(1984-MSRP $289.00)

OWNER'S MANUAL AND

INSTALLATION GUIDE

INTRODUCTION

Your new Linear Power™1002© amplifier employs a sophisticated design

combining reliability, high power, low distortion, and freedom from external noise.

When properly installed, it will give long and faithful service. When combined with

other high quality components, it will be the heart of a superb system. Thank you

for purchasing a Linear Power™ Product.

TECHNICAL DESCRIPTION

POWER SUPPLY: Self oscillating for reliability and efficiency. The transformer is

epoxy dipped for extreme vibration resistance.

OUTPUT STAGES: Transformer less, direct coupled and fully complimentary.

Output transistors are high current and low distortion TO-3 Devices in the 1002

©,

operating at a fraction of their limitations. Total power dissipation potential of the

output transistors is well over 500 watts.

PROTECTION: Our stable amplifier design is made virtually indestructible by two

separate forms of protection. First is an all-new Thermal Protection Circuit, which

is designed to prevent damage from high frequency oscillations or excessive

ambient temperature. The second form of protection protects the amplifier from

short circuits in the installation. Both circuits are automatically resetting.

CONSTRUCTION FEATURES: The infinitely variable input sensitivity control

permits optimal signal matching for lowest noise and lowest distortion with

virtually any source. All components used are rated for at least 150% of their

intended use, and are mounted on double-sided fiberglass epoxy circuit boards.

QUALITY CONTROL: In-house construction of critical components like transformers and chassis pieces, as well as total assembly, allows LINEAR POWER™ to maintain uniform quality. 100% of the finished units are tested, then burned in for four hours, and tested again. Amplifiers, which pass these rigorous controls, have truly earned the LINEAR POWER™ Logo. INSTRUCTIONS Read the following instructions completely through.

4. +12V FOR TURN-ON: The red and white wire is not a main power source for the amplifier, but acts as an electrical switch to turn the amplifier on and off. It should be connected to the power antenna lead from the radio. Where no power antenna lead exists, a source of 12 volts connected through a toggle switch will do. DO NOT CONNECT DIRECTLY TO A SOURCE THAT WILL LEAVE THE AMPLIFIER PERMANENTLY ON, AS THIS WILL DRAIN THE BATTERY. 5.

1002 Speaker Connector OPERATION IN BRIDGE MODE The Model 1002© amplifier must use an external pre-amp or crossover to be used as a bridgeable amplifier. They must be bridged using a Linear Power™ crossover such as the Linear Power™ XO-1©, XO-2©, or similar brand crossover or pre-amp with inverting capabilities. One channel of the inputs of these amplifiers must receive an inverted signal in order to have the needed inverted signal on one channel at the output.

The large Red Wire (2) The (Red/White) wire but not at the large Black. Check by substitution or other method for proper operation of music source. BLOWS FUSE: Check all connections to be sure all power wires and speaker wires do not touch ground or each other. Re-check polarity of main power wires. SHUTS OFF: As this amplifier is equipped with a thermal and a short circuit shutdown system in the unlikely event of excessive temperatures due to high ambient temperature, improper speaker impedance, etc.

NOISE TROUBLESHOOTING PROCEDURES 1. Start engine and let idle. 2. Turn system on. ADJUST INPUT GAIN ON AMP SO THAT IT IS TURNED DOWN AS FAR AS POSSIBLE TO STILL PRODUCE ADEQUATE LISTENING LEVELS. 3. Slowly increase and decrease engine speed. 4. Take note as to the type and amount of noise while slowly varying the volume control on the music source from minimum to average levels. 5. If noise is a popping or ticking sound, increasing in speed with engine speed, the source is probably the ignition system.

insulation exposing the ground braid. Cut the braid and fold back Strip 2-3 of insulation off a scrap piece of wire and wrap around the ground braid next to the plug closest to the amp and wrap the entire connection with electrical tape. Try grounding this signal ground at several different locations in the vehicle while carefully listening to the amount of engine noise at each location. Attach this signal ground wire to the location, which causes the least amount of engine noise.
