Troubleshooting

8 Dynaudio Focus 110 A

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.
