END PANEL LAYOUT 1. Power LED - when lit indicates that the amplifier is on. 2. Stereo/Mono Switch - configures the amplifier for one or two inputs. 3. Gain Control - continuously adjusts from 200mV to 5V for full power output. 4. Copy/Gain/Master Switch - determines the output of the RCA outputs. 5. RCA Inputs - accepts RCA input from a source unit, preamplifier, or equalizer. 6. RCA Outputs - provides easy connection to additional amplifiers. 7.
Stereo / Mono Input Configuration The STEREO / MONO switch allows the Orion 8002 amplifier to use a single RCA or highlevel input to feed signal to both the right and left channels of the amplifier. When the switch is to the right (MONO position), signal from the left input is routed to the right channel. When the switch is to the left (STEREO position), right and left inputs are independent. This allows a source unit with an internal balance to change the stereo imaging.
Internal Crossover Configurations The crossover section of the Orion 8002 amplifier is continuously variable and extremely flexible. There are different crossover configurations possible allowing high-pass, low-pass, and band-pass configurations. The high-pass crossover incorporates the INTELLi Q feature. This circuit is designed to optimize the performance of Orion subwoofers in all types of enclosures.

Sealed Example High-Pass Set at 20Hz This sealed example is the same 12-inch woofer in the recommended sealed enclosure. Up to 6 dB of boost is capable if 20 Hz was used. With +6dB of boost, the woofer has more output down to 15 Hz. Sealed Example High-Pass Set at 30Hz In this example, the frequency has been increased to 30 Hz. Up to 6 dB of boost is capable at this frequency. With +6dB of boost, the woofer has more output down to 23 Hz. The overall usable output is increased.
AMPLIFIER WIRING Power Connections ● 8002 Fuse Size: 1 x 80 AMP MAXI ● Power connections accept up to four-gauge wire. ● Four-gauge power and ground wire recommended for optimal performance. ● Connect 12V+ to the battery through fuse holder. This connection provides +12V main power to the amplifier. ● Power wire must be fused no more than 18" from battery. ● Ground amplifier to a good chassis ground as close as possible to the amplifier.
Summed Bridged Configuration ● Lowest recommended impedance is 4W bridged mono. ● Mono or stereo input can be used for this configuration. ● Outputs can be configured for high-pass, low-pass, or full range operation. ● Output is configured as summed bridged which is ideal for subwoofer applications. Single Channel Bridged Configuration ● Lowest recommended impedance is 4W mono. ● Mono input must be used for this configuration. Only the Left input is used.
Tri-Mode Three Channel Configuration ● Lowest recommended impedance is 2W stereo and 4W bridged mono. ● Stereo operation must be used. ● Outputs must be configured for full range operation. ● Output is configured stereo and summed bridged. ● Passive crossover frequencies must not overlap. WARNING! 12 Failure to do so may result in damage to the amplifier. ©2003 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. In addition, mount the amplifier on a stable, flat surface.
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.
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. Check the quality of your speakers and signal connections. This will determine the ultimate performance of your Orion amplifier. Refer to the Signal Input and Output Level Controls and Speaker Connections sections of this guide for correct wiring instructions.
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 Turn the signal source volume control all the way down. Set any tone controls to their flat or defeated positions. This includes the loudness control. Step 2 Turn the level controls of the amplifier to their minimum positions.
Troubleshooting Tips Symptom Probable Cause Action To Take 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. No output Power wires not connected Check power wire and ground connections and repair or replace as needed. Audio input not connected Check RCA connections and repair or replace as needed.
Symptom 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. Speakers are blown Check system with known work ing speakers and fix or replace as needed. Distorted output Poor bass response Speakers wired with wrong Check speaker polarity and fix polarity causing cancellation as needed. at low frequencies Crossover set incorrectly Reset crossovers.
