3. CONNECTION TO THE MAINS
The Unico 90 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 by the user.
Never connect the Unico 90 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 and inside the amplifier.
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 90 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 90 automatically starts a warm-up
phase, the LEDs placed on the front panel between the input
selection and volume knobs blink. In this status output stages are
disabled.
The working temperature for the tubes is reached less than 40
seconds after switching on but best results will be obtained after
approximately 10 minutes from switch-on.
