User manual DEI ORION 8004

[. . . ] . 18 ©2004 Directed Electronics, Inc. 1 INTRODUCTION Thank you for your purchase of Orion's 8004 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 8004. 8004 - 100 Watts per channel, four-channel amplifier with dual built-in fully variable high-pass, low-pass, and band-pass 12dB/octave crossovers with INTELLi Bass. [. . . ] Crossover mode, output and gain configurations are independently adjustable between the front and rear channels. ©2004 Directed Electronics, Inc. 9 Two-channel or four-channel input can be used for this configuration. Front and rear outputs can be configured for high-pass, low-pass or full-range operation. Rear outputs are configured for summed bridged operation for subwoofer applications. Only the rear speaker is controlled when using the RGC-1. Tri-Mode Six Channel Configuration Lowest recommended impedance is 2W stereo and 4W bridged mono. Passive crossovers must be used on all components and frequencies must not overlap. Failure to observe these requirements may result in damage to the amplifier. WARNING! 10 ©2004 Directed Electronics, Inc. AMPLIFIER INSTALLATION Choosing Mounting Locations The location of your amplifier will depend on several important issues. Due to the low profile size of the Orion amplifiers, there are many possible installation locations that will yield satisfactory amplifier performance. Always mount the amplifier in a place that protects the amplifier from the elements. NOTE: Mounting amplifiers upside down is not recommended and may cause premature thermal shutdown. Amplifiers are not designed to endure the harsh environment of the exterior elements. WARNING! Passenger Compartment If you are going to mount the amplifier in the passenger compartment, make sure you have adequate room for ventilation. The amplifiers have been designed to make under-seat mounting possible. When mounting your amplifier under a seat or similar area, keep a minimum of 1" of clearance around the amplifier for adequate cooling. Trunk Compartment Mounting your amplifier in the trunk provides excellent performance as long as you do not restrict the airflow around the heatsink of the amplifier. 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. [. . . ] 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. 16 ©2004 Directed Electronics, Inc. Symptom Distorted output Probable Cause Action To Take Internal crossover not set properly for speakers Readjust crossovers. Refer to the Internal Crossover Configuration section of this guide for detailed instructions. [. . . ]
