[. . . ] Keep in mind that your amplifiers simply convert electrical energy to acoustical energy, and any electrical deficiency will compromise the performance of your sound system. For more information about charging system upgrades, see you local authorized PrecisionPowerTM Dealer or call PrecisionPowerTM Technical Support at 1-800-62POWER x2033. CURRENT DRAW The following is a basic formula to be used as a guide to determine current draw. Your new DCX amplifier is more efficient than most other amplifiers. This formula is to be used as a guideline. Using wire of a larger gauge can only improve the current transfer of your system. Total RMS output X 1. 5 = Total Input Wattage Total Input Wattage = Current Draw (in Amps) Supply Voltage Example: A DCX amplifier has two channels at 125 watts per channel RMS rating into 4 ohms (125X2 = 250 watts). You would use the formula in the following way: 500 W X 1. 5 = 750 watts 750W = 62. 5 Amps total current draw 12V 10 If the same amplifier is driven into a 2 ohm stereo or 4 ohm mono load, double it's 4 ohm RMS rating. All DCX amplifiers will effectively double their power at this load. 500W X 1. 5 X2 = 1500 watts 1500W = 125 Amps total current draw 12V If you are using more than one amplifier, add up the total current draw for all of them and choose the appropriate gauge based on the grand total. POWER WIRE SIZE A minimum of 8 gauge or a maximum of 4 gauge wire is recommended dependent on the application. The ground wire must be the same gauge as the power wire. 11 POWERLOCK CONNECTORS Once you have run both the power and ground wires, then connect the cables to the amplifier. Cut off excess wire, and using wire strippers, strip the ends of the power and ground cables approximately 1/4 inch. Locate the PowerLockTM power and ground connector (supplied). With a small flat blade screwdriver, loosen the screws before attempting to insert the cable wires. Insert the wires into the appropriate hole, and tighten the screws. Once the wires are secure, the PowerLockTM may be plugged into the amplifier. The Power/Ground PowerLockTM will accommodate 4 gauge wire for the DCX 300. 2, and DCX 500. 2. 12 DCX 300. 2, DCX 500. 2 FRONT PLATE DIAGRAM 12 11 DC X 300. 2 2 Fr Panel ont R BR I G E D + O U TPU T XO VER FR EQ Q BASS ATT G AI N R XO VER LP LP L R - R + R EM L+ L30 40k 2 1 12dB MI N M AX O U TPU T FR EQ FU LL H P 30 40k L I TPU T FR EQ FU LL H P N 1 2 3 4 5 6 7 8 9 10 1. Cooling Plenums: Maintain a minimum 2" clearance around cooling plenums for proper amplifier cooling. Speaker/Remote Connector: Plug in the PowerLockTM connector here. This circuit completely isolates the chassis ground from the audio circuit of the amplifier and reduces noise radiated into your signal cables by up to 40dB. This is equivalent to a noise reduction of approximately one hundred times what the noise level would be without this circuitry. It provides all the benefits of a true balanced line without the need of any special cables (see diagram below). [. . . ] No obstruction should be within 2" of the amplifier on all sides. Note: Low battery voltage will cause the amplifier to run warmer and possibly damage the amplifier. 19 TROUBLESHOOTING NO SOUND Is the LED illuminated?YES NO Check Power and Remote turn-on wire for voltage.
