Due Volte Power Amplifier Owner’s Manual

The Due Volte Power Amplifier is equipped with fuses for protection
against excessive AC current draw; however, since no protection
circuitry or system can completely protect a product from every
electrical hazard, certain precautions should be observed. In the event
of severe voltage hazards such as lightning or when the
amplifier will not be used for extended periods of time, the amplifier
should be unplugged from the AC mains to avoid potential damage to
the internal circuitry. All other audio/video system components should
also be disconnected from AC mains power as hazardous voltages can
easily travel throughout an interconnected system.
RISK OF ELECTRICAL SHOCK!
WARNING: Do not attempt to access the interior of the Due Volte
Power Amplifier by removing the top or bottom cover. Doing so will
void your warranty and could expose you to dangerous, potentially lethal
electrical voltages.

Installation, Use & Care
Locate the amplifier as close as possible to its final installation point.
Allow access to the rear panel for making connections.
Typical installations allow the amplifier to be rigidly coupled to a support
structure or floor via optional spiked coupling supports that are available
separately. In carpeted installations, these supports provide excellent
anchoring from the amplifier chassis to the
rigid floor or sub-floor below. If there is concern about damage to the
structure or floor’s finish, a coin can be placed beneath each spiked
coupling support. In installations where the resonant properties of the
supporting structure are poor or unknown, the amplifier chassis can be
loosely coupled to the supporting structure via the supplied compliant
isolation interface pads. This will help to attenuate the transfer of vibration
or resonant energy from the support structure to the amplifier chassis.
• Do not expose the amplifier to rain, moisture, or excessively damp
conditions.

Installation, Use & Care
• The Due Volte Power Amplifier must not be modified in any way, other
than according to official service bulletins from Arte Forma Audio.
Otherwise, the factory warranty will be immediately voided.
• The Due Volte Power Amplifier can be operated at a nominal 100 ~ 120
volts AC. The amplifier must be configured for the correct AC input voltage
before operation or serious damage will result.
• Be sure the amplifier is unplugged from the AC mains wall plug (front panel
indicator light OFF) before connecting or disconnecting any loudspeaker or
interconnect cables.
• When operating Due Volte Power Amplifier , a properly grounded AC
receptacle should be used. A potential shock hazard may result if the supplied
3-wire, grounded AC cable ground terminal is defeated or lifted or the unit is
connected to a 2-wire ungrounded AC outlet.
• The output terminals or loudspeaker cables should never be shorted to each
other or to any chassis surface. Shorting of the outputs may result in damage
to the output section of the amplifier.
