DESCRIPTION
•The Clarion DPX1000.2 two-channel amplifier provides 250 watts x2 into a 4 ohm load, 450 watts x2 of power into a 2 ohm load. and 500 watts x2 into a 1 ohm load. This full featured model is an excellent choice for a variety of car audio sound system configurations.
•The DPX1000.2 is Clarion’s first amplifier using Digital Technology
The DPX1000.2 uses an unregulated MOSFET power supply for superior control of output wattage. A toroid-coil transformer yields maximum power transfer with minimum heat loss. Careful attention to circuit design keeps AM RFI at low levels, so you won’t hear unwanted noise when the level is cranked up. Protection circuits safeguard the amplifier when overheating and speaker shorts or improper load conditions occur.
• All connections and controls of the DPX1000.2 are on the end panels and are DESCRIPTION
easy to understand. We use gold-plated RCA and barrier connectors to ensure the best electrical connection for your system. Included is a wired remote sub level control (BC2) for adjusting the amplifier gain from the front of the vehicle.
• Multimode operation is a unique feature that allows the DPX1000.2 to maximize power output at different loads. In the regular mode (loads of 4 ohm or 2 ohm stereo), the power output is 250 watts x2 into 4 ohms and 450 watts x 2 into 2 ohms. With a 1 ohm load, the power output will increase to 500 watts x 2. This feature will accommodate various system configurations
Note: Activation of the 1 ohm mode will occur when the output load is 1 ohm. The amplifier will shut down for 15 seconds and then turn back on in the 1 ohm mode. To reset this feature, the power connections must be disconnected for 30 seconds and then reconnected.

• Remote Sub level Control - This port is for the supplied remote gain control that allows adjustment from a remote location .
• Subsonic Filter - This switch will activate the Subsonic Filter Circuit which eliminates unwanted frequencies from 24Hz and below.
• Gain Control - This allows you to set the nominal operating level of the CONNECTIONS
amplifier. The amplifier’s range, 250mV to 2.5V for RCA inputs or 500mV to 5V for speaker level inputs, can accommodate input levels from virtually any brand of source unit.
• Bass Boost Control- The amplifier also features a “high-Q” (i.e. narrow frequency band) Bass Boost circuit. It acts much like an equalizer, with adjustable gain (from 0 to +15dB) fixed at 45Hz. Use this feature to tune lowfrequency audio response to compensate for a less than ideal subwoofer enclosure design. The added boost produces rich, full bass tones that are normally difficult to reproduce in the car audio environment. Note: If Bass Boost is undesired, set Bass Boost to 0dB.
Low-pass Filter Controls
• Frequency (Hz) Selection Control - The crossover frequency is fully adjustable between 55Hz and 550Hz for a wide range of crossover points. Use

this feature, along with your speaker manufacturer’s recommended crossover frequencies, to quickly design a more advanced system
•X-Over Slope Switch - This switch will change the X-Over between a 12db and 24dB per octave slope. The steep crossover slope keeps midrange tones out of the subwoofer and thereby eliminates an unnatural “nasal” tone quality in the audio system.
•Output Mode Switch - This switch is to change the output between lowpass and fullrange. If lowpass is selected, the lowpass filter controls will control the crossover frequency.
•Input Mode Switch - This switch allows you to set the input mode. Stereo input allows full left and right stereo operation. Right (bridged) input allows single channel input for bridged operation. This is especially useful in highpowered systems when using one amplifier for each subwoofer/speaker. L + R (sum mono) allows a stereo input to be summed into a mono output.
•Speaker Level Inputs - These provide connections for a high-level stereo source. In addition, these connections are provided for installations where the source unit’s RCA outputs are unavailable.
WARNING:When using the speaker (high-level) inputs, the Black wire must be grounded at the Radio. Failure to do this will result in noise and improper operation.
