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. Input Gain The Orion 300D, 600D, 1200D, and 2500D amplifiers have level adjustments to allow for easy integration with any source unit. The input sensitivity can be adjusted from 200mV to 5V.
When using Orion loudspeakers, minor deviations from the recommended frequency ranges can provide superior results depending on your speaker locations and your vehicle acoustics. Setting crossover frequencies higher than recommended will not cause damage and may provide superior sonic results depending on your system's performance goals. Refer to your loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for your system.

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 Gain Operation The remote gain port provides easy remote access to the internal gain structure of the HCCA power amplifier. The RGC-1 plugs into the amplifier via the 1/8" mini jack plug. The RGC-1 can be installed in the front of the vehicle to control the amplifier gain level. The RGC-1 can be used as a bass level control when used on an amplifier dedicated to subwoofers. In addition, one RGC-1 can be used on multiple sub amplifiers.
Speaker Connections The Orion 300D, 600D, 1200D, and 2500D amplifiers offer two positive and two negative output terminals for ease of connecting the speakers to the amplifier. Since these are mono amplifiers, the speaker connectors are paralleled internally. Each amplifier is stable to 1W. Bridging For bridging into a single speaker load, the Orion 600D and 1200D have the ability to be bridged with another amplifier of the same model. To do this you must utilize the COPY/GAIN/MASTER switch settings.
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 REM). 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.
