set to the
FULL position. this AMPLIFIER is being utilized to power а CROSSOVER
system, this selector should be set to either the HPF(AI PASS FILTER) or 1
LPFILOU PASS FILTER) position to enable the built-in electronic crossover.
5.BASS BOOST CONTROL
The Bass-Boost dial increases the bass signal to the speaker,
6. LOW PASS CONTROL
The LPF 40Hz/3450Hz lets you adjust thé crossover frequency fram 40Hz
to 350Hz, this control is useful only for subwooters and not you main speakers.
7. HIGH PASS CONTROL
The HPF S8Hz/f? SKHz lets you adjust the crossover frequency from SOHz
te 2 SKHz. lets you set the tweeter speakers.
3.POWER ON LED
Lights up when the remote on system is energized.
FUNCTIONS
9. PROTECTION LED
The protection circuitry will disable the amplifier if it senses an input overload,
speaker shart circuit of extreme high temperature conditions. When the protec-
tion circuit 18 in operation the LED indicater 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
restarting the amplifier.
10.POWER SUPPLY
À. +12
To connect +12 DC power supply wire from the terminal of battery.
BE, GROUND
То connect the ground wire from the chassis of the automobile.
©. REMOTE
To connect the control wire which provides remote turn on and off of the ampli-
fier Бу the radlo/cassette player. (Usually The Auto Antenna Lead)
11.POWER FUSE
The power fuse protects both this amplifier and the automobile electrical
system from short circuit conditions.
12 SPEAKER TERMINALS.
The speaker terminals are 14K Gold Platea for high conductivity and minimum
impedance loss. The terminals are facing upwards fer easy wiring in tight situa-
tons. Be sure fo strip just enough insulation off your speaker wires that will fit
under the screw plate to help ensure against speaker wire short circuits.
13.TRI-MODE BRIDGING CAPABILTY.(PB660.PB4660.PB1460)
The Amplifier can be bridged inte the following systems.
A. three channel Mode. @ridge Channels 4 & 4 into one high power channel for
subwooter application while leaving channels 1 & 2 in the stereo mode for satel-
ite components.
В. 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
speaker which can handle at rated power on the bridged channels.
14.MUTE TURN ON CIRCUIT
The Amplifier features an antithump delay circuit. This circuit eliminates irritat-
Ing thump noise some times experienced with cheaper amplifiers when they are
turned on.

The Amplifier comes complete witn all mounting hardware, While the Ampiifier can
be mounted in any convenient locatian in your vehicle, please remember that this
Is а high power unit which generates high electrical energy and heat. Therefore be
sure to install the unit in a place with sufficient airflow. a minimum of dust and no
moisture Alow enough space around the cooling fins to permil reasonable airflow
and coohng.
Choose a suitable location te mount the amplifier so that it is protected from vibration
Check clearance all around the amplifier be sure to leave enough room for wiring.
secure the amplifier tightly Do not leave an unmounted amplifier in your car trunk
or deck as It can be a driving hazard should you be forced to make a short stop.

‚ After all the connections have been made, turn en your =leseo and listen for the
amplifier to turn on. If there are any unusual noises from Ihe speakers then turn
the system off and recheck al! wiring.
. Alter you have connected your radio or requalizer to the amplifier, you may ad-
just the gain contrat to match the output level of your radio.
{A} Set the volume control on you radio to #73 position.
(8) Adjust the gain control for an average lstening level.
{С} Turn the radio volume all the way down and listen for background naiss.
(Di Start your мене and listen for electrical poise.
{E} Making fine adjustments to the sensitivity can raduce background noise and
