The VTPH-2 features a
1
/
2
inch thick
anodized aluminum front panel
with three lights for monitoring the
operational readiness of the unit.
When the VTPH-2 is powered up,
the automute feature is engaged
until the unit is ready for operation.
The first indicator on the panel is
the Power LED, which indicates the
unit has been turned on. After a few
moments, the voltage LED gradu-
ally brightens, as the voltage to the
filaments slowly increases. When the
unit is ready to operate, the Output
LED illuminates and the automute
is disengaged, allowing signal to
be passed to the line stage/preamp.
This process generally takes just
more than a minute, but can take
considerably longer if the unit has
not been operated for a long period
of time. The output LED will flash
on and off during the 15 second
Moving Coil/Moving Magnet mode
change. This indicates that the unit
is muted for speaker protection.
