Page 6: End Panel Layout
END PANEL LAYOUT Power LED - when lit indicates that the amplifier is on. Stereo/Mono Switch - configures the amplifier for one or two inputs. Gain Control - continuously adjusts from 200mV to 5V for full power output. Copy/Gain/Master Switch - determines the output of the RCA outputs. RCA Inputs - accepts RCA input from a source unit, preamplifier, or equalizer. -
Page 7: Stereo / Mono Input Configuration
Stereo / Mono Input Configuration The STEREO / MONO switch allows the Orion 8002 amplifier to use a single RCA or high- level 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 chan- nel. -
Page 8: Internal Crossover Configurations
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. -

Enclosure Type Infinite Baffle Tune above Fs of woofer Sealed Tune above Fs of woofer Vented Tune to port frequency Sealed Band-pass Tune above Fs of woofer Vented Band-pass Tune to port frequency Aperiodic Set crossover to Fs of woofer Infinite Baffle Example High-Pass Set at 30Hz By removing low frequency signal that the woofer cannot produce, the woofer can play its capable range louder. -
Page 10: Sealed Example High-Pass Set At 20Hz
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 out- put down to 15 Hz. -
Page 11: Amplifier Wiring
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. - Page 12 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.
- Page 13 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! Failure to do so may result in damage to the amplifier.

Page 14: Amplifier Installation
AMPLIFIER INSTALLATION 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. Always mount the amplifier in a place that protects the amplifier from the elements. -
Page 15: Tools Of The Trade
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. -
Page 16: Set Up And Troubleshooting
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 per- formance of your Orion amplifier. -
Page 17: Adjusting The Sound Of The System
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 con- trols to their flat or defeated positions. -
