3. CONNECTION TO THE MAINS
The
Unico Primo
is set at the factory to the appropriate mains
voltage of the country it will be shipped to.
IMPORTANT!
The voltage setting may not be changed.
Never connect the Unico Primo to AC mains if the local voltage
doesn’t match the value indicated on the rear panel!
The mains fuse is located in the fuse-holder integrated in the IEC
mains socket.
IMPORTANT!
Always replace fuses with new ones of the same
type and value.
4. OPERATION
SWITCHING-ON AND WARM-UP
WARNING!
Switch on the Unico Primo only after all the
connections have been made and checked.
Before switching on, ensure that the volume control is at zero (fully
anti-clockwise), and allow it to remain in that position until the
initial automatic start-up phase is complete.
Just after switching on Unico Primo automatically starts a warm-up
phase, the LEDs placed on the front panel near the input selection
and volume knobs blink. In this status output stages are disabled,
however with an input source a weak signal can be heard through the
loudspeakers.
The working temperature for the tubes is reached less than 30
seconds after switching on but best results will be obtained after
approximately 10 minutes from switch-on.
