supply a remote turn on signal. DO NOT connect this terminal to constant (+) 12 volt. 4. GND - power return connection. Connect this terminal directly to the sheet metal chassis of the vehicle, using the shortest wire necessary to make this connection. Always use wire of the same gauge or larger than the (+) 12 volt power wire. The chassis connection point should be scraped free of paint and dirt. Use only quality crimped and/or soldered connectors at both ends of this wire.

AMPLIFIER SETTINGS Signal Input and Output Configurations Depending on your model, the input section of the amplifier consists of gain controls, high pass and low pass crossovers controls, Intelli-Bass control and RCA inputs and outputs. The input section makes it easy to adapt this amplifier to most system configurations. Input Gain These Orion amplifiers have level adjustments to allow for easy integration with any source unit. The input sensitivity can be adjusted from 150mV to 5V.
High-Pass Crossover When the switch is to the left (FULL position), the high-pass crossover is bypassed. When the switch is in the middle (HIGH position), the high-pass crossover is active. The high-pass crossover is continuously variable from 50Hz to 500Hz. Input Gain The Orion amplifiers have gain adjustments with an input sensitivity range from 200mV up to 5V on the RCA inputs and 1V to 10 on the high-level inputs.
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. The first example is an infinite baffle situation. The left graph displays the frequency response of a 12-inch woofer in an infinite baffle application without the high-pass filter, with the filter and with the filter and the INTELLi Q set to +3dB.
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. Vented Example High-Pass Set at 30Hz Vented enclosures benefit most from the Intelli-Q. Up to 10 dB of boost is capable at the box tuning frequency of 30 Hz. With +10dB of boost, the woofer has more output down to 22 Hz.
AMPLIFIER WIRING NOTE: Power and speaker connections to the amplifier should be made prior to final positioning and mounting of the amplifier in the vehicle. Power Connections ● Orion HP-2300 Fuse Size: 1 x 20 AMP ATC. ● Orion HP-2400 Fuse Size: 1 x 30 AMP ATC. ● Orion HP-2600 Fuse Size: 2 x 20 AMP ATC. ● Orion HP-4600 Fuse Size: 2 x 20 AMP ATC. ● Power connections accept up to 4 AWG wire. ● 4 AWG power and ground wire recommended for optimal performance.
Speaker Connections HP-2300, HP-2400, and HP-2600 One Channel/Two Channel Configuration The Orion HP-2300/2400/2600 amplifiers offer two positive and two negative output terminals for ease of connecting channel 1 and/or 2 outputs to the speakers. The amplifier is stable to 2W. See diagrams below. ● Lowest recommended impedance is 2W stereo. ● Outputs can be configured for high-pass, low-pass, or full range operation.
Three Channel (Channel 1, Channel 2, Bridged) ● Channels 1 and 2 are configured for two-channel stereo operation. ● Front channel lowest recommended impedance is 2W stereo. ● The third output is configured for a single channel bridged output. ● The bridged outputs lowest recommended impedance is 4W. ● Outputs are configured for high-pass, low-pass, or full range operation.
Speaker Connections HP-4600 The Orion HP-4600 amplifier offer four positive and four negative output terminals for ease of connecting channel 1, 2, 3, and 4 outputs to the speakers. The amplifier is stable to 2W. See diagrams below. Four Channel Stereo Configuration ● Channel 1/2 and channel 3/4 lowest recommended impedance is 2W stereo. ● Crossover mode, output, and gain configurations are independently adjustable between the front and rear channels.
Three Channel Stereo/Bridged Configuration ● Channels 1/2 are configured for 2-channel stereo operation. ● Channel 1/2 lowest recommended impedance is 2W stereo. ● Channels 3/4 are configured for a single channel bridged output. ● Channel 3/4 lowest recommended impedance is 4W. ● Crossover mode, output, and gain configurations are independently adjustable between channels 1/2 and 3/4. ● Two-channel or four-channel input can be used for this configuration.
Tri-Mode Six Channel Configuration ● Lowest recommended impedance is 2W stereo and 4W bridged mono. ● Front and rear outputs must be set for full range operation. ● Passive crossovers must be used on all components and frequencies must not overlap. WARNING! Failure to observe these requirements may result in damage to the amplifier.
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 8 Connect power wires to the amplifier (ground first, then 12 V(+) and REM). Do not connect the battery at this time. 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.
Step 7 If the output is clear and undistorted, continue to the Adjusting the Sound of the System section of this manual. 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.
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.
