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-Q control, 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.
WARNING! Exercise caution when setting INTELLi-Q. Maximum boost can potentially cause woofer damage due to over-excursion. Adjusting Intelli-Q Incorporated in the high-pass crossover, Intelli-Q maximizes the performance of a subwoofer. The high-pass subsonic filter removes unwanted bass output from the woofer, increasing the output of a subwoofer by as much as 3 dB due to the increased mechanical power handling.
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 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.
Remote Bass Operation (optional) The remote bass port provides easy remote access to the internal gain structure of the HP power amplifier. The optional HP-RB1 plugs into the amplifier via the 1/8" mini jack plug. The HP-RB1 can be installed in the front of the vehicle near the driver’s position to control the amplifier bass level. 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.

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. 22 Step 1 Turn the signal source volume control all the way down. Set any tone controls to their flat or defeated 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.
APPENDIX—PROGRAMMABLE FEATURES The following listing are ESP®-2 features that can be programmed or accessed by your installer to customize or troubleshoot your system. Factory default settings are shown in bold. NOTE: The Bitwriter® must have software version 2.3 or above to access the amplifier features menu. NOTE: A setting marked “Reserved” is for future development. Turn On Delay - 1.5, 2, 2.5, 3, 3.5, 4 seconds (approximate time delays).
NOTE: Use caution when adjusting or unlocking gain as restricting the range or unlocking the range can result in sudden increases in gain. The Valet Monitoring and Anti Theft options (below) require the ESP2 alarm to be “learned” into the amplifier. Prior to setting the valet or anti theft to Enable or On, execute the TXID routine. The ESP2 alarm must be the one installed in the vehicle. Valet Monitoring - Disable, Enable.
Event 1 through 7 - Stores up to seven recent events that have occurred to aid in diagnostic troubleshooting. The events that are retained are: Undervoltage, Overvoltage, Reserved, No Fault, Thermal, Overcurrent. These events are read-only, they and should not be be written to the amplifier by the installer. Event 1 is the most recent event, then Event 2, and so on. If event memory is full (Event 7 has a stored diagnostic message), then if another event occurs the 7th event will be pushed out of memory.
