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 .
WARRANTY Directed Electronics, Inc. promises to the original purchaser , to replace this product should it prove to be defective in workmanship or material under normal use, for a period of two years .
SPECIFICA TIONS 1. All channels driven, continuous 4 W load 20Hz to 20kHz, < 0.05% THD, with input voltage at 13.8VDC. 2. All channels driven, continuous 2 W load 20Hz to 20kHz, < 0.
END P ANEL LA YOUT 1. Power LED - when lit indicates that the amplifier is on. 2. Front Low-Pass Cr ossover Switch - activates 2nd order low-pass crossover . 3. Front Low-Pass Fr equency Control - adjusts the frequency of the low-pass crossover . 4. Front Gain Contr ol - continuously adjusts from 200mV to 5V for full power output.
AMPLIFIER SETTINGS Signal Input and Output Configurations The input section of the amplifier consists of a phase switch that sets the output configura- tion, gain controls, and RCA inputs. The input section makes it easy to adapt this amplifier to most system configurations.
Fine T uning the Crossover Fr equency The crossover section is marked at four frequency points for ease of system adjustment. These points are 20Hz, 250Hz, 1kHz, and 3kHz. Specific crossover points can be chosen based on the recommended operational bandwidth of your speakers.
Speaker Connections Four Channel Stereo Configuration ● Front and rear channel lowest recommended impedance is 2 W stereo ● Crossover mode, output, and gain configurations are independently adjustable between the front and rear channels. ● T wo-channel or four-channel input can be used for this configuration.
Three Channel Stereo/Bridged Configuration ● Front channels are configured for two-channel stereo operation. ● Front channel lowest recommended impedance is 2 W stereo. ● Rear channels are configured for a single channel bridged output. ● Rear channel lowest recommended impedance is 4 W.
AMPLIFIER INST ALLA TION Choosing Mounting Locations The location of your amplifier will depend on several important issues. Due to the low pro- file size of the Orion amplifiers, there are many possible installation locations that will yield satisfactory amplifier performance.
Power for systems with a single amplifier can be supplied by most automotive electrical sys- tems. 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.
amplifier is twisted or bent. Step 6 T urn the vehicle's key switch to the off position. Step 7 Disconnect the vehicle's battery ground terminal. Step 8 Connect power wires to the amplifier (ground first, then 12 V(+) and RGC). Step 9 Connect the RCA and speaker wires to the amplifier .
Adjusting the Sound of the System Once you have checked the system's operation, adjust the sound of the system. Adjusting the sound of the system is accomplished by setting the level controls and adjusting the internal crossovers. Step 1 T urn the signal source volume control all the way down.
T roubleshooting Tips Symptom Probable Cause Action T o T ake No output Low or no remote turn-on Check remote turn-on voltage at voltage amplifier and repair as needed. Fuse blown Check power wire's integrity and check for speaker shorts. Fix as needed and replace fuse.
Symptom Probable Cause Action T o T ake Distorted output Internal crossover not set Readjust crossovers. Refer to the properly for speakers Internal Crossover Configuration section of this guide for detailed instructions. Speakers are blown Check system with known work ing speakers and fix or replace as needed.
