Audiobits Mains Noise Eliminator

If you do not like series noise filter, such as power regulator, isolation transformer, voltage regulator, mains filter, power distributor with filter, and etc, then you've come to the right place.

We are pre-launching the Audiobits Mains Noise Absorber (AMNE)! Audiobits Mains Noise Eliminator is a parallel noise eliminator device. Just plug it into any AC outlet, from 90Vac to 250Vac (universal), and it will automatically clean up the noise and free your HIFI system from noise.

Since HIFI equipment does not go through AMNE (Audiobits Mains Noise Eliminator), it will not restrict the dynamics of the system. 

Check out the video below to witness it yourself using a simple test.

Before AMNE is plugged in, we are measuring about 850mV of noise from the Line EMI Meter. Once AMNE is installed at the adjacent socket, the noise floor dropped to about 500mV. You can hear attenuated noise from the Line EMI meter too. Once the AMNE is removed, the noise floor is back to 850mV. 

The noise eliminated by Audiobits Mains Noise Eliminator (AMNE) is effective from DC till 100Mhz range. 

Applications* electrical and electronic equipment
* consumer goods, such as audio and video equipment
* machinery 
* household equipment
* various noisy environment/applications 

Connection methods

USB Power Supply Cleaner

USB Power Supply Cleaner

The USB Power Supply Cleaner (and strengthener too!) will clean up the USB supply noise and provide act as a power bank to supply back current when the devices connected to the USB ports or USB chain in the PC needs them. 


Why do we need to clean up the PC / Computer Audio System USB supply and strengthen it? For those in PC industry, they would have known. PC, desktop or notebook are commodities. The margin is so low that it every cents count! The whole system will be optimized in such a way that it will work and function correct at a certain margin, but not in a way that it is good for audio reproduction, with ultra clean environment and ultra low noise for highest SNR and lowest distortion, unlike the audio world, where everything is overkill and built for 200% - 1000% headroom. 

Therefore, unless you have a custom built PC just for computer audio system use, the motherboard will be designed the same. What we need, is to provide and external source of cleaning and additional clean supply to substantiate or support the audio application requirements. 

A USB Power Supply Cleaner will look like and ordinary power bank (below is just a sample but not the actual unit), with USB A or B output ports to connect to your PC. It, will have circuits to lower the supply noise, and provide auxiliary or supplementary power to the USB power rails. 

This USB power supply cleaner should be used together with USB ground cleaner for the best effect! 

Price:
- Level 0 (entry), RM300/unit
- Level 1 (intermediate), RM500/unit
- Level 2 (audiophile/advance) RM800/unit

Note: USB cable is NOT bundled. Audiophiles should get audiophile USB cables from certified USB cable manufacturers for best effects, the shorter the better!

USB Ground Cleaner

USB Ground Cleaner

We have a converter cable for using the ground box with USB ports for PC or Computer Audio System. The converter cable will have Y-spade or banana plug at one end, and a USB A or USB B head on the other end to connect to a PC / Computer. 

Why do we need to clean up the PC / Computer Audio System ground? For those in PC industry, they would have known. A notebook or desktop PC is made up of tens and hundreds of individual power supplies on the motherboard to power tens and hundreds of IC (integrated circuits / chips / SoC / CPU). In order to make them small, light, efficient and cheap, they are mostly made up of switching regulators that generates noises everywhere in the PC. On top of that, the high speed signals from the communications between those circuits and chips generate noise too. All these will be riding on the ground of the USB port and being transmitted to your audio system. We definitely need to find ways to draw these noises away and using ground boxes or ground cleaner will be one of the effective means of doing so.
 The converter cable will be something similar to this below (copied from internet) but with better quality audiophile banana plugs or Y-spade and audiophile cabling. 

The USB Ground Cleaner using 3io Blackbox or Audiobits Ground Box will help you clean up the noise riding on the ground at the PC / computer audio system by drawing them all away, giving you darker background, cleaner highs, less harshness and clearer soundstage.

• Price inclusive of Audiobits Ground Box and interconnect wire. Interconnect wire with IEC plug requires additional RM50, purchased separately.
• Tips: keep the wires to be <0.5M 

HIFI is a very complicated and magical item. Something that does not even sound logical scientifically, actually works. And, this has been proven again and again. Audiobits Ground Box, is one of them! Lots of audiophiles tried and provided feedback that it brings improvement to sound, as well as video! The textures and contrast had improved upon application of this device. 

