As you know, power is constantly increasing. Some users with the inclusion of powerful devices in the network often is a "landing", a significant decrease in the brightness of bulbs in the house. This is, primarily, is due to the fact that voltage is not always consistent with the stated 220 volts, and power devices – electric kettles, water heating systems, refrigerators, and is growing steadily. Also, some expensive equipment – computer technique, deep-well pumps, tele-video equipment, special medical equipment can be damaged by power surges or, say, lightning. To protect the expensive equipment and stabilize the output voltage in recent years have increasingly used a special device – the stabilizers. In fact, the voltage regulator is a controlled transformer turns ratio is changed by electronic circuit providing a voltage of 220 volts. Distinguish electromechanical step and ferroresonance stabilizers. Electromechanical regulators – the most reliable, as a rule, different compact, high accuracy output voltage retention.

There are one-and three-phase main field of application – private houses, small businesses and enterprises, polyclinics and medical centers. Electromechanical Regulators can function at low input voltage, which is also not a little important. Step – the most common, popular and affordable. Have a wide input voltage range, high accuracy output voltage and a high degree of protection. Finally, the third type, ferroresonance, they are distinguished by a high degree of protection, only the stabilizers of this type can withstand temperatures as low and high contrast, from -40 to 40 degrees and high humidity, they can be placed in cold areas. Unfortunately, they are not without drawbacks, and – a large, noisy work. Distinguish one-and three-phase stabilizer, and the choice should be paid firm and country producer. Chinese machines, filling the market recently, though cheap, but have a low margin of safety, they are frequent cases of failure, so profit by buying them is questionable.

It is worth pay attention to the company's long-established market for electrical equipment – Varcon, Polygon, Proton, Resanta and so on. Important and correct installation of the voltage regulator. It is best to use services of a professional electrician, but this condition will ensure the safety of the equipment and its proper connection. Thus, the specialist will need to be a necessary power. When you connect regulator must ensure that the section of cable is suitable for the current denomination and denomination machines that are set up regulator, exceed the value of current, otherwise the machine will "knock out" and adequate protection will not be achieved.

Do you know what country Audio and related technologies are most developed? "Of course, Japan!" – Many would exclaim when he saw something about technology. And they will be wrong! In fact, this old Britain. There are already several decades of living, create and live the large number of companies who are writing the history of the world of sound. Bowers & Wilkins, Tannoy, Dali, Wharfedale and dozens of other companies Albion, who are trendsetters in the high audio technology. It is good though, a leader in the video is Japan! In principle, it is even possible to comprehend.

Still, the music – it's not solid spetstehnologii, ultra-modern equipment and materials. It is also the soul. Production Company Cambridge Audio – this is what connects these two areas of modern equipment. Cambridge – a familiar word, is not it? Yes, it is in honor of the university town it was named. AV-receivers of this brand quite inexpensive, but very high quality. Even the brand itself admits it)) So, one of his models Cambridge audio without false modesty, calls "the most perfect-sounding receiver in the world." And believe me, so well respected and well-known brand will not lie! But not one soul sound vosproizvedesh, and even the soul understands this. However, AV-Receiver Cambridge Audio is not collected. And cutting-edge technologies and innovative materials and brilliant ideas they have not less than competitors – not even a step behind.

And in some ways, as it is found in major companies, and even ahead. Have all the features included all possible formats, all available media tested. But there is one such attractive funktsiyka – Pure Analog – to disable all the rest. Now if you want to remember the violent youth, phonograph records, cassette, nobody and nothing can stop you or hinder. I hope you did not mystery than good 'toroidal transformer with low external magnetic flux "- unlike me. And you know what he was better than other options such construction. Perhaps someone tell me? However, this is how I see it better – trade Brand would not just bragging. Cambridge Audio has also written to their specifications: 5.1, 6.1, 7.1, Dolby Digital Plus, HIGH-DEFINITION MULTIMEDIA INTERFACE and many other interesting characters. True, they already understand.
