Sound reaches a certain level of fever after having gone through frequent replacement, pay attention to mix voice and wire the school after the development step by step, the vast majority of fans will eventually go from the source of the sound system is working to improve the quality of the road, which is the root cause - electricity. For ordinary people, spending lots of money charges vigorously playing audio, the sound quality improved a little bit of it so dispensable, it seems quite worthwhile. But it is different for enthusiasts to enhance the sound quality is their only pursuit, so in their ears, so little changes like "reborn" in general. How sound can not live without electricity. Electricity, although invisible, must not touch the stuff, but as an objective existence of matter, it is also true that the existence of contamination. Most of the sound using AC power, China's electricity is 220V, 50Hz, if you look with an oscilloscope, under normal circumstances should be very smooth sine wave, but in fact you often see with a lot of the waveform burr, and is not an ideal sine wave, which is pollution. As the saying goes, "mud, but not infected," but to really easier said than done. Now the environment is very complex electrical, industrial electricity and power consumption can not completely separate, so the noise power in more and more clutter, such as start and stop the motor, welding machines, hand drill, hair dryer, electric saws, planer, lightning, and this will lead to clutter and noise power, and ultimately will affect the Hi-Fi, AV equipment, audio-visual effects. Enthusiasts in the spare replacement, and alignment with other work, which makes pure power will put some on the agenda.

G & W TW-07D power filter is a combination of clean power products, many of the previous essence, 03D 05D shows the voltage grading touch switch medical, 06D and 08D of the most high-end studio-grade fine filter circuit, with the latest technology - - to the DC circuit. Its plain appearance, the blue paint from the 1mm steel plate shell, very strong; panel on the side with the power switch, reset switch and the correct phase / ground right light, the other end has eight outlets, which 4 white is the "product" type wildcard socket, the other four black is the national standard outlet. These socket component monomers are imported products, regardless of the shape of the plug, are plug and smooth, reliable contact. More practical in the internal circuit, eight sockets are divided into two groups, the panel marked "with filter" on the border within six sockets can be purified to provide current through the filter, the other two outside the border White Universal socket is unfiltered treatment, for those less demanding on power quality using common household appliances. The purification filter has a maximum operating voltage of AC270V, the maximum operating current of 15A (peak current of 20A), with a load power of 3300W. Reset switch with automatic overload protection circuit, when the load exceeds the sum of the filter can withstand the maximum power, or an external voltage is too high resulting overload, reset switch will automatically pop up the power cut off, then you need to overload troubleshooting , and then press the reset switch on the red button to restore power.

The study found that AC power is now the city is interspersed with a considerable portion of the DC component, the instrument displays up to a certain amount of DC current in series with the grid on the grid the pollution can be imagined. DC transformer magnetic saturation can lead to increased performance so greatly reduced. Experience tells us that the transformer humming noise and power amplifier in series with the DC output is the culprit, 07D birth is the best solution.

As the saying goes: a temporary solution before a permanent cure! If you have already started to enter the ranks of the pursuit of sound enthusiasts, I suggest you work on the purifying power line before replacement with the play, perhaps less than the older generation take many detours Oh!


For audio technology from the Qing Yi Lun Co., Ltd. G & W brand enthusiasts are already very familiar with nature. G & W is based on the initial research and development-based Hi-Fi amplifier, with a deep skill designer Mr. Wu Gang, have launched a variety of amplifiers, including the merge, before and after class, headphone amplifiers, and Pure Class A amplifier, tube amplifier, and so many type, are excellent sound performance won the esteem of enthusiasts. As this world are focusing on every brand-name power amplifier design as part of the performance, G & W is also in development process gradually realized the importance of power, so strengthen their own power amplifier design at the same time, they also began AC purifier R & D work, and has launched a TW-02MKII, TW-03D, TW-05D, TW-06D, TW-08D power a variety of different grades of purification products, connected with the power purifier, the effect on the sound system improvement has also been recognized enthusiasts.


TW-08D G & W is currently the most advanced, but the effect is the best power cleaner, but the price relative to the ordinary working-class fans, but still seems a little high. But we from G & W has always been the product can be found in them? And willing hissing about Yan Ren   numerous posthumous track  jump  geometrid Suo   Yan hundred trick tip more Post Chan raised basket Hwan thorn hilly ┳ curse Mei men read broom  kitchen Cang Ye  bad quarrel glanced Crest pro-plutonium benches Luo W-07D power purifier to be reflected. G & W TW-07D power supply before cleaning the filter with a variety of power purification products, the essence of many, for example, TW-03D shows the voltage, TW-05D medical grade anti-touch switches and the most upscale TW-08D in the fine filter circuit etc., and also added a new technology - to the DC circuit, can be quite comprehensive, and prices TW-07D cheaper than TW-08D more than can be said that any enthusiast can easily afford.


