Сетевой фильтр Taga Harmony PC-9000DC (черный)

PC-DC power conditioner combines 4 functions in one device: power noise filtering; DC component blocking; linear power supply for USB ports; and surge and overload protection (for all powered outputs and USB ports).

The electricity network in our homes or workplaces is exposed to different interferences for instance electromagnetic interference (EMI) generated by appliances connected to the same network (refrigerators, air conditioners, computers etc.).
These interferences are not only produced inside your house or office but by all appliances in your building or even outside it and can differ on the time of day or week when the traffic on the electrical network changes.
All these interferences which we call noises can get into your AC power and interfere with your system.

Most DC-powered electronic devices use simple, low-cost external power adapters with switch-mode power supplies.
Such adapters operate at high switching frequencies to supply power, which may cause various electrical noises getting to the connected devices, and even inject these noises into your electricity network affecting other equipment.
Such noises dramatically deteriorate the sound performance and efficiency of audio-video devices.
The solution is to use a high-quality linear power supply, such as the one in the PC-DC conditioners.
The PC-DC linear power supply offers a very significant and immediate upgrade to the sound performance of your DC-powered devices.
