Setting The Crossover; Setting The Bass Boost; Final System Checks - Clarion APX2121E Benutzerhandbuch

Setting the crossover

Clarion amplifiers feature fully-adjustable crossovers.
1. Using the X-Over mode switch, select either LP (low pass) or HP (high pass) or
OFF for full range.
2. Using the Freq (Hz) control, select the frequency.

Setting the bass boost

1. Initially set the bass boost control to off.
2. Listen to a variety of music styles (for example, rock, rap, etc.) and switch the
bass boost control on until you notice an increase in low bass response.
CAUTION!
If you hear a pop caused by speaker overexertion, lower
the bass boost to prevent damage to the speaker.

Final system checks

1. Start the engine and turn on the source unit.
2. 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 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.
