PRECAUTIONS

1. Althoughthisunitisdesignedwithbuilt-inself-protectioncircuits, theremaybeapossibilityofdamageifitisnotwired

correctly. Please follow the wiring instructions carefully for the type of system being used.

2. Thelastleadtobeconnectedisthe wire to the positive (++

+)terminalofthebattery. Connectthiswireonlyafterhaving

completed and checked all other connections to the amplifier.

3. By nature of its design, a power amplifier generates heat and requires good air circulation around it to dissipate that

heat. Do not install the amplifier in an enclosed area which does not permit adequate air circulation. Should the

temperature of the unit rise too high, the internal thermal sensors will shut off operation until it has cooled down

sufficiently.

4. If fuse replacement is necessary, use only fuses of the same ampere rating as originally supplied with the unit. The

use of fuses with incorrect ratings may cause serious damage to the amplifier. If fuses blow consistently, carefully

check all electrical connections to the unit.

5. Supply of adequate battery voltage is critical to the proper operation of the power amplifier. The leads to the battery

and chassis ground mustmust

must

be of a thick enough gauge to provide this voltage to the amplifier. We recommend #10#10

#10#10

#10

gauge wire or larger (smaller gauge #) for the battery and ground leads.

6. Make certain that the speaker(s) to be used with this amplifier is capable of handling the output power (wattage) of

Inadequate air circulation will cause the

temperature of the amplifier to rise and will

trigger the thermal protection mode.

WIRING INSTRUCTIONS

Wiringyouramplifierwilldependon the system and speakers youareusing.Theamplifieriscompatible only with a radio

having a low-level stereo output, thereby instituting a mixed stereo-mono application. The following pages illustrate the

inputandoutputwiringforthistypeofinstallation,andanyothersetupattheuser'soption. Pleaserefertotheappropriate

diagrams for the system configuration.

The power and speaker wire connections for this amplifier are made via screw tightened terminal blocks. Loosen the

screw for the connection to be made and fully insert the wire (strip 1/2" of insulation from the end) under the respective

screw on the side panel (crimp-on "U" terminals are provided to simplify wiring and we recommend their use). Tighten

the screw down to secure the wire.

1. Power Connection1. Power Connection

1. Power Connection

The battery terminal (+12V) must be connected directly to the positive terminal of the vehicle battery to provide an

adequatevoltagesourceandminimizenoise. Connectingthebatteryterminalleadtoanyotherpoint(suchasthefuse

block) willreduce the poweroutput and maycause noise anddistortion. Use only #10#10

#10#10

#10 gaugeorthicker(smallergauge

#) wire for this lead and connect it to the terminal of the battery after all other wiring is completed.

2. Ground Connection2. Ground Connection

2. Ground Connection

The ground terminal (GND) connection is also critical to the correct operation of the amplifier. Use a wire of the same

gaugeasthepower connection(#10#10

#10#10

#10orthicker)andconnectitbetween thegroundterminal(GND)oftheamplifierand

a metal part of the vehicle close to the mounting location. This wire should be as short as possible and any paint or

rust at the grounding point should be scraped away to provide a clean metal surface to which the end of the ground

wire can be screwed or bolted.

3. Remote Turn-On Connection3. Remote Turn-On Connection

3. Remote Turn-On Connection

The amplifier is turned on by applying +12 volts to the remote turn-on terminal (REM). The wire lead to this terminal

should be connected to the "Auto-Antenna" lead from the car stereo which will provide the +12 volts only when the car

stereo is turned on. If the car stereo does not provide an Auto-Antenna lead, the remote turn-on lead may be wired

WIRING INSTRUCTIONS

toan "Accessory" or "Radio"terminal in thecar's fuse block. Thiswill turn the amplifieron and offwith the ignition key,

regardless of whether the car stereo is on or off. The remote turn-on lead does not carry large currents, so #20#20

#20#20

#20 gauge

wire may be used for this application.

4. Speaker Connections4. Speaker Connections

4. Speaker Connections

Only 4 Ohm or 2 Ohm impedance speaker(s) can be used with the amplifier. Wire it to the speaker terminals as per

the appropriate wiring diagram. For most applications, #18#18

#18#18

#18 gauge wire should be used for the speaker leads but in no

case thinner than #20#20

#20#20

#20 gauge. For leads in excess of 10 feet, #16#16

#16#16

#16 gauge is recommended. When wiring the speaker,

pay careful attention to the polarity of the terminals on the speaker and make certain they correspond to the polarity

ofthecorrespondingterminalsontheamplifier. DONOTDONOT

5. Input Connections

Thisamplifierfeatureslow-levelinputandoutputcapability,plusremotesub-wooferlevelcontrol. The low-level output

capability can be used if an additional amplifier is installed. When low-level outputs are provided from the car stereo,

this amplifier can be included in the audio system as shown in the associated wiring diagram. The amplifier low-level

inputs provide the lowest distortion and best performance. Use good quality shielded audio cables with RCA plugs at

both ends to connect the stereo to the amplifier and keep the cable lengths to a minimum to avoid noise.

If the car stereo does not provide low-level outputs, the amplifier cannot be used, since high level speaker inputs are

not provided.

6. Remote Sub-Woofer Level Control Connection6. Remote Sub-Woofer Level Control Connection

6. Remote Sub-Woofer Level Control Connection

Remote sub-woofer level control is provided by a PAB-RC control unit, which can be connected to the amplifier using

a REMOTE CONTROL telephone cable (supplied) with RJ-11 connectors at each end. Refer to the amplifier wiring

diagram for details.

OPERATION

1Power Indicator

The POWER LED functions as both a power and a

warning indicator. When the amplifier is off, the indicator

is inactive and appears white. When power is applied to

the amplifier, the LED indicator illuminates green, provided

no malfunction is present, thus signifying the amplifier is

operating normally. When the LED illuminates red, the

built-in self-protection circuits have been activated and

haveshut downoperation ofthe amplifier. Theprotection

circuits may be triggered by the temperature of the unit

rising above a safe level or by an overload condition. If

activated by a rise in temperature, the unit will resume

operation after cooling off to a normal operating range. If

activated by an overload condition, the source of the

overload must be found and corrected to resume normal

operation of the amplifier. Most overload conditions are

Afterinitialset-up,theamplifiershouldnotrequireanyfurtheradjustmentunlessthereisachangeinthecarstereoorspeaker

caused by mis-wiring or operation into incorrect speaker

loads. Re-check all wiring and connections if this

situation occurs and correct as necessary.

2Level(V) Control

The amplifier is capable of operating from audio signal

sources supplying a wide range of input levels. The

Level (V) control shouldinitiallybesettothe mid-position.

system. If,however,thereisstilloutputfromtheamplifier

when the car stereo volume control is at its minimum

setting, or the output level increases too fast with a small

rotation of the volume control, adjust the Level control to

decrease the output from the system.
