The following is a list of features: · Full frequency response with low distortion and exceptional signal-to-noise performance. · Advanced circuitry design features bridgeable outputs for use in a variety of applications. · Independent electronic crossovers, each with a 12dB (12/24dB - DPX1001.1) per octave slope and full adjustment range from 50Hz to 5.8KHz, (50Hz to 580Hz - DPX1001.1) to aid in audio system design. · Bass boost circuit to reinforce low frequency signals that may be lost due to subwoofer box design. · Adjustable input level controls with ground loop isolation, accepting a wide range of input signals. · Remote turn-on with "soft start" muting to prevent turn-on "thump". · Protection circuits for overheating and speaker shorts. · 2-ohm load capable to drive a variety of speaker systems. · Gold-plated input/output connectors and an external automotive- type fuse. · Aluminum heat sink for efficient heat dissipation. · Low profile, compact size to accommodate space limitation. DESCRIPTION 3 apx-dpx-update.qxp 8/18/2004 8:46 AM Page 4 APX640.4/640.2/320.2/DPX1001.1 INSTALLATION This section lists mounting and wiring precautions prior to installing the Clarion amplifier. These safeguards provide enough detail to complete an installation successfully. Do not attempt to install the amplifier yourself, if you do not have the necessary skills. Instead, see your authorized Clarion dealer for installation recommendations. MOUNTING PRECAUTIONS Although the Clarion amplifiers incorporate heat sinks and protection circuits, mounting the amplifier in a tight space without any air movement will result in damage to the amp's internal circuitry over time. Choose a site that provides adequate ventilation around the amplifier. For easy system setup, mount the amplifier so the frontpanel controls are accessible after installation. In addition, observe the following precautions: 1. For the most efficient cooling, mount the amplifier so cool air runs along the length of the fins rather than across them. Remember, any moving air will dissipate heat. 2. Mount the amplifier on a rigid surface. Avoid mounting to subwoofer enclosures or areas prone to vibration. Do not install the amplifier on plastic or other combustible materials. 3. Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines, brake lines (under chassis), or electrical wiring. WIRING PRECAUTIONS Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion dealer. 1. Before installation, make sure the source unit's Power switch is in the OFF position. 2. Disconnect the negative (-) lead of the battery before making any power connections. 3. When making connections, be sure that each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing. Failure to do so may result in damage to your equipment. PRECAUTIONS 4. A secure, clean ground connection is critical to the performance of your Clarion amplifier. Use the shortest ground wire possible and securely connect to the vehicle's chassis to minimize resistance and avoid noise problems. Be sure to clean off any paint prior to making this connection. 5. Add an external fuse on the amplifier's positive (+) power lead and connect it as close as possible to the vehicle's (+) battery terminal. Use a fuse rated to the total current consumption of the amplifier(s). Adding an external fuse will protect the electrical system from short circuits that can result in a fire. 4 apx-dpx-update.qxp 8/18/2004 8:46 AM Page 5 Owner's Manual INPUT CONNECTIONS AND AUDIO CONTROL Clarion amplifiers contain connections for RCA Inputs and Audio Control as shown below. 1 INPUT L 4 2 0 15 6 3 55 550 Hz 8 CROSSOVER 110 9 5 7 APX320.2 HIGH Level OFF HP LP L & R (MONO) BRIDGED (R IN) L STEREO R 240 dB 330 R 4V-8V 2V-4V 0.2V-2V FREQ RANGE X1 X10 Figure 1-1 APX320.2 Input Connections and Audio Control 1 INPUT L 4 2 0 15 6 3 55 550 Hz 8 CROSSOVER 110 9 5 7 APX640.2 HIGH Level OFF HP LP L & R (MONO) BRIDGED (R IN) L STEREO R 240 dB 330 R 4V-8V 2V-4V 0.2V-2V FREQ RANGE X1 X10 Figure 1-2 APX640.2 Input Connections and Audio Control CONNECTIONS 5 1. 2. 3. 4. 5.

The Gain Controls provide a wide adjustment range to accommodate output levels from any source unit brand. Precise Frequency Selector The filter frequency markings on the front panel of the amplifier are for reference purposes. If you would like to select the filter frequency with a higher level of precision, consult the chart in Figure 3 on this page. This chart gives you a more accurate frequency for each of the forty-one detented positions of the frequency selection control. · Gain Controls with Selectable Input Voltage There are 2 settings for the "Gain" that must be adjusted in order to maximize the power output of the amplifier. The first step is to select the proper input voltage and the second step is to adjust the Gain dial. · Input Voltage Selector A wide range of signal input voltages can be accommodated by the APX320.2, APX640.2, APX640.4 and DPX1001.1 input section (200mV - 8V). This wide range is split up into three ranges, Figure 2, accessible via switches located in the "Gain" of the amplifier. The "0.2V-0.6V" position on the switch selects an input sensitivity range between 200mV and 600mV, the "0.6V-2V" position on the switch selects an input sensitivity range between 600mV and 2V and the "2V-8V" position on the switch selects an input sensitivity range between 2V and 8V. This means that the "Gain" rotary control will operate within that voltage window. If you are using an aftermarket source unit with RCA outputs, make sure you select the proper voltage selection range. For example, if the RCA voltage of the aftermarket head unit is rated at 4 volts, set the switch at "2V-8V". Figure 3 - Detent Chart 7 CONNECTIONS apx-dpx-update.qxp 8/18/2004 8:46 AM Page 8
