Page 3: Introduction
INTRODUCTION Thank you for your purchase of Orion's HP-2800, or HP-4800 power amplifier. Each Orion amplifier is designed to be the leader in its class offering the most power, advanced fea- tures, and extreme ease of use. In high-end sound systems or high SPL systems, Orion ampli- fiers will give you years of trouble-free performance. -
Page 4: Practice Safe Sound
PRACTICE SAFE SOUND™ Continuous exposure to sound pressure levels over 100dB may cause permanent hearing loss. High power automotive sound systems can generate sound pressure levels in excess of 130dB. When playing your system at high levels, please use hearing protection and avoid long term exposure. -

Low attenuates high frequencies and is used for subwoofer speakers. Intelli-Q Intelli-Q is incorporated in the HP-2800, and only on the rear channels of the HP-4800. Additionally, boost can be added by means of the Intelli-Q adjustment at the high-pass crossover frequency for improved bass output while still protecting the woofer from exces- sive excursion. -
Page 11: Adjusting Intelli-Q
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 sub- woofer. 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. -
Page 12: Infinite Baffle Example High-Pass Set At 30Hz
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. -
Page 13: 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 20: 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 21: 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 22: Set Up And Troubleshooting
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 per- formance of your Orion amplifier. -
Page 23: Adjusting The Sound Of The System
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. -

APPENDIX—PROGRAMMABLE FEATURES The following listing are ESP 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 fea- tures menu. NOTE: A setting marked “Reserved”... - Page 27 NOTE: Use caution when adjusting or unlocking gain as restricting the range or unlock- ing 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.
- Page 28 Event 1 through 7 - Stores up to seven recent events that have occurred to aid in diagnos- tic 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 writ- ten to the amplifier by the installer.
