Product Description

Why Use Ground Box?

a: There are many kinds of electromagnetic interference in the air, and all kinds of interference have a great negative impact on our audio system. b: Due to the shared ground wire, interference from other electrical appliances flees from the ground wire to our system c: The equipment we use will also produce electromagnetic interference

What is the role of Ground Box?

Ground Box has three main functions a: The background tranquility of the sound can be improved, and the details will naturally be rich when the background is quiet. b: It can improve the sense of space of the sound field. After the sense of space is enhanced, the sound field is of course more open, and the positioning of human voices and instruments will be clear and natural. c: It can improve the density and roundness of the mid-frequency. If the mid-frequency is improved, the human voice will be sweeter and more delicate.

Design Ideas of AS-804 Ground Box

Different from power grounding, AS-804 Ground Box is a specially designed ground wire to realize the ground connection of audio equipment. Among many factors, the equipment achieves the best performance, such as eliminating the bottom noise of the speaker, the influence of magnetic fields, and the discharge of capacitors to create a stable and non-vibrating grounding system. If you can effectively remove noise, scattered magnetic field currents, and the swing of pits before the sound is contaminated, you no longer need other synthesis filters or power processors and similar devices. Most power processors have The filtering function will weaken the high and low frequencies and reduce the system dynamics. AS-804 Ground Box adopts active shock absorber design (the bottom is equipped with Rosenthal ceramic beads, the world’s first Ground Box with shock absorber function), Teflon 5N grade sterling silver cable. Small and exquisite. The effect of eliminating audio power noise is very obvious, especially for projection and power equipment (CD player, vinyl player, Blu-ray player, front and rear stage, decoder, workshop, amplifier). . The Ground Box is made of special alloy as the outer shell (9 cm in diameter), and its performance is more stable than ordinary wooden shell. Because the wooden shell material absorbs moisture in wet weather, the performance deteriorates and this floor box will not be affected by this. During the debugging process, it was found that it is extremely sensitive to shock absorbers, so it has made a shock absorber treatment like shock studs on its bottom, with 5N pure silver wire ears. Just connect the wire ears to the screws on the outside of the equipment, and you can feel the peaceful background of music and excellent transparency. Suitable for power ground plug and all equipment use.

Instructions for use

1. Ground Box can be used without power supply. 2. Ground Box cannot replace the real ground wire. It can only improve the sound and picture quality. Its function is mainly to absorb noise. It cannot be the same as the ground wire that is actually connected to the earth. Electricity is introduced into the earth. 3. Where does it work well? Because everyone has different equipment circuits and different power supply layouts at home, you need to try more. The place where the effect is the most obvious, just connect it to that place. This is also a fun place for this Ground Box. 4. See if there are any free sockets on your machine, it is recommended to buy which line to plug in. It is recommended to start with the ground box of the audio source (CD, turntable, digital turntable, etc.) decoder, preamplifier, postamplifier, and speaker from front to back. The power strip should also be connected to a Ground Box. 5. It is better to use one Ground Box for one device. You can connect multiple Ground Boxes to one device. It is not recommended to connect multiple Ground Boxes to one Ground Box because it will interfere with each other and affect the effect.
