Troubleshooting

To adjust the frequency response:
1. First check the overall setup of your audio components (e.g. the
preamplifier sound controls) and the speaker position. Note that
slight changes in the speaker position could improve the sound
quality dramatically. Setting the filter switches should be your last
steps in fine tuning the sound.
2. Play music covering a wide audio frequency range.
3. Compare your sound experiences to the cases explained in Table
on page 8 and set the filter switches accordingly.
Note: Due to the numerous combination possibilities of audio
components, acoustical environment and speaker positions the
explanations can just apply to a few cases. Your own personal
listening experience will be the final benchmark.
