This product is an audio common ground isolator, which is effective for the noise caused by the common ground of the sound source and receiving equipment.
On the car audio, there is an audio interference, like a whistle like a whistle. The frequency of this noise will change with the speed of the engine. Therefore, this product can only eliminate the noise and current sound caused by the common electricity and common ground products, and cannot eliminate the noise caused by other reasons.
.Description:
Product Category:Bluetooth receiver
1. Eliminate the hum: eliminate the hum noise caused by the ground loop when the audio source and (some car speakers/home audio systems) use the same power supply, so as to achieve clear music enjoyment, and the wonderful bloom from then on;
2. Pure sound quality: no damage to rock music, giving you a better experience, can be used on mono;
3. Easy to use, just plug and play, no battery]: small and portable, this gadget does not take up too much space, and it is easy to take away;
The problem of noise can not be eliminated: u2460Noise caused by non-common ground, this paragraph can not be filtered, such as electromagnetic interference, etc., be sure to confirm the source of the noise before buying, u2461Because everyone has different expectations for the isolation effect, the senses are different, some customers think Good, some customers feel bad;
To determine whether the noise is caused by common ground: 1. Use headphones to connect to the car MP3 and car navigation AUX (3.5mm interface). If the sound heard from the headphones is no noise at this time, you can confirm that the noise of the car equipment is due to the common ground Caused by land. 2. Use the audio cable to connect the battery-powered mobile phone or MP3 (note that the mobile phone and MP3 should not be connected to any power supply in the car, such as a telephone) and connect to the AUX of the center console of the car, and play the music of the mobile phone, so there is no noise , You can confirm that the previous noise is caused by the common ground. 3. Computer, power amplifier, audio, CD: use passive headphones to plug in the computer to check whether there is noise, and use a mobile phone to plug in the power amplifier and audio to test, if there is no noise in the separate test, the basic judgment is caused by the common ground. 4. After starting the car, the installed power amplifier has a current sound, and some models will also have a situation where the throttle is greater and the current sound is louder. This product can solve this problem. 5. There is galvanic sound between the power amplifier and the speaker or sound, you can install this product between the power amplifier and the speaker. 6. When the laptop is connected to the projector and the amplifier is connected to the power amplifier, there will be noise. You can connect the adapter to the power supply or use the battery through the notebook. At this time, the noise will disappear when the power amplifier is unplugged, or the noise will disappear when the projector is unplugged. Add common ground isolator to eliminate noise;
