User manual DEI ORION 4002

[. . . ] . 16 ©2003 Directed Electronics, Inc. 1 INTRODUCTION Thank you for your purchase of Orion's 4002 or 6002 amplifier. Each Orion amplifier is designed to be the leader in its class offering the most power, advanced features, and ease of use. Orion amplifiers are designed as the best affordable high end car audio amplifier money can buy. Listed below are the features of the new Orion 4002 and 6002. 4002 - 100 Watts per channel, two-channel amplifier with dual built-in fully variable high-pass, low-pass, and band-pass 12dB/octave crossovers and INTELLi Bass. [. . . ] For optimal results, mount the amplifier with as much clearance as possible. This type of mounting will yield the best cooling due to the convection effect of the amplifier chassis. General Precautions and Installation Tips WARNING!Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines, vacuum lines, or electrical wiring when working on your vehicle. Disconnect the vehicle's ground wire at the battery before making or breaking connections to the audio system's power supply terminals. Failing to securely mount the amplifier can result in damage or injury, particularly in the event of an accident. An unmounted amplifier becomes a dangerous projectile in the event of a crash. Route the wires where they will not be scraped, pinched or damaged in any fashion. The +12V power supply wire must be fused as close as possible to the battery terminal, ideally within 18". Use the recommended fuse size or circuit breaker listed in the Power Connections section of this manual. If you need to replace the fuse plugged into the side of the amplifier, replace the fuse with the same size ATC / MAXI type fuse that came with the amplifier. If you are not sure as to the correct value, refer to the Power Connections section of this manual for details. Using a higher current fuse may result in damage to the amplifier that is not covered under warranty. NOTE: Make sure all the equipment in the system is turned off when making or breaking connections to the input RCA's or speaker terminals. Turn on the system and slowly turn up the volume control only after double checking all wire connections. ©2003 Directed Electronics, Inc. 10 Power for systems with a single amplifier can be supplied by most automotive electrical systems. Systems with multiple amplifiers may require a higher capacity battery, alternator or the use of a storage capacitor. We strongly recommend the use of a Directed Audio Essentials power capacitor with an extra battery in larger stereo systems. Orion amplifiers generate a certain amount of heat as part of normal operation. Be sure the area around the amplifier is unobstructed to allow adequate air circulation. Remember, beach blankets, last week's laundry, school books and homework papers located on top of the amplifier do not improve air flow and may become damaged. Tools of the Trade Listed below are the majority of the tools required to perform an installation. Some of these tools are necessities; some will just make the job easier. Allen Wrenches (2. 5mm and 3mm) DMM or VOM Electric drill with assorted drill bits Grommets Heat shrink tubing Marking pen Nylon tie straps Phillips and flat blade screw drivers Pliers (standard and needle nose) Reference CD with 1 kHz Sine Wave at 0dB level (all bits high) RTA (real time analyzer) Soldering iron and solder Utility knife Wire brush or sandpaper for chassis grounding Wire crimper Wire cutters Wire strippers Step By Step Installation Step 1 Step 2 Step 3 Determine the location for the amplifier. Refer to the Choosing Mounting Locations section of this guide for detailed information. For system suggestions, refer to the Speaker Connections section of this guide. Run all the wires from the amplifier location to the speakers, source unit, and battery. [. . . ] Refer to the Adjusting the Sound of the System section of this manual for detailed instructions. Check speaker impedance load, if below 1W, rewire the speakers to achieve higher impedance. Refer to the Speaker Connections section of this guide for detailed instructions. 14 ©2003 Directed Electronics, Inc.
