Please tell me: how to adjust the car audio center, high, bass ah?

1)First of all, all the additional functions of the car host will be restored to the factory state, and then the high, middle and bass all in the center, of course, left and right balance is the same.

2)Set the volume of the amplifier (GAIN) in the lowest position (MIN)

3)Set the FILTER in OFF

4)Set the CROSSOVER in the lowest position

5)The subwoofer amplifier is also handled in the same way

First step: Host debugging

Open the host, play some high-fidelity vocal disk or bass dynamics of some strong disk, the volume will be twisted to half or 3/5 position, this is easier to make the bass and the front of the sound field of the bass and midrange articulation, more likely to produce a full-bodied bass.

The second step: the front sound field debugging

We will first CHANNEL-1/2 GAIN twisted until the sound is very large, or you can accept the maximum sound can be, the next step we will be the host of the volume off small, into a vocals disc or a low-frequency strong some of the disc, and then the host of the volume slowly open up until the normal listening than you are a little bigger than the sound until, well, this time! You should listen carefully, whether the vocals are clear? Will there be nasal? Or the sound of the bias Meng? If the sound is clear without nasal sound, or low-frequency out of the elasticity is very good, no trailing "buzzing" sound, low-frequency one by one not hairy, then congratulate you, your front door sound insulation shock absorption installation of the basic full points, in this state, your front door bass will play the best state.

The third step: host debugging

Often, the host volume increase, there will be a human voice nasal, like a cold, or feel unclear pronunciation, low-frequency issued by the time there will be a "buzzing" sound, these conditions are the so-called *** vibration of the sound affects the clarity of the sound. *** vibration will cancel a lot of details of the sound, the sound of the low-frequency slowdown, the value of your 5W audio equipment into a 1W sound.

Acoustic damping is a means, in addition, we can host or amplifier on the CROSSOVER (cut-off frequency) to reduce the chances of this sound, we look at the figure, you can try to FILTER (filter settings) dialed to the HP (high-pass) position, the CROSSOVER (cut-off frequency) knob twisted to 60HZ70HZ80HZ90HZ or even 100HZ, FILTER (filter settings) and CROSSOVER (cutoff frequency) are used in combination, FILTER (filter settings) only in the state of LP or HP, CROSSOVER (cutoff frequency) adjustment will have an effect in the case of the sound is not clear, we try to Rotate the CROSSOVER (cut-off frequency), see twisted to the position of the human voice on the disappearance of nasal or low-frequency no "buzz" sound, if in the vicinity of 60 ~ 70HZ, then, congratulations, sound insulation damping or do a good job.

The fourth step: the rear sound field tuning

Whatever the state of the front sound field, the rear sound field should be set in the HP state, CROSSOVER (cutoff frequency) twisted to 150HZ near, then, the host volume twisted up, in the normal volume, the amplifier will be pushed to the rear of the sound field of the GAI
