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. 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.FULLILPF/HPF CROSSOVER SWITCH

For use with normal full range systems, this selector should be set to the

FULL position. If this AMPLIFIER is being utilized to power a CROSSOVER system, this selector should be set to either the HPF(HI PASS FILTER) or

LPF(LOW PASS FILTER) position to enable the built-in electronic crossover.

S.BASS BOOST CONTROL

The Bass-Boost dial increases the bass signal to the speaker.

6.LOW PASS CONTROL

The LPF

40Hz/350Hz lets you adjust the crossover frequency from 40Hz to 350Hz, this control is useful only for subwoofers and not you main speakers.

7.HIGH PASS CONTROL

The HPF 80 Hzl2.5KHz lets you adjust the crossover frequency from 80 Hz to 2.5KHz. lets you set the tweeter speakers.

8.POWER ON LED

Lights up when the remote on system is energized.

9.PROTECTION LED

The protection ci r c u itry will disable the amplifier if it senses an input overload, speaker short circuit of extreme high temperature conditions. When the pr o te c ­ tion circuit is the amplifier in operation the has

LED indicator on the unit will light indicating that 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 sy s te m shuts down because of a thermal overload condition, allow the amplifier to cool down before restarting If the amplifier shutdown restarting the amplifier. because of an i n pu t overload or speaker short circuit please be sure to correct these conditions before

13.TRI-MODE BRIDGING C APABILTY.

The Amplifier can be bridged into the following systems.

A three channel Mo d e. B rid ge subwoofer application while lea lite

Channels 3 & 4 into one high power channel for v i n g channels 1 & 2 in the stereo mode for satel­ components.

B. T w o Channel Mode. Bridge channels 1 & 2 into one high powered channel.

Bridge channels 3 & 4 i nt o a second high powered channel. Be sure to utilize s peak e r which can handle at rated power on the bridged channels.

14.MUTE TURN ON CIRCUIT

The Amplifier features ing thump noise turned on. an anti-thump delay circuit. This circuit eliminates irritat­ some times e x peri e n ced with cheaper am p lifi e r s when they are

NOTE: Do not use both low and high level inputs simultaneously!

RCA TYPE TERMINAL

This am pl ifier is provided with g o ld p l a t ed RCA terminals for LOW LE VEL

INPUT to match radios and e q u a li z e r s with line level output.(Fig. 1A)

If you STEREO has only RIGHT and LEFT o u tpu t s 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.

1. If your STEREO on ly use RI GHT and LE F T outputs. please w i re as (Fig. 2A)

2. If your STEREO has four channel outputs please wire as (Fig. 2B).

NOTE: Do not use both low and high level i n puts simultaneouslyl

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.

Choose a suitable location to 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.

TESTING AND SPECIFICATIONS

J

1. After all the connections have been made, turn on your stereo and l i sten for the amplif ie r to turn on. If there are any un u 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 j u st 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 aver ag e listening level.

(e) Turn the radio volume all the way down <lnd listen for background noise.

(D) Start your vehicle and listen for electrical noise.

(E) Making fine adjustments to the s ens i t i v i ty can reduce background no i se and

Some engine noise.

(F) CAUTION: Never turn th e s ens i tiv i ty up any farthe r than you need to get clear sound at 2/3 volume.

(G) This adj u st m e n t only n eeds to be made once.
