Area 5.1
Built around a torroidal transformer, the power supply allows for a
minimal electromagnetic field with no hum or mechanical noise.
The power supply's output side is filtered by an RC circuit to
extract noise and hums caused by your power service. 30.000 µf
capacitors smooth out the positive and negative half waves.
The phantom power is derived from a separate winding in the
transformer, a precise current regulator delivers a clean phantom
power of 48 volts. High quality 0.1% / 6,81 kOhm resistors ensure
the pristine quality of the phantom power supply.
The supply voltage can be set to 230 V/50 Hz or 115 V/60 Hz.
Check your country's power requirements for the appropriate
setting. An AC power cord is included to feed the IEC-spec, 3-
prong connector. Transformer, AC cord and IEC-receptacle are
VDE, UL and CSA approved.
Chassis ground and AC ground can be physically disconnected
by the “Ground Lift” switch (GND LIFT). This helps to eliminate
hums.
