What is the common ground? This product is an audio common ground isolator, which is effective for the noise caused by the common ground for the audio source and the receiving device. To put it simply, the ground point of the two electrical appliances is not at the same point. Due to the difference in grounding resistance, noise is transmitted into the electrical equipment through the ground wire to form interference. Because the grounding points of the two devices are different, it is possible to generate common ground noise. In the car audio, there is an audio interference, like the whistling sound, the frequency of this noise will change with the engine speed. Therefore, this product can only eliminate the noise and current sound of the common electricity common product, and can not eliminate the noise caused by other reasons, so you need to confirm the noise source yourself. Determine if noise is caused by common ground: 1. Use the earphone to connect with the car MP3 and the car navigation AUX (3.5mm interface). If the sound heard from the earphone is no noise at this time, it can be confirmed that the noise of the car device is caused by the common ground. 2. Use the audio cable to connect the battery-powered mobile phone, or MP3 (note that the mobile phone and MP3 are not connected to any power supply on the car, such as a telephone), and connect to the AUX of the car's center console, and play the music of the mobile phone. , it can be confirmed that the past noise is caused by the common ground. 3, computer, amplifier, audio, CD: use a passive headset plugged in the computer to listen to the noise, use the phone to insert in the amplifier, audio audition, if you listen to the sound, there is no noise, the basic judgment is caused by the common ground. 4. After starting the car, the installed amplifier has a current sound. In some models, the throttle is larger and the current is louder. | ![]() B08BRSQ7JY Price: $7.99 Score: 7.407 Category: Electronics Rating: 4.3 Votes: 687 Find similar productsJABINCO Ground Loop Noise Isolator,for Car Audio/Home Stereo System with 3.5mm Audio Cable (Black).

Specifications: 1)Size: 7*5*2.5cm (LWH) 2)Suitable for Speaker Power: 400W or lower 3)Suitable for Speaker Impedance: 4 to 16 ohm With 4 jumpers onboard to optimize your audio effect: Jumper A, B for bass; Jumper C, D for treble. Details about jumpers: Jumper A, B are used to control audio effect of bass range. A for lower limit while B for upper limit of the bass audio range. For some speakers, when Bass is turned up too much, the speaker will show distortion. When that happens: we remove the jumper cap of jumper A to limit super low Bass to bring distortion lower. When we remove the cap of jumper B, Bass is increased while cap of Jumper B is on, Bass is decreased. Jumper C and D are used to control Treble range. When cap of both jumper C and D are on, the sound of treble is loudest. When only cap C is on, the treble sound is lower. When only cap D is on, further lower. When both caps of C and D are removed, there is no treble sound. (Generally speaking, with the four jumpers, you'd sooner or later find your best sound effect. Anyway, all effects still depend on your actual test.) How to use the splitter board: First connect as per our diagram above (Treble, Low, Input), connect to speaker, seal air gap, we can begin to hear music while optimize. Normally we use jumper A and let B idle. For jumper C and D: we need to hear the actual effect of treble. A general formula is: A+D=better Bass; A+C=clear Treble and Bass; A+CD=clear Treble and Bass (the overall effect inclined towards Treble); AB+CD=more mediant frequency. When Bass effect is unnecessarily high, we can remove cap A. Please optimize until you think the sound is best, and then fix the board with your speaker unit. |
