Other connections on the Virgo
5. Power inputs
These inputs connect to the power outputs of the Virgo’s separate power supply. The Virgo includes special
spiral-wrapped, gold-plated copper cables designed for aerospace use. Each cable is rated to handle 30 amps.
Each of these jacks mates with a matching jack on the power supply. Be sure to connect the Analog power jack
on the preamp to the Analog power jack on the power supply, and the Control power jack on the preamp to the
Control power jack on the power supply.
Before connecting these cables, switch off the Virgo’s power supply and disconnect it from the AC power.
Failing to do this can damage the Virgo or its power supply.
