Before you install the Virgo
Unpacking
Take care when you remove the Virgo from its packaging. Because of its machined aluminum top chassis, it is
heavier than the average preamp. Have an extra person nearby to help if you need it. You may wish to use
gloves to protect your fingers.
Power supply setup
The Virgo's separate power supply (bottom component in the picture above) must be connected to the Virgo
main chassis (top component in the picture above) as shown above before you plug the unit into a wall. Make
sure the power switch on the power supply is in the off (O) position.
The supplied cables are spiral-wrapped, gold-plated copper designed for aerospace use, and can handle up to
30 amps. Only these cables should be used between the power supply and the Virgo.
Connect one of the supplied cables to the Analog power socket on the Virgo, then into the Analog power socket
on the power supply as shown above. Repeat with the Control power connection.
At this point you can plug the Virgo power supply into the wall socket. Leave the master power switch off until
you connect your other equipment to the Virgo.
DO NOT remove the power cables while the unit is powered on. If you do happen to accidently pull one of them
out, DO NOT plug it back in. Turn off the power supply using the hard switch on the rear panel, unplug the unit,
then replace the cable. Failure to power down the unit before replacing a power cable can result in substantial
damage to your Virgo.
If you will be using the Constellation Audio Centaur or Hercules amplifiers (or any other high-powered
amplifier), do not plug the Virgo into the same AC socket or into any other outlet connected on that circuit.
