Precision Power DCX 800.5, DCX 300.4, DCX 1000.4 manual Mixed Mono Output

modules. This feature permits the creation of a mono channel for a suitable subwoofer or center channel. Deriving the mono channel is accomplished by using the Left Channel Positive wire (L+) as the positive speaker wire and the Right Channel Negative wire (R-)as the negative speaker wire.

Note: It is important that a minimum 4 ohm impedance is observed. If the impedance drops below 4 ohms while the amplifier is wired in the bridged configuration, the amplifier’s protection circuitry may engage.

Note: This does not apply to the DCX 800.5 sub channel, which can drive a 2 ohm load safely.

MIXED MONO OUTPUT

The ability to run stereo speakers while simultaneously running a mono output from the same amplifier is accomplished by running the stereo speakers normally and tapping into the appropriate wires for the “mixed mono” channel (left channel positive for the positive speaker wire and right channel negative for the negative speaker wire). Speaker impedance should be no lower than 2 ohms on the stereo channels and 4 ohms on the mono channel.

Note: Passive crossovers must be used for “mixed mono” operation. Choose a low pass crossover around 100Hz for your subwoofer, then choose a high pass crossover for your stereo channels. The high pass crossover must be at the same or slightly higher frequency than the low pass crossover to maintain the correct impedance. See your PrecisionPower dealer or call 1-800- 62POWER for more information about passive crossovers.
