Refer to the Internal Crossover Configuration section of this manual for detailed instructions. If using an HP-RB1, adjust the level to the output of the woofer to match the sonic requirements of the system. Step 12 Enjoy your awesome Orion sound system. © 2005 Directed Electronics, all rights reserved Troubleshooting Tips Symptom Probable Cause Action To Take No output 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. 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. Speaker wires not connected Check speaker wires and repair or replace as needed. Speakers are blown Check system with known work ing speaker and repair or replace speakers as needed. Audio cycles on and off Thermal protection engages when amplifier heat sink temperature exceeds 90°C (190°F) Make sure there is proper venti lation for amplifier and improve ventilation as needed. Loose or poor audio input Check RCA connections and repair or replace as needed. Loose power connections Check power wire and ground connections and repair or replace as needed. Amplifier level sensitivity set too high exceeding maximum capability of amplifier Readjust gain. Refer to the Adjusting the Sound of the System section of this manual for detailed instructions. Impedance load to amplifier too low Check speaker impedance load, if below 1W, rewire the speakers to achieve higher impedance. Shorted speaker wires Check speaker wire connections and fix or replace as needed. Speaker not connected to amplifier properly Check speaker wiring and repair or replace as needed. Refer to the Speaker Connections section of this guide for detailed instructions. Distorted output © 2005 Directed Electronics, all rights reserved Symptom Probable Cause Action To Take Distorted output Internal crossover not set Readjust crossovers. Refer to the properly for speakers 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. 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. Refer to the Internal Crossover Configuration section of this guide for detailed instructions. Impedance load at amplifier Check speaker impedance load, is too low if below 1W, rewire speakers to achieve higher impedance. Short in power wire or incorrect wiring Check power and ground connections and replace or repair as needed. Fuse used is smaller than recommended Replace with proper fuse size. Actual current exceeds fuse rating Check speaker impedance load. If below 1W, rewire speakers to achieve higher impedance. Fuse used is smaller than recommended Replace with proper fuse size. Impedance load at amplifier too low Check speaker impedance load. If below 1W, rewire speakers to achieve higher impedance. Speaker is blown with shorted outputs Check system with known work ing speakers and fix or replace as needed. Actual current exceeds fuse rating Check speaker impedance load. If below 1W, rewire speakers to achieve higher impedance.

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 - 0.75, 1.25, 1.75, 2.25, 2.75, 3.25 seconds. Delays the amplifier turn-on when the head or source unit is turned on. This eliminates any annoying pops or noise during power up from the head or source unit from feeding through to the amplifier. Service Code Display -OFF, Flash Code on LED, Reserved, Clear Last Fault. When set to “Off” the service code display will not be displayed on top of the amplifier (see Top Light Options feature below) and the amplifier operates normally. When set to “Flash Code on LED”, the LED on top of the amplifier will be enabled to flash the diagnostic code (see table below). The “Clear Last Fault” setting is used by your installer to clear the last fault event detected by the amplifier. NOTE: When the Clear Last Fault setting is used, execute a “read” cycle from the Bitwriter® prior to attempting further writes. This resynchronizes the Bitwriter®.
