APX290M/ APX490M OPERATION/INSTALLATION MANUA L MANUEL D'OPERATION/ INSTALLATION MANUAL DE OPERACIÓN/INSTALACIÓN
APX290M/APX490M Power System Amplifier INTRODUCTION English The Clarion APX290M is a full-featured, two-channel amplifier incorporating the following features: • Specially coated circuit boards that resist mold, mildew and moisture damage. • Pulse-Width Modulated (PWM) MOSFET power supply for maximum performance with minimal distortion. • Remote turn-on with "soft start" muting to prevent turn-on "thump".
Operation/Installation Manual DESCRIPTION English The APX290M and APX490M use an unregulated MOSFET power supply for superior sound and output wattage. In addition, a toroid-coil is used to transfer power with minimal performance loss due to heat. To avoid unwanted noise, a double-sided conformal printed circuit board with strategically placed components keeps AM RFI subdued.

Operation/Installation Manual INSTALLATION English This section suggests Mounting and Wiring Precautions for installing the Clarion APX290M and/or APX490M amplifier(s). If you do not posses the necessary tools and installation experience, do not attempt to install these amplifiers. Instead, contact your local Clarion Marine Audio dealer to perform the installation. MOUNTING PRECAUTIONS Prior to mounting the amplifier, make sure it is safe to mount the amplifier in that location.
APX290M/APX490M Power System Amplifier English 7. When creating passage holes for power cables, RCA's cables, and speaker wires, use grommets to eliminate any sharp edges created during drilling. This will protect the wire from being nicked and causing a short circuit. 8. Extra cable can cause signal loss and act as an "antenna" for noise. Use only high-quality RCA cables that are no longer than necessary. 9.

APX290M/APX490M Power System Amplifier SETTING THE GAIN English After completing the installation, follow these steps to set the Gain Control and then perform the Final System Checks. 1. Turn the Gain Control all the way counter-clockwise. 2. Turn the ON/OFF Switch on the source units to the ON position. Set all Tone or Equalization Controls to "flat" positions and turn Loudness off. 3. Play a CD, set the Volume Control at 75% of full level.
Operation/Installation Manual FINAL SYSTEM CHECK English 1. Turn on the source unit. After a two-second delay, slowly increase the Volume Control and listen to the audio. If you hear any noise, static, distortion or no sound at all, check the connections, and also refer to Troubleshooting. Depending on your system design, the levels may become quite loud even at low Volume Control settings. Until you get an "audio feel" of the system's power, use care when adjusting controls. 2.
APX290M/APX490M Power System Amplifier English Pro blem Distorted audio. Solution Gain is not set properly, or damaged speaker cones. Review Setting Gain; inspect each speaker cone for signs of damage (i.e. frozen cone, burning smell, etc.) Pro blem Audio lacks punch. Solution Speakers wired incorrectly, which causes cancellation of bass frequencies. Check polarity of wires from amplifier to each speaker as defined by the system design. Pro blem Amplifier fuse keeps blowing.
