The Power
Supply
The SXH2 has an internal power supply. These designs are
invariably more sophisticated than those featuring external plug-
in power packs. Special attention must be paid to shielding,
supply transformer design, capacitance and earthing.
Perreaux has specially developed a fully shielded internal
toroidal power supply. A total of 22000µF of smoothing
capacitance and low pass RC filters are employed to provide a
“rock-solid”, super low ripple, linear DC power supply.
