How to Adjust the Focus Audio System?
1 Answers
First, reset all additional functions of the car's main unit to factory settings. Then, set the treble, midrange, and bass to the middle position, and do the same for the left-right balance. Set the amplifier's volume to the lowest level, FILTER to OFF4, and CROSSOVER to the lowest 5. For main unit debugging, play some high-fidelity vocal discs or discs with strong bass dynamics, and adjust the volume to slightly over half or 3/5 of the maximum level.
