User manual PRECISION POWER DCX 500.2

[. . . ] While PrecisionPowerTM systems are capable of "Concert Level" volumes with incredible accuracy, they are also designed for you to enjoy at more reasonable levels all of the sonic subtleties created by musicians. Independent Line Output Crossover 30-4kHz PWM Power Supply Triple Darlington Output Stage. AP-IV Protection Circuity QBASSTM Bass Boost High Voltage Input Capability with -12dB Attention Switch. 2 Yr Warranty; if installed by an Authorized PrecisionPower Dealer. QBASS PLUS SPECIFICATIONS QBASS PLUSTM Up to 18dB of boost with selectable center frequency at 30Hz, 36Hz, 44Hz or 60Hz, with a Q-factor of 2. Optional QBASS REMOTETM This boost control can be mounted in the dash and will supersede the boost control on the amplifier endplate. 3 SPECIFICATIONS Power Ratings MODEL DCX 300. 2 DCX 500. 2 4 ohm 2 X 75 2 X 125 2 ohm 2 X 150 2 X 250 4 ohm MONO 1 X 300 1 X 500 All power ratings given above are tested at 12. 5V; 4 ohms; 20Hz - 200Hz. [. . . ] 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. With a small flat blade screwdriver, loosen the screws before attempting to insert the cable wires. 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. 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). This type of input works with any conventional RCA cables. 15 QBASS PLUS/QBASS REMOTE On DCX 300. 2, and DCX 500. 2 amplifiers, we've taken bass control to a higher level with QBASS PLUSTM. The two QBASSTM 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. On the rear end plate you will find the QBASSTM level control and plug-in for an optional QBASS REMOTETM dash mounted level control. Adjust the level control clockwise for up to +18dB of boost at your selected frequency. QBASSTM Settings 1 2 Freq. IN IN 30Hz IN OUT 36Hz OUT IN 44Hz OUT OUT 60Hz CAUTION: QBASS PLUSTM should only be used in systems with a strong subwoofer section. +18dB is a tremendous amount of bass boost and may damage your speakers or create excessive distortion if abused. The optional QBASS REMOTETM: This boost control can be mounted in the dash and will supersede the boost control on the endplate. The PrecisionPower DCXTM amplifiers no longer need an optional QPORTTM to connect multiple QBASS PLUSTM equipped amplifiers while using one QBASS REMOTETM. The new QBASS PLUSTM circuitry in the DCX amplifiers is now positioned before the crossover circuit. In doing this, PrecisionPowerTM engineers have allowed you to daisy chain your RCA output to the next amplifier input, causing the first amplifier's QBASS REMOTETM to become the master control amplifier. See your authorized PrecisionPowerTM dealer for more information! 16 TC-X CROSSOVER Your new DCX amplifier has a TC-X Crossover (Total Control Xover®) 30Hz-4kHz (see this guide for Crossover Chart). 12dB per octave phase correlated crossover built-in to provide superior system flexibility without the added expense and installation of an outboard crossover. The speaker outputs of your amplifier are high pass, low pass, or all-pass according to the HP/LP/FULL switch on the front endplate.
