Never connect the amplifier to AC mains if the local voltage is
higher than that indicated on the rear panel!
The mains fuses are situated in the fuse-holder which is integral with
the IEC mains socket. The correct value of mains fuses is indicated on the
rear panel and in the technical specifications at the end of this manual.
Always replace fuses with new ones of the same type and value !

OPERATION
Warning! Switch on the
Unico Secondo
only after all the input and
output connections (including loudspeaker 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.
Best results will be obtained after approximately 10 minutes from
switch-on.
If you need to make adjustments thereafter to the source or the
outputs, always remember to turn the volume down to zero before doing so.
When switching on the
Unico Secondo
for the first time, we
recommend you check that the sound image is correct by playing a piece of
music that you are familiar with. If there is any doubt it will be best to
double check all the connections before proceeding.

FUNCTION OF THE LEDs
The
Unico Secondo
has two LEDs which provide the user with important
information about the operating condition of the amplifier; let name
LED1
the led near the input selector knob and
LED2 the one near the volume.
LED1 and LED2 on:
indicates normal operation
LED1 and LED2 blinking (fast):
indicates automatic start-up phase (approx 30 seconds)
LED1 and LED2 blinking (slow):
indicates intervention of the thermic protection device. Amplifier is
shut-down.
When the internal temperature has returned to normal the amplifier will
switch on automatically and repeat the initial start-up phase.
