Noise-Free Sound Audio Isolator for Common Ground Interference
Elimination
1.Product Description
Isolation of common ground interference between devices,
elimination of current sound, filtering effect, sound noise
reduction and so on.
Determine whether the noise is caused by common ground:
1, the use of headphones and car MP3, car navigation AUX (3.5mm
interface) connected, if there is no noise heard from the
headphones at this time, you can confirm that the noise of the car
equipment is caused by common ground.
2, use the audio line to connect the battery-powered mobile phone,
or MP3(pay attention to the mobile phone, MP3 do not connect with
any power supply in the car, such as the phone) and the AUX of the
car console, and play the music of the mobile phone, so that there
is no noise, you can confirm that the noise in the past is caused
by common ground.
3, computer, power amplifier, audio, CD: the use of passive
headphones inserted in the computer to listen to no noise, the use
of mobile phones inserted in the power amplifier, audio test, if
there is no noise between the two, the basic judgment is caused by
common ground.
4, after starting the car, the installed power amplifier has the
current sound, some models will also appear the larger the
throttle, the larger the current sound, this product can solve this
problem.
5, there is a current sound between the power amplifier and the
speaker or speaker, you can install this product between the power
amplifier and the speaker.
6, the laptop computer connected to the projector at the same time
to the power amplifier to produce noise, you can connect the laptop
adapter power supply or battery, at this time unplug the power
amplifier noise disappeared, or unplug the projector the same noise
disappeared, then you can add a common ground isolator between the
headset hole and the power amplifier to eliminate noise.
