OPERATION
Turn the "Volume" control fully counterclockwise.
Mute is automatically engaged when switching on the unit.
Allow the preamplifier to warm up for a minute before you un-mute the unit; failure to wait
can cause a transient to be sent through your power amplifier that might cause damage to
your loudspeakers.
PLEASE READ THE SECTION ON FRONT PANEL CONTROLS BEFORE USING THE PREAMPLIFIER.
As with all high fidelity products, the sound characteristic of the VAC changes somewhat
as it warms up. Best sound will be achieved after about 15 minutes of operation.
Any time that the Phi Preamplifier has not been used for a few weeks the sound may be
different. This is also normal for high resolution audio equipment. Optimum sound should
return after a few hours of operation, preferably with an audio signal.
Note that although your VAC System has been run for 48 hours at the factory, it will
continue to "break in" for approximately 150 hours. Also be aware that many components
display the need for a new break in period after being transported in unheated cargo
aircraft.
FUSES
The fuse is located behind in a tray above the AC power connector; the fuse carrier
contains the fuse being used, as well as a spare.
For 220 or 240 volt operation, please use a 1.0 ampere fuse. For 100 or 120 volt operation,
the fuse should be 2.0 amperes.
Voltage conversions must be accomplished at the factory or via the importer for your
country. Please consult the factory for more information.
