microphones with an impedance of 600 ohm, equipped with
a 6.3 mm mono Jack connector on an unbalanced line.

When using a USB flash drive with a capacity greater than 4
GB, the complete reading of the content is not guaranteed.
Use pendrive that is not excessively large.
•
The PHONO input is intended for the connection of tradi -
tional analog turntables with a signal output at pickup level,
therefore without RIAA preamplification: the connection of
already preamplified turntables involves a highly distorted
reproduction and at an excessive volume, potentially har -
mful for the amplifier as much as for the connected spea -
kers. Pre-amplified turntables can still be connected to the
Aux input, with optimal acoustic results.
•
The AUX and DVD inputs are electrically identical: their dif -
ferent nomenclature only allows them to be easily distingui -
shed when using the amplifier.
•
Pay particular attention to respecting the polarity of the
loudspeakers, which must be consistent with each other:
the connection of a pair of loudspeakers with inverted po -
larity does not in itself constitute a situation of electrical or
functional risk, but significantly worsens the performance of
the reproduction, attenuating the low tones and distorting
the acoustic image, nullifying the stereo effect
•
It is possible to connect several speakers to each of the
relative pairs of terminals on the rear panel, as long as they
are interconnected with a configuration (in series or in pa -
rallel) that guarantees a total impedance of 8 ohms: since
the power required by the amplifier is proportional to the
number of speakers connected, it is advisable to connect
only one 8 ohm speaker to each output.
•
Avoid connecting speakers with excessive musical power,
as the output signal may be attenuated and distorted even
at low volume: this condition also produces inappropriate
overheating.
• To connect the speakers, push the lever located below each
access, then insert a strip of stripped cable approximately
2-3 cm into the hole above, finally release the lever and
check the correct fastening of the inserted cables
•
To connect to the analog sources input, use normal stereo
cables equipped with RCA connectors at the ends, trying to
