2. Mikrofonposition: Place the microphone in the primary listening position (e.g., driver's headrest).
3. Tuning einleiten: Follow the instructions in the full user manual to activate the auto-tuning sequence. The amplifier will emit a series of test tones.
4. Fertigstellung: Once the tones cease, the tuning process is complete. The amplifier's internal computer will have applied a 40-band equalizer and a 24dB crossover to each speaker, optimizing the soundstage and tonality.

The auto-tuning feature significantly improves sound clarity and realism, revealing the full potential of your speakers.
