- Page 6 All two-channel PCX™ amplifiers are capable of being bridged into a 4 ohm mono Both excessive temperature and low impedance (or short circuit) conditions will output without switches or bridging modules. This feature permits the creation of activate the amplifier's A M - V protection circuitry, which turns down the amplifier's a mono channel for a subwoofer or center channel.
- Page 7 Your multi channel PCX amplifier can use both front and rear outputs from your PCX 440 head unit to maintain the ability to fade front to rear, or you can run a single set of RCAs to the front inputs and push in the Rear Input INT/EXT switch on the amplifier endplate to route the front signal to the rear channels as well.
- Page 8 PCX 5800 Your New! PCX™ amplifier has a TC-X Crossover (Total Control X-over ) 30- © 4kHz (See page 17 for crossover Detent Chart). 12dB per octave phase correlat- ed crossover built in to provide superior system flexibility without the added expense and installation of an outboard crossover.
- Page 9 -12dB input attenuation switch. On PCX 480, PCX 4125 and PCX 5800 amplifiers, we've taken bass control to a higher level with QBASS PLUS™. The two QBASS™ switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers 30Hz, 36Hz, 44Hz and 60Hz.
- Page 10 PCX 480/4125 1. Cooling Plenums: Maintain a minimum 2” clearance around cooling plenums for proper amplifier cooling. 2. Front Freq. Control: Move this detented control in a clockwise rotation to adjust the front crossover frequency from 30Hz to 4kHz. 3. Front HP/LP/FULLSwitch: Select the desired crossover setting, HP/LP/FULLfor the speaker out- put signal of the front channel.
- Page 11 PCX 440 To manage the additional heat associated with higher output capability, a thermally controlled fan has been designed into the PCX 480 and PCX 4125. When the heatsink temperature reaches a pre-determined value, the fan is activated and cool air is drawn in through the lower intake vents on the endplate. This cool air flows below the circuit board, through the fan and across the internal f i n s , cooling the heatsink.
- Page 12 When using 16 gauge or larger, run the speaker wires from the amplifier location through the vehicle to the speakers. Observe the same precautions for routing these wires that you followed for running the power and remote turn-on wires. Cut o ff excess and, using wire strippers, strip 1/4 inch of insulation.
- Page 13 Locate an area near the amplifier(s) that is metal and clean an area about the size of a quarter to bare metal. Inspect the area around and underneath to be sure you won't drill into wires, brake or fuel lines, etc. Drill a pilot hole in the middle of this area.
- Page 14 Total Input Wattage = Current Draw (in Amps) Supply Voltage Example: A POWERCLASS™ PCX 4125 amplifier has two channels at 200w per channel RMS rating into 4 Ohms (125 x 4 = 500). You would use the formula in the following way: 500W x 2 = 1000W 1000W = 83.3 Amps Total current draw.
- Page 15 Up to 18dB of Boost with selectable center frequency at 30Hz, 36Hz, 44Hz or 60Hz, with a Q-Factor of 2. Optional QBASS REMOTE™ (PCX 480, PCX 4125, PCX 5800) This boost control can be mounted in the dash and will supersede the boost con - trol on the amplifier endplate.
