The global power supply works anywhere in the world and offers PFC ( Power
Factor Correction).
It is a switching power supply easily deals with a very high variation in the AC
mains voltage: it can drop by up to 20% below its nominal level (e.g. to 180VAC
instead of 230VAC ) without any loss of the amplifiers rated output power. A
regulated power supply also presents some other sonic advantages, such as
better cone control and the same fast response as a linear power supply.
