Audio Ground Box
A good grounding environment is one of the important prerequisites for the best performance of audio equipment. It can help improve sound quality, improve the performance of Signaling in audio equipment and Earthing in power supply systems, and deeply absorb background noise that can disrupt music playback, including electrostatic discharge (ESD), radio frequency interference (RFI) and electromagnetic interference (EMI) ) The resulting "garbage" reduces the noise floor (NoiseFloor), thereby enhancing the signal-to-noise ratio (S/NRatio). Can be improved after use: full frequency dynamics, three-dimensional space sense, sound field positioning, low frequency density, vocal smoothness, instrument separation, layering and transparency.

Where are you going?
For plugging or electrical: grounding terminal or grounding pole
For audio equipment: negative terminal, grounding terminal, housing for signal interface
For the speaker: the negative pole of the signal interface (requires the left and right channel symmetry to be used one by one)

Use suggestions:
One: The grounding box is a passive product and can be used without power connection. The way the grounding box is connected to the power supply is only to absorb the power supply clutter, and it is not connected to the power supply to work.
Second: the grounding box can improve the sound quality, can not replace the grounding wire, its role is mainly used to absorb the clutter purification signal and power supply, not like the grounding of the ground connected to the earth, even if the equipment leaks power All electricity is introduced to the earth.
Three: What is the better place to pick up? Because each person&x27;s equipment circuit is different, the layout and conditions of the power supply in the home are not the same. There is no fixed number, and it is necessary to try more. The equipment to be connected does not have the same effect, which is also the fun of the grounding box.
You can connect the dedicated grounding GND of the device, the metal part of the device housing or the screw (note that the paint on the casing or the casing of the casing will affect the effect, you need to polish the surface layer to improve the conductivity), RCA terminal Negative level (that is, the RCA lotus socket plug copper shell part), the negative level of the speaker (usually the black terminal of the speaker), the ground wire of the power supply (usually marked with ? or G), try to avoid touching, remember. It is recommended to wrap the exposed metal part with the insulating tape and the metal part of the USB terminal.
A set of audio systems generally use 3 to 5 to a dozen depending on the configuration. Each device is recommended to use a junction box for better effect. It is possible to connect multiple grounding boxes with one device. It is not recommended to connect multiple devices with one grounding box. Because they will interfere with each other You can buy one or two trials first, and feel the effect and buy again. Especially if the grounding box is connected to the power supply, it is strictly forbidden to connect to other equipment.
When the number of grounding boxes is less than the number of the devices themselves, it is recommended to first ground the box from the source (CD, record player, digital turntable, etc.)->decoder->pre-stage->post-level->speaker from front to back. It is also recommended that the power strip also use a grounding box.
The principle of the ground box is very simple, that is, the characteristics of the ore are utilized to absorb the electrons, so that the ground portion does not cause a potential difference or an electromotive force due to the movement of the electrons, thereby ensuring that the signal is not interfered or the interference signal is absorbed.
There are three types of grounding: neutral grounding, signal grounding, and shield grounding. The best method of grounding is to connect directly to the earth. The normal neutral line is grounded at the power supply. There is more or less potential difference. The sound system is bound to be affected by this potential difference unless the isolated cow is used or the zero is broken on the bus. Line (which is not safe).
The use of the ground box to simulate the effect of the earth, although not comparable to the real grounding, but it is a neutral solution. After correct grounding, the system noise will be reduced, the background will be darker, the music itself will be clearer, the analysis will be better, and the sensitivity to high frequency and low frequency will be improved. The feeling is high frequency and low frequency extension. Well, the sense of volume seems to increase, the density of the intermediate frequency will increase, and it will feel thick and cohesive, and the amount of full-frequency information will increase. . .
