Four tuning methods of car audio

Tuning skills of car audio: Method one, crush high frequency, create a clear, spatial and pressure-free high-frequency effect. A certain attenuation of the high frequency is carried out. Due to the masking effect, the delicacy and sense of space of the high-frequency band can be highlighted after the low-end attenuation. Method two, tighten the ultra-low frequency to create a refreshing and clean ultra-low frequency effect.

The best adjustment methods for car audio include host debugging, front sound field debugging, rear sound field tuning, bass adjustment, and equalizer adjustment. The specific contents are as follows: host debugging. Open the host and play some high-fidelity vocal discs or bass dynamic and stronger discs.

Adjust the amplifier channel switch function of the front sound field to the HPF position. PRE-ADjust THE HPF FREQUENCY OF THE FRONT SOUND FIELD AmPLIFIER TO ABOUT 60-70HZ. Adjust the Gain (volume) of the front sound field to the minimum. Adjust the amplifier channel switch function of the rear sound field to the HPF position.

vehicle tuning setting parameters

1,: You can choose DSP amplifiers. Now there are many DSP amplifiers on the market that are very convenient and intelligent, and mobile phones and PCs can be tuned.Some even do not need to be tuned at all, such as our Angle Voice car sound machine, intelligent tuning, and automatic selection parameters to adjust the high school bass according to the model.

2. Press the SET key to enter the sound effect and clock setting interface. The optional adjustment sequence is BAS-TRE-FAD-BAL-EQ-Hourset-Minuteset-OFF-BAS. Depending on the model configuration, your vehicle may not be equipped with all of the above functions. Press the 7 and 6 keys to adjust the specific sound effect value.

3. Tune the whole sound field forward by 2 or 3 squares; high bass + - do not exceed 3; for example: treble +1, bass + adjust the bass of the entertainment setting to 8-9 (if the low frequency is distorted, adjust it smaller) the middle tone to 2-3, the treble to 5-6, the left and right equalization to the middle, balance the front and back Also adjust to the middle.

How to tune the car audio?

1.: You need to find an experienced master to help you tune, because the car audio is a three-point equipment and seven-point debugging, so the tuning step is really important. 2: Don't care about other people's opinions. What you like is the best, so you must be present when tuning.

2. Car audio tuning steps: adjust the filter in the car audio to the high-pass (hp) position. Adjust the cut-off frequency (crossover) on the host to about 60hz-100hz. If the sound of the stereo is impurities or unclear, you can adjust the cut-off frequency of the stereo back and forth.
