Power Supply
The power supply was carefully engineered to provide clean and consistent currenttttan
important prerequisite for excellent audio. Built around a toroidal transformer, the power
supply generates a minimal electromagnetic eld with no hum or mechanical noise. The
output side is ltered by an RC circuit to extract noise and hums inherent in commercial AC
power.
All audio-related components are fed by two separate voltage regulators to minimize distur-
bance from other components.
An AC power cord is included for connection to the standard 3-prong IEC connector. The trans-
former, power cord and IEC connector are VDE, UL and CSA approved. The AC fuse is rated at
500 mA (230 V version) or 1 A (115 V version).
