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. Atoroid-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
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.

DESCRIPTION

INPUT CONNECTIONS AND AUDIO CONTROLS

The front panel of the DPX1000.2 contains connections for RCA Inputs,
Speaker Level Inputs and Audio Controls as shown below.

The RCA Input Connections are gold-plated RCA Jacks and are labeled as
RIGHT and LEFT.

• 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
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 RCAoutputs 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.
