OWNER'S MANUAL PB618/PB718/PB918/PB2518/PB3818
INTRODUCT I ON (PB618) Thank you for purchasing the Pyr am id AMERICA H i gh Speed Power Amp lifier The AMPLIFIER has been designe d using the latest e lect ronic technology avail ab le The AMPLIFIER is with engineered features allo wing you to prod uce high qu ality stereo reproduction in mobile applications. This in n ovat ive system has been deS igned A 12 volts DC negative ground power supply. Easy installation with m o unt ing Hardware is provided. . .
FUNCTIONS (PB618) 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 amplifier. 2.LOW LEVEL INPUT (HIGH IMPEDANCE) This unit is provided with RCA input jacks for High impedance input. Couple the RCA input with the car stereo output using RCA type connector cables. 3.LEVEL CONTROL Adjusting the control will match the output of the stereo to the amplifier.
FUNCTIONS ( PB618) 9.PROTECTION LED The protection ci rc uitry will disable the amplifier if it senses an input overload, speaker short circuit of extreme high temperature conditions. When the pro tec 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.
ELECTRICAL & AUDIO CONNECTIONS (PB618) A. STEREO INPUT CONNECTION NOTE: Do not use both low and high level inputs simultaneously! RCA TYPE TERMINAL This am plifier is provided with g old p lated RCA terminals for LOW LEVEL INPUT to match radios and eq u alizers with line level output.(Fig. 1A) If you STEREO has only RIGHT and LEFT o utpu ts then you must use a Y-adaptor connecting the stereo to the amplifier as indicated. (Fig. 1 B) WHEN YOU WANT TO BRIDGE THE AMPLIFIER PLEASE COMPLET THE FOLLOWING STEPS.

PROTECTION LED The protection circuitry will disable the amplifier if it senses an input over load, speaker short circuit of extreme high temperature conditions. When the protection 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.

POW ER CONNEC TI ON D.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. To make a good grounding and prevent motor boating noise problem con· nect another 12 gauge minimum wire from the (-) negative battery terminal to chass is of stere o u n it . 4. Connect the 'Remote' pole to external switch for positive 12V ON/oFF.
INSTALLATION The Amplifier comes complete with all mounting hardware, While the Amplifier can be mounted in any convenient location in your vehicle, please remember that this is a 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. Allow enough space around the cooling fins to permit reasonable airflow and cooling.
TESTING AND SPECIFICATIONS J 1. After all the connections have been made, turn on your stereo and listen for the amplifier to turn on. If there are any unu sual noises from the speakers then turn the system off and recheck all wiring. 2. After you have connected your radio or requallzer to the amplifier, you may ad just the gain control to match the output level of your radio. (A) Set the volume control on you radio to 2/3 position (8) Adjust the gain control for an average listening level.
