HiFi Audio Grounding Box Power Purifier Noise Filter for Amplifier / Speakers

Description: Ground box principle: The characteristics of ore are used to absorb electrons so that the grounded part of the device will not cause potential difference or electromotive force due to the movement of electrons, to ensure that the transmission of signals is not disturbed. When the floor box is used correctly, it can effectively make the music clearer, the mid-frequency density increases, the high-frequency and low-frequency extension is good, and the sound becomes more natural and soft. Internal materials: Using 16 kinds of pure natural rare high-energy ores, we have continuously optimized a variety of precious metal-semiconductor materials inside, three-dimensionally covering the collector silver conductor, the connecting wire is made of single-crystal pure copper silver-plated Add to Favorites Seller Join newsletter New Arrival Ending Soon View Feedback About Us Contact Us View All Categories Nobsound & Douk Audio Add-on Items US Warehouse UK Warehouse DE Warehouse AU Warehouse Digital Amplifier Tube Amplifier Audio Amplifier Preamp & Phono Stage Headphone Amplifier DAC & Audio Adapter Audio Splitter/Switcher Audio Processor Audio Player Music Spectrum & Clock Empty Chassis Record Player & Turntable Part Power Supply Vacuum Tubes Hi-Fi Speakers Hi-Fi Cable Transformer Radio Communication Audio Accessories Other Home Feedback Save Seller New Listed Ending Soon Contact us Store Category Nobsound & Douk Audio Add-on Items US Warehouse Add-on Items Amplifier Preamp & Phono Stage Headphone Amplifier DAC & Audio Adapter Audio Splitter/Switcher Music Spectrum & Clock Audio Accessories Other UK Warehouse Add-on Items Digital Amplifier Tube Amplifier Hi-Fi Amplifier Preamp & Phono Stage Headphone Amplifier DAC & Audio Adapter Audio Splitter/Switcher Audio Processor Music Spectrum & Clock Record Player & Turntable Part Audio Board & DIY Kit Audio Accessories Other DE Warehouse Add-on Items Digital Amplifier Tube Amplifier Hi-Fi Amplifier Preamp & Phono Stage Headphone Amplifier DAC & Audio Adapter Audio Splitter/Switcher Audio Processor Music Spectrum & Clock Aluminum Chassis Record Player & Turntable Part Audio Board & DIY Kit Radio Communication Audio Accessories Other AU Warehouse Add-on Items Amplifier Preamp & Phono Stage Headphone Amplifier DAC & Audio Adapter Audio Splitter/Switcher Music Spectrum & Clock Audio Accessories Other Digital Amplifier Multi-Function Mono Channel 2.0 Channel 2.1 Channel 4.0 Channel 5.1 Channel Tube Amplifier DIY Kit Hybrid Amplifier Mini Tube Amplifier EL34 Tube Amplifier KT88 Tube Amplifier 300B Tube Amplifier Other Tube Amplifier Audio Amplifier Mini Amplifier Integrated Amplifier Power Amplifier Audio Board & DIY Kit Preamp & Phono Stage Tube Preamp Digital Preamp Phono Preamp Passive Preamp Audio Board & DIY Kit Headphone Amplifier Mini Headphone Amp Desktop Headphone Amp Portable Headphone Amp Tube Headphone Amp DAC & Audio Adapter Audio Adapter USB DAC Bluetooth Receiver/Transmitter Digital Interface Audio Board & DIY Kit Audio Splitter/Switcher Speaker Switcher Bluetooth & XLR & MIC 2 Way 3 Way 4 Way Multiple Way Audio Processor Guitar Effects Equalizer Audio Mixer Noise Isolator Audio Player Digital Player Record Player CD Player Portable Player Music Spectrum & Clock Analog VU Meter Tube Sound Level Meter LED Sound Level Meter VFD Audio Spectrum LED Clock Nixie Tube Clock VFD Tube Clock IPS Nixie Clock Oscilloscope Tube Clock Board & DIY Kit Other Empty Chassis Small-sized Medium-sized Large-sized Personalized Record Player & Turntable Part Set-up Transformer Record Weight & Clamp Cleaning Kit Scale Gauge Platter Mat Dust Cover Needle Other Power Supply Linear Power Supply Switching Power Supply Power Supply Filter USB Charging Hub Board & DIY Kit Vacuum Tubes Shuguang Tube PSVANE Tube Tube Socket Tube Tester Probe Hi-Fi Speakers Frequency Divider Speaker Unit Hi-Fi Cable RCA Audio Cable 1/8 & 1/4 Stereo Jack Cable Speaker Cable USB Cable Optical Fiber Cable Conversion Cable Dock Cable Other Transformer Toroidal transformer Output Transformer Other Radio Communication Tesla Coil Transmitter & Receiver Signal Generator Antennas & Tuners Shortwave Radios Ham Amateur Radio Audio Accessories Volume Controller Mount Stand Bracket Feet & Pads Op Amp Headphone Current Meter Other Other Join Our Newsletter Receive our email newsletters about new items and special promotions!

It is recommended to buy a large size, if you need to use it in a narrow and long space, you should buy a medium-sized extended version, and if you use low-power desktop devices such as amps, it is recommended to buy a medium-sized version. Features Ground box principle: The characteristics of ore are used to absorb electrons so that the grounded part of the device will not cause potential difference or electromotive force due to the movement of electrons, to ensure that the transmission of signals is not disturbed. When the floor box is used correctly, it can effectively make the music clearer, the mid-frequency density increases, the high-frequency and low-frequency extension is good, and the sound becomes more natural and soft. Internal materials: Using 16 kinds of pure natural rare high-energy ores, we have continuously optimized a variety of precious metal-semiconductor materials inside, three-dimensionally covering the collector silver conductor, the connecting wire is made of single-crystal pure copper silver-plated Teflon wire, and the joints are made of Gold-plated copper. Materials are used at all costs, just to ensure excellent quality. How to use: ① for plug or filter: ground wire terminal or ground wire one pole ②For audio equipment: connect the negative pole of the signal interface, the ground terminal, the shell, etc.③Used for speakers: connect to the negative pole of the signal interface (need to connect one left and one channel symmetrically) It can be connected to the special grounding place of the device, the metal part, or the screw of the device shell (note that the paint on the chassis or screw will affect the effect, and the surface needs to be polished to improve the conductivity), the negative stage of the RCA terminal, the speaker's Negative stage, the ground wire of the power supply (try to avoid touching it after wiring, it is recommended to wrap the exposed metal part with insulating tape), and the metal part of the shell of the USB terminal. Simple design: The wooden shell is clean and simple and easy to use. After use, it can comprehensively improve the full-frequency dynamics of the sound, sound field positioning, instrument separation, layering, and transparency.
