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.
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 Auricle 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.
