Clearaudio BASIC - Handbuch (Seite 6)

- Notice –
Be aware of the right polarity of the external power supply by changing the phase of the mains
plug. If no phase testing equipment is available, try to find the right position of the power chord
by alternately turning the plug and listening. You will hear the difference!
Phonostages are devices designed to provide a very high level of amplification. This is necessary
because the electrical signal generated by a phono cartridge is extremely low (usually less than
one-thousandth of a volt). The job of the phonostage is therefore to accurately equalise the phono
signal and boost it to line level (measured in volts).
However, phonostages are by nature extremely sensitive, which leads to the potential problem
that high-frequency interference may also be amplified to a point at which it becomes noticeable.
Unfortunately it is not possible to completely protect the sensitive phonostage circuitry from this
interference without degrading its high fidelity performance. Therefore care must be taken to
position the phonostage away from sources of high frequency interference such as mobile phones,
modems and powerline communication systems (PLC) in which data is sent over the mains power
network.
