Resumen del manual


If you hear any noise, static, distortion or no sound at all, check the connections and refer to Troubleshooting. Depending on your system, the volume may become quite loud even at low level settings. Until you get an “audio feel” for the system’s power, use care when adjusting the controls. 3. Turn the balance controls to their extreme positions and listen to the results. Audio output should match control settings (audio from the left speaker when balance is left). 4. Increase the volume and verify that the amplifier reproduces the audio at full frequencies without distortion. If you hear distortion check the connections and verify that the gain control is set correctly. Another cause of distortion could be underpowered or damaged speakers. Refer to Troubleshooting.

Troubleshooting No Audio • Low or no remote turn-on voltage: check remote connections at the amplifier and source unit. • Blown amplifier fuse: replace with a new fast-blow fuse (same rating). • Power wires not connected: check battery and ground wiring at the amplifier and check the battery connections. • Speaker leads shorted: check speaker continuity to ground; it should not show a common ground. • Speakers not connected or are blown: check speaker connections at the amplifier; measure coil impedance. Audio cycles on and off • Thermal protection circuits are shutting the amplifier off. • Check the location for adequate ventilation. Consult an authorized Clarion audio dealer. Distorted audio • Gain is not properly set or the speaker cones are damaged. • Review the instructions for setting the gain. Inspect each speaker cone for signs of damage, such as a frozen cone, burning smell, etc. Amplifier fuse keeps blowing • The wiring is connected incorrectly or there is a short circuit. • Review the installation precautions and diagram in this manual and check all wiring connections. Whining or ticking noise when engine on • The amplifier is picking up alternator or radiated noise. • Turn down input gain. • Move the audio cables away from the power wires. • Check the power and ground connections on the amplifier and install an in-line noise filter on the source unit’s power wire. • Check the alternator and/or voltage regulator. Test for a weak battery or add water to the battery. 16 APX2120/APX4240/APX1300 AMPSOwnersManual.pmd 16 2005-12-13, 17:02 7. Glossary Crossover: A device that limits the range of frequencies sent to a speaker or amplifier. dB: decibel, a measurement of the relative difference in power or intensity between two acoustic signals. Equalizer: Component that boosts or cuts sound signal frequencies to improve the quality of the sound. Gain control: gain is the amount of amplification (voltage, current or power) of an audio signal expressed in dB. Hz: Abbreviation for Hertz, a unit of frequency equal to one cycle per second. Octave: the musical principle of dividing sound frequencies into the eight notes of the musical scale. Ohm: unit of electric resistance RCA input/output: port through which sound travels in and out of the system; “RCA” refers to the type of connector, which was first manufactured by the Radio Corporation of America. Slope: how fast the sound gets quieter rated in dBs. The higher the dB number, the faster the frequency drops off. 8.
