User manual CLARION APX401-2

[. . . ] Save your original sales receipt as proof of purchase. 2 Owner's Manual Owner's Manual DESCRIPTION The APX201. 2 and APX401. 2 use an unregulated MOSFET power supply for superior control of output wattage. A toroid-coil transformer yields maximum power transfer with minimal heat loss. Extensive 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, speaker shorts, or improper load conditions occur. [. . . ] Do not overlap frequencies, as this may damage the amplifier. 8 Owner's Manual INSTALLATION This section lists Mounting and Wiring Precautions prior to installing a Clarion APX201. 2 or APX401. 2. These safeguards provide enough detail to complete the installation successfully. If you do not have the necessary skills, do not attempt to install the amplifier yourself. Instead, see your authorized Clarion dealer for installation recommendations. MOUNTING PRECAUTIONS Although the Clarion APX201. 2 and APX401. 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 can 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. Failure to do so may damage your equipment. 9 2 Channel Power System Amplifier 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 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. 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 cause a fire. Connect the amplifier's positive (+) lead via a fuse directly to the positive (+) terminal on the battery. Use red-insulated 10gauge (or larger) wire for the amplifier's positive (+) power lead and the samegauge black-insulated wire for the ground. [. . . ] This warranty does not cover car static or other electrical interferences, tape head cleaning or adjustments, or labor costs for the removal or reinstallation of the unit for repair. The sole responsibility of Clarion Corporation under this Warranty shall be limited to the repair or replacement thereof, at the sole discretion of Clarion Corporation. If it becomes necessary to send the product or any defective part to Clarion Corporation or an authorized warranty service station, the product must be shipped in its original carton or equivalent carton, fully insured, with shipping charges prepaid. Clarion Corporation will not assume any responsibility for any loss or damage incurred in shipping. [. . . ]