Examples:

• After connecting this to the digital ground, the sound gets smoother, with very obvious darker background. Soundstage extended further to the back. The sound is cleaner yet with no lost in body.
• Overall, the changes is very obvious. The highs get rounder, with more harmonics. Background got quieter. The most important thing is, it has more relaxed and at ease sound. The character did not change, the tonality has improved. Well worth the money.
• It lowers the system distortion. The frequency extensions are clearer. The background got slightly darker.
• Blacker black, better low and high extension. Mids improved. Instruments have better separation. Dynamics improved.
• Sound got more delicate, more refined. Everything are delivered clearly, with more sweet and prominent vocals, probably because of better dynamics, lower noise floor.
• Vocals are brought more forward into the room, more details, and soundstage solidified. 
• When it is connected to the output ground, and the chassis, in overall, it presents a quieter background. Mid-low frequency improvement are more obvious. More details are revealed, a positive outcome. Once the ground box is positioned, please do not move it or else it needs some time to stabilize.

We are not afraid of showing you the internals. You can take a look and see if it is worth your money. Do not judge the look by itself. What's more important is the improvement it brings with such little investment. 

Ground box is not invented by us. It is by some manufacturers overseas, on basis of electrical and physics, with proper explanation behind their products. We tried, and it in deed is effective. Such products are sold at a very high price. Upon analysis, the materials are not that expensive itself, and the whole composition is not that complex either. Therefore, we've come up with an inexpensive version - Audiobits Ground Box! 

Special notes:

1. This box is not guaranteed to work. Everyone's systems are different and the sensitivity to this is dependent on the equipment connected. It could have worked wonders, and vice versa. 
2. 7 days money back guarantee. Buyer pays return shipping to us. Items must be returned in original conditions and original packaging that is re-sale-able. 
3. If you are those skeptical audiophiles, save your postage, do not buy. Negative placebo effects apply. 

Tips:

1. Try different ground wires
2. Try different grounding points
3. Try different ground lengths
4. Try different support for ground box (spikes, rubber, foam and etc)
5. Try different number of ground boxes connected

Bundled cable is 4mm2 silver plated copper with Teflon insulation. Audiobits ground box is very sensitive to cables. We tried many, and silver plated copper is the best, although cost is considerably higher. 

Note: the alligator clip is removable. The cable is with Y-plug and banana plug at the other end. You can connect it either ways, according to the situation.

Audiobits Ground Box with different grounding interconnects. 

Application notes:

1. Audiobits Ground Box is for noise absorption. Ground box do not need to be powered electrically. 
2. Audiobits Ground Box CANNOT replace real ground. 
3. Audiobits Ground Box can be connected to any ground points in the system. Effect varies due to different grounding method from the connected equipment.
4. If the chassis is painted, or oxidized, the effects will be affected. It needs good clean connection to the ground of the equipment. Clean it before connecting. 
5. Examples - ground of RCA socket, ground of speaker binding post, ground of chassis, mains ground, and etc. 
6. Caution - do not touch the Audiobits Ground Box binding post after it is connected, just in case there are leakage or shorts. 

Recommendations - connect 1 Audiobits Ground Box to 1 equipment only. If you have more equipment, buy more Audiobits Ground Boxes!  

Before use:

1. Shake it to even out the materials as some components will settle during transportation.
2. Place it for at least 2 hours, or ideally overnight to let it settle before serious listening.
3. Place it on stable surface. Vibrations will affect the effects of the unit. It is VERY sensitive to vibrations. 
4. Burn in of 72 hours are needed to achieve maximum performance.

 Effects

1. Darker / quieter background.
2. Details retrieval
3. Deeper depth
4. Better soundstage
5. Lower noise floor
6. Better low and high frequency extension

Audiobits ground box needs to breath. It cannot be painted, waxed or oiled. Do it at your own cost! It uses soft wood for best effects. Hard wood is detrimental to the effectiveness. 

Take a look at the internals - it is very simple actually. 1 piece of 4N copper plate with high end copper binding posts. Unlike some, that only uses thin copper wires. The copper plate effects are much more prominent!

Special concoction of minerals are inserted. These natural stones are a secret formula of ours. It is formulated after many iterations and experiments. It is not filled fully so that it can breathe for better effectiveness. 

Audiobits Ground Box can be connected to an extension cord. The main purpose of the Audiobits Ground Box is to absorb ground noise and let all the noise electrons gets absorbed to the ground box. The worse the ground on the system, the better the effects of the ground box. 

Do note that the ground box is a virtual ground and MUST NOT be used to replace the ground/Earth line. 

The Audiobits Ground Box can be connected to the negative terminal of the speakers too. When speakers are working, back EMF will be generated by the speaker drivers and this is affecting the power amplifier, causing diffused sound and noise. The Audiobits Ground Box will help to absorb the high frequency back EMF and reduce the negative impact to the sound. Do note that each speaker requires 1 ground box - do not share!
