Maintenance
The Virgo requires no regular maintenance.
If the preamplifier’s surface becomes dusty, simply wipe it off with a soft dry cloth. Do not spray cleaners on
the surface.
To clean fingerprints from the surface of the preamplifier, spray a small amount of mild window cleaner such
as Windex onto a soft dry cloth, then use the cloth to remove the fingerprints. Do not spray the cleaner directly
onto the preamplifier.
Troubleshooting
Preamplifier will not turn on
1. Check to see if the front blue LED on the power supply is illuminated. If it is not, try the following steps in
order. After you perform each step, touch the Power button on the front of the unit and wait a few seconds to
see if the blue LED is illuminated. If any one of the steps restores the power (i.e., allows the Power button to
turn the unit on), there is no need to continue to the next steps.
A. Check power cable connections between the wall and the Virgo's power supply. Push the wall plug and
the connector at the power supply in firmly.
B. Check power cables between Virgo and power supply. DO NOT pull out these cables while the power
supply is on.
C. Make sure the master power switch on the rear of the power supply is turned on.
D. If the Virgo is plugged into an AC line conditioner, make sure the line conditioner is turned on.
F. Flip the master power switch off and on again. This will reset the Virgo's internal circuit breaker.
G. Check the circuit breaker for the AC circuit that the Virgo is plugged into. If the breaker is tripped, flip it
back on. If it will not turn on, there is likely a short circuit somewhere in the lines or in a device connected
to this AC circuit. Check the power cords for your components to make sure none have been damaged.
H. If none of these conditions restores power, it is possible one of the Virgo's internal fuses is blown. Do
not attempt to change the fuse yourself—the Virgo requires the use of special high-voltage fuses that are
not commonly available. Contact your Constellation Audio dealer for service.
Preamplifier is on but no sound is produced
1. Make sure the front LED on the power supply is glowing blue, indicating that the preamp is powered up and
not in warm-up mode.
2. If the LED is lit and the Standby screen is visible on the LCD panel, press the Power button under the front
LCD or on the remote to restore sound.
3. If the LED is lit and the volume numbers on the LCD panel are flashing, hit the Mute button on the front
panel or on the remote to restore sound.
4. If neither the Mute or the Power button restores the sound, try the following steps in order. If any one of the
steps restores the sound, there is no need to continue to the next steps.
A. Check you are on the correct input. Cycle through available inputs using the front touchscreen controls,
or select the desired input using the remote.
B. Check that the source component is on and playing back—i.e., if it is a CD player, make sure that the
CD is playing and not in pause mode.
D. Check the connections between the Virgo and your amp, and between the Virgo and the audio source
device. If a cable is disconnected, reconnect it. If this does not restore sound, try substituting a different
set of cables in order to make sure the original set was functioning properly.
E. Check the connection between your amp and the speaker. Make sure the speaker cable has not come
loose. If it has, turn the power off on your amp, then re-install the cable.
