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 personnel.
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.
!

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 power-handling
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 low-frequency 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.
