User manual DEI ORION 2500D

[. . . ] . 20 ©2004 Directed Electronics, Inc. 1 INTRODUCTION 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. 300D - 300 Watt single-channel Class D amplifier with built-in fully variable highpass, low-pass, or band-pass crossover with INTELLi Q. Equipped with optional remote gain, the 300D is capable of one-channel operation with a maximum power of 300 Watts into 1W. [. . . ] The addition of a ground wire from the battery to the chassis of the vehicle improves the ability of the battery to supply power to the amplifier. This is recommended because the current delivery of the factory electrical system was designed only to accommodate electronics supplied by the auto manufacturer. 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 warranty. The 2500D cannot be operated in a bridge or strapped configuration, attempting to do so will damage the amplifier. ©2004 Directed Electronics, Inc. NOTE: WARNING! 12 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. This will route the signal through RCA to the other (slave) amplifier. To set the PHASE switch on the (slave) amp, move the phase switch from 0 to 180, exactly opposite of the master amp. For the speaker connections, connect the positive (+) speaker lead from the speaker to the positive (+) speaker terminal of the master amplifier. On the negative (-) speaker connection, take the negative (-) speaker terminal of the master amplifier and connect it directly to the negative (-) speaker terminal of the (slave) amplifier. The remaining positive (+) speaker terminal of the (slave) amplifier must be connected to the negative (-) speaker lead from the speaker. For best results, connect both negative speaker terminals on the master amp to both negative terminals on the slave amp using at least 12 AWG cable. The Orion 2500D is not designed to work in a bridged or strapped configuration. Attempting to apply these configurations will damage the amplifier and will not be covered under warranty. WARNING! ©2004 Directed Electronics, Inc. 13 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. NOTE: Mounting amplifiers upside down is not recommended and may cause premature thermal shutdown. Amplifiers are not designed to endure the harsh environment of the exterior elements. WARNING! Passenger Compartment If you are going to mount the amplifier in the passenger compartment, make sure you have adequate room for ventilation. The amplifiers have been designed to make under-seat mounting possible. When mounting your amplifier under a seat or similar area, keep a minimum of 1" of clearance around the amplifier for adequate cooling. Trunk Compartment Mounting your amplifier in the trunk provides excellent performance as long as you do not restrict the airflow around the heatsink of the amplifier. For optimal results, mount the amplifier with as much clearance as possible. [. . . ] Refer to the Adjusting the Sound of the System section of this manual for detailed instructions. Check speaker impedance load, if below 1W, rewire the speakers to achieve higher impedance. Refer to the Speaker Connections section of this guide for detailed instructions. 18 ©2004 Directed Electronics, Inc. Symptom Distorted output 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. [. . . ]
