Warning Notices
Location
Install the amplifier in a well-ventilated location where it will not be exposed to high temperature or
humidity.
Do not install the amplifier in a location that is exposed to direct rays of the sun, or near to hot appliances
or radiators. Excessive heat can adversely affect the cabinet and internal components. Installation of the
amplifier in a damp or dusty environment may result in malfunction or accident.
Precautions regarding installation
Placing and using the amplifier for long periods on heat-generation sources will affect performances. Avoid
placing the amplifier on heat-generating sources. Install this amplifier as far as possible from tuners and TV
sets. An amplifier installed in close proximity to such equipment may cause noise or degradation of the
picture.
WARNING: To prevent fire or electric shock, do not expose this equipment to rain or moisture.
“Apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases,
shall be placed on the apparatus.”

Safety rules
This device must be powered exclusively by earth connected mains sockets in electrical networks
compliant to the IEC 364 or similar rules.
Is absolutely necessary to verify this fundamental requirement of safety and, in case of doubt, require an
accurate check by a qualified personal.
The constructor cannot be considered responsible for eventual damages caused to persons, things or data
for the missing of accurate earth link.
Before powering this device verify that the amplifier is supplied with the correct voltage rating.
Verify that your mains connection is capable to satisfy the power ratings of the device.
Do not spill water or other liquids into or on the unit.
Do not use this unit if the electrical power cord is frayed or broken.
Do not remove the cover. Removing the cover will expose you to potentially dangerous voltage.
No naked flame sources such like lighted candles should be placed on the amplifier.
Contact the authorized center for ordinary and extraordinary maintenance.
Speaker damage
The DIGAM series amplifiers are among the most powerful professional amplifiers available and are
capable of producing much more power than many loudspeakers can handle. It is the user’s responsibility
to use suitable speakers with the amplifier and to use them in a sensible way that will not cause damage.
Powersoft will not be responsible for damaged speakers. Consult the speaker manufacturer for powerhandling recommendations.
Even if you reduce the gain using the amplifier’s front panel attenuation controls, it is still possible to reach
full output power if the input signal level is high enough.
A single high-power crescendo can damage high-frequency drivers almost instantaneously, while lowfrequency drivers can usually withstand very high, continuous power levels for a few seconds before they
fail. Reduce power immediately if you hear any speaker “bottoming out” - harsh pops or cracking distortion
that indicate that the speaker voice coil or diaphragm is striking the magnet assembly.
Powersoft recommends that you use amplifiers of this power range for more headroom (cleaner sound)
rather than for increased volume.
Speaker output shock hazard
A DIGAM amplifier is capable of producing hazardous output voltages. To avoid electrical shock, do not
touch any exposed speaker wiring while the amplifier is operating. This manual contains important
information on operating your DIGAM amplifier correctly and safety. Please read it carefully before
operating your amplifier. If you have any questions, contact your Powersoft dealer.
