User manual CLARION APX 200.2

[. . . ] We use gold-plated RCA and barrier connectors to ensure the best electrical connection for your system. INPUT CONNECTIONS AND AUDIO CONTROLS The front panel of the APX200. 2 and APX400. 2 both contain connections for RCA Inputs, Speaker Level Inputs and Audio Controls as shown below. The RCAInput Connections are gold-plated RCA Jacks and are labeled as RIGHT and LEFT. Figure 1- 1. Speaker Level Inputs 3 · Gain Control - This allows you to set the nominal operating level of the amplifier. [. . . ] Here are some examples to help plan your own installation. Bridged- Mono Subwoofer System Set X-Over Mode to LP and adjust FREQ to speaker specifications. Figure 3 - In this application the amplifier is bridged for mono operation to drive a subwoofer. 6 2-Channel Full-Range, Satellite, or Subwoofer Stereo System (Set INPUT SELECT Switch to STEREO) Set X-Over Mode as shown. Set X-Over Mode as shown; adjust FREQ to speaker specifications. Set X-Over Mode as shown; adjust FREQ to speaker specifications. Figure 4 - In this application, the amplifier is used in stereo and drives two full-range (or satellite or subwoofer) speakers. NOTE: A passive crossover must be used with satellite speakers. 7 Mixed-Mode Satellite and Subwoofer System (Set INPUT SELECT Switch to STEREO) FREQ (hz) 80 100 125 150 200 L (mH) 8. 0 6. 4 5. 1 4. 2 3. 2 C (uF) 497 398 318 265 199 Set X-Over Mode to OFF. NOTE: Chart values based on 4 ohm speakers. Figure 5 - The amplifier can be configured for a mixed-mode operation. The table provides component values to create a 6dB per octave crossover at specified frequencies. Use components that have a + 5% tolerance and capacitors rated at 100V. Do not overlap frequencies, as this may damage the amplifier. 8 INSTALLATION This section lists Mounting and Wiring Precautions for installing a Clarion APX200. 2 or APX400. 2. Combined with the experience of a professional installer, these safeguards provide enough detail to successfully complete an installation. If you do not have the necessary skills, do not install the amplifier yourself. Instead, see your authorized Clarion dealer for installation recommendations. MOUNTING PRECAUTIONS Although the Clarion APX200. 2 and APX400. 2 both incorporate heat sinks and protection circuits, mounting the amplifier in a tight space without any air movement can still damage internal circuitry over time. Choose a site that provides adequate ventilation around the amplifier. For easy system set-up, mount the amplifier so the front panel controls will be accessible after installation. For the most efficient cooling, mount the amplifier so cool air runs along the length of the fins rather than across them. Do not install the amplifier on plastic or other combustible materials. Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines, brake lines (under chassis) or electrical wiring. If you are not sure of the connections, contact your authorized Clarion dealer. Before installation, make sure the source unit Power switch is in the OFF position. Disconnect the negative (-) lead of the battery before making any power connections. When making connections, be sure that each connection is clean and secure. A secure clean ground connection is critical to the performance of your Clarion amplifier. Use the shortest ground wire possible snd securely connect to the car chassis to minimize resistance and avoid noise problems. Add an external fuse on the amplifier's positive (+) power lead and connect it as close as possible to the vehicle's (+) battery terminal. [. . . ] Check battery and ground wiring at amplifier; also check battery connections. Check speaker continuity to ground, it should not show a common ground. Check location for adequate ventilation; consult an authorized Clarion Audio Dealer. 13 Problem Distorted audio. Review Setting Gain; inspect each speaker cone for signs of damage (i. e. [. . . ]