Now let us take a closer look at this tasting G & W TW-07D power purifier. Its plain appearance, the color of the paint from the 1mm steel plate shell, very strong; thick aluminum panel with power switch and voltage on the instruction sheet (with the use of advanced light warm retro round table header pointer), back board, it has a power cord socket and reset switch. Power cleaner at the top of the fuselage near the location of the panel with a correct phase / ground right light, the rear is a total of eight power outlets, four of which white is the "product" type wildcard socket, the other four Black is the national standard outlet. These socket component monomers are imported products, regardless of the shape of the plug, are plug and smooth, reliable contact. In the internal circuit, eight sockets are divided into two groups, the panel marked "with filter" on the border within six sockets can provide purified by filtering the current, the other two outer border white-purpose socket then, without filtering, for those less demanding on power quality using common household appliances.
The purification filter has a maximum operating voltage of AC270V, the maximum operating current of 15A (peak current of 20A), with a load power of 3300W. Reset switch with automatic overload protection circuit, when the load exceeds the sum of the filter can withstand the maximum power, or an external voltage is too high resulting overload, reset switch will automatically pop up the power cut off, then you need to overload troubleshooting , and then press the reset switch on the red button to restore power.

As the manufacturer has taken measures to prevent demolition, it can not be G & W TW-07D of the case open to find out. But back on the past seen a G & W power each purifier product internal structure, may be inferred that this TW-07D will remain the core component of the inductor and the RC low-pass filter consisting of components, and to ensure good performance, or will use high quality components, such as German WIMA polypropylene capacitors and Japan FDK brand cards such as inductors, resistors are high precision metal film 5 ring products, which are already introduced in each of a G & W common on the power clean used.

Be noted that, to get the power to achieve good results purifier, it must be plugged into the correct zero line, phase line (commonly known as FireWire) and ground the outlet; If there is no ground wire (many families in the modified line installed process, construction workers often find it troublesome, lazy and do not install the ground, because the role of ground in most of the time really is not obvious, people feel optional), clean the filter effect will be greatly reduced, so be sure to ensure proper installation of the ground. The ground is a good way to judge is well documented in the manual, users can simply step by step operation.

Theoretically TW-07D can effectively filter out AC line noise and interference, to improve the sound system of sound field width and depth, reducing background noise, sound system, make up the background sound is more quiet, transparent sound more clearly; also enhance the knot strength and position as the accuracy, increase the bass contour sense of sound enthusiasts is one of the necessary equipment; be used for video equipment, the same image can be effectively enhanced color saturation and sharpness, reduced TV in the noise, make the image clearer, more realistic colors.

The actual situation then? In fact the more advanced equipment, a part of any change in response to the more sensitive to agents just sent a set of "esoteric" for the advanced equipment to audition, including AZ-1 digital amplifier, UZ-1 universal player and SZ-1 SACD player, etc., use them to verify the effect of TW-07D is better. The speaker is connected with the still very familiar already heard the B & W Matrix 803.

Start audition, the first signal source and amplifier are inserted into the socket with a filter function, the sound immediately, there were significant changes, the biggest advantage of audio and video become more stable, and can say without the slightest sense of drift instability, The mellow sound sense has also increased, a larger volume can be never too noisy to enjoying the whole, the sound becomes steady throughout the many, some high frequency is relatively little appears to inhibit the flu. Based on past use of the power purifier experience, know that each machine is not necessarily the best use of filtering will listen, the more front-end or usually more sensitive to the power equipment (such as source or tube amp), improvement is more the front.

So then the amplifier into the socket with no filter, just continue to use the filter to the signal source, and then, after listening to one, feel the sound performance is not only calm, and the details of which still retain a clear reproduction of the recording, mixing traces of having deliberately to look or feel clearly visible, open air feeling has not changed, but the space is clearly more convincing picture, audio and video lines clear and bright, the separation of instruments maintain the same degree level. In addition the volume could have been bigger, but also with the fidelity of the volume increase.

These are relatively minor improvements, and improved low-frequency range is relatively large flexibility of the music section with the same volume, the drum skin hit hard when the crisp feeling was not affected, but the big hit after the low-frequency elastic increase, more live percussion interesting, sense of rhythm is more prominent. Another is the frequency of the analytical, the human voice in addition to the original vocal chest resonance, the sound of singing in some of the technology transfer can hear some more first cavity resonance performance of three-dimensional sound levels are significantly and progress.

G & W TW-07D power purification effect is quite good, but ultimately, I want to say is: the effect of power purifier performance significantly or not, and the quality of AC itself has a relationship. If the AC power grid in the presence of contamination is more serious, then purifying the effect of the fairly obvious, like water through a filter, it becomes crystal clear after the same; but the quality is better if the AC itself, then the purification effect may not less obvious, is used to filter tap water filter, before and after filtration surface not much different from the need for users to savor, after a long period of subtle, the once and then remove the cleaner, it may find The effect turned out to be so strong.

As we all know, with the rapid development of digital technology, digital appliances and more widely, giving the work and lives of great convenience, but also to the grid disturbance caused by more serious. Daily digital interference of these appliances will not have any adverse effects, but the sound, the sound quality is so stiff. Blurring the background, status is unclear, a more sensitive high-level sound, so sound quality is greatly reduced, using the power filter to improve the sound quality is an indisputable fact. But sometimes used improperly, there will be slower, weakened the shortcomings, so the power supply filter circuit design and materials must be rigorous and reasonable. Filter design has taken into consideration the factors, but also pieces of the filter to minimize the impact on sound quality, to enhance the sound quality.
