INTRODUCTION Thank you for your purchase of Orion's 600D, 1200D, or 2500D 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.
LIMITED TWO-YEAR CONSUMER WARRANTY Directed Electronics, Inc. promises to the original purchaser, to replace this product should it prove to be defective in workmanship or material under normal use, for a period of two years from the date of purchase by the dealer as indicated by the date code marking of the product PROVIDED the product was installed by an authorized Directed dealer.

END PANEL LAYOUTS Power LED - when lit indicates that the amplifier is on. Gain Control - continuously adjusts from 200mV to 5V for full power output. Copy/Gain/Master Switch - determines the configuration of the RCA outputs. RCA Inputs - accepts RCA input from a source unit, preamplifier, or equalizer. RCA Outputs - provides easy connection to additional amplifiers.
13. Remote Gain Jack - connects optional RGC-1 (remote gain control). 14. 1 MAXI Fuse (600D) - protects the amplifier from over current situations. 3 ATC Fuses (1200D) - protects the amplifier from over current situations. 16. Power Connections - accepts up to 4 AWG power and ground cables.
Input Gain The Orion 600D, 1200D, and 2500D amplifiers have level adjustments to allow for easy inte- gration with any source unit. The input sensitivity can be adjusted from 200mV to 5V. Refer to Testing the System and Adjusting the Sound of the System sections of this guide for detailed instructions on setting the gain.
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.
Enclosure Type Infinite Baffle Tune above Fs of woofer Sealed Tune above Fs of woofer Vented Tune to port frequency Sealed Band-pass Tune above Fs of woofer Vented Band-pass Tune to port frequency Aperiodic Set crossover to Fs of woofer 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.
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.
RCA output selection switch in the MASTER position. The RGC-1 information will now be sent to subsequent amps via the MASTER signal. AMPLIFIER WIRING Power Connections for the 600D and 1200D Orion 600D Fuse Size: 1 x 50 AMP MAXI Orion1200D Fuse Size: 3 x 40 AMP ATC Power connections accept up to 4 AWG wire.
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 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.
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.
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.
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 con- trols to their flat or defeated positions.
