AMPLIFIER SETTINGS Signal Input and Output Configurations The input section of the amplifier consists of a phase switch that sets the output configuration, gain controls, and RCA inputs. The input section makes it easy to adapt this amplifier to most system configurations. Four-Channel Amplifier Input Configuration The 4CH / 2CH switch routes input from the front inputs to the rear section of the amplifier.
Fine Tuning the Crossover Frequency The crossover section is marked at four frequency points for ease of system adjustment. These points are 20Hz, 250Hz, 1kHz, and 3kHz. Specific crossover points can be chosen based on the recommended operational bandwidth of your speakers. Auxiliary Output Configurations The auxiliary outputs on Orion amplifiers offer easy, unlimited system expansion.
Speaker Connections Four Channel Stereo Configuration ● Front and rear channel lowest recommended impedance is 2W stereo ● Crossover mode, output, and gain configurations are independently adjustable between the front and rear channels. ● Two-channel or four-channel input can be used for this configuration. For source unit fading, use the four-channel input mode. ● Front and rear outputs can be configured for high-pass, low-pass, or full range operation.
Three Channel Stereo/Bridged Configuration ● Front channels are configured for two-channel stereo operation. ● Front channel lowest recommended impedance is 2W stereo. ● Rear channels are configured for a single channel bridged output. ● Rear channel lowest recommended impedance is 4W. ● Crossover mode, output and gain configurations are independently adjustable between the front and rear channels. ● Two-channel or four-channel input can be used for this configuration.
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.
amplifier is twisted or bent. Step 6 Turn the vehicle's key switch to the off position. 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 performance of your Orion amplifier.
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. Step 2 Turn the level controls of the amplifier to their minimum 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.
