Thank you for purchasing the Constellation Audio Virgo preamplifier. And prepare for a
musical experience far beyond your expectations.
The Virgo employs essentially the same revolutionary circuitry pioneered in our Altair
preamp. Like the Altair, it’s designed for simple operation. However, as with Altair, the
unique design demands that certain aspects of setup and operation are necessarily a bit
different from those of typical stereo preamps. By reading this manual before you operate
the Virgo, you assure that you get maximum performance from the preamp.
