Clarion APA5241 User Manual

OPERATION/INSTALLATION MANUAL
♦ To avoid possible noise problems, run the amplifier’s positive (+)
power lead along one side of the vehicle to the battery. Run the remote
turn-on wire and RCA audio cables down the center, and route the
speaker wires along the remaining side. If wires must cross, run them
perpendicular to each other.
♦ When creating passage holes for the power wire, use grommets to
eliminate any sharp edges created during drilling. This will protect the
wire from being nicked and causing a short circuit.
♦ 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 to make
a direct connection with the source unit or equalizer.
♦ Depending on the type of system being installed, refer to the examples
in Figures 5 through 8 (starting on page 8) for information on wiring
and setting the operation mode.
SETTING GAIN
1. Turn all GAIN controls to their minimum (far left) positions. Also set
BASS EXTENDER to 0 dB, and slide the FILTER switch to OFF.
2. Turn the vehicle’s ignition switch to the ON position. Then turn the
ON/OFF switch on the source unit to the ON position. Set all tone or
equalization controls to “flat” positions and turn loudness off.
3. Play a CD or tape and set the volume control at 75% of full level.
4. Verify that the POWER indicator on the amplifier comes on.
NOTE: When using an equalizer, set its frequency controls to “flat. ”
5. Set the fader control (on the source unit) to full front and slowly
increase the GAIN CHI/2 control for the front amplifiers (channels 1
and 2). Stop when you hear a slight distortion of audio. Set the fader to
full rear and repeat this step for the rear amplifier using the GAIN
CH 3/4 control.
