Isolation transformer for HiFi system

Let's start by saying that an isolation transformer is essential if you use high efficiency and sensitivity speakers and amplifiers with high power and dynamics in your HiFi system.

It is therefore essential to "isolate" yourself from your home network as the various appliances, TV, PC, lights etc. they create interference that is reproduced by your system.

Clearly all this does not necessarily mean spending thousands of euros, but only studying in detail, based on the absorption power of your amplifiers and electronic accessories, the size of the transformer to be inserted at the head of your system.

Attention, isolating your network does not mean filtering it, it only means interposing an independent secondary level that does not reflect the various interferences from foreign devices and correctly shielding the two circuits.

AudioLai uses toroidal isolation transformers of different sizes depending on the type of absorption of the complete system, from 600VA to 1500VA.

The importance of isolating the network is well known to all those who use drivers with very high sensitivities, usually above 90db, sometimes just turning on a nearby light bulb can generate interference that can be heard even by those with inexperienced ears.

In addition to the isolation transformer it is essential to also use good power cables, the cable that carries power to the amplifier must be well shielded and if there is more than one they must be well spaced or intertwined.
