Thank you for your purchase of Orion's 300D, 600D, 1200D, or 2500D power amplifier. Each Orion amplifier is designed to be the leader in its class offering the most power, advanced features, and extreme ease of use. In high-end sound systems or high SPL systems, Orion amplifiers 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 (600D, 1200D, 2600D only). RCA Inputs - accepts RCA input from a source unit, preamplifier, or equalizer.

RCAs to the RCA Inputs and the RCA outputs to the next Orion amplifier in the signal chain. When the switch is in the COPY position, the RCA output is an identical copy of the input signal. The signal passes through a buffer stage so that several amplifiers can be daisy chained without signal loss or overloading of the source unit.
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.
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.
WARNING! The Orion 2500D has two separate four-gauge power and ground inputs. Both pairs of connections must use 4 AWG power wire for proper operation. Failure to do this may damage the amplifier and is not covered under war- ranty.
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.
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.
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. Remember, beach blankets, last week's laundry, school books and homework papers located on top of the amplifier do not improve air flow and may become damaged.
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. Refer to the Signal Input and Output Level Controls and Speaker Connections sections of this guide for correct wiring instructions.
