1.3 Warning Notices
1.3.1 Location
Install the amplier in a well-ventilated location where it will not
be exposed to high temperature or humidity. Do not install the
amplier in a location that is exposed to direct sun rays, or near
hot appliances or radiators. Excessive heat can adversely affect the
cabinet and internal components. Installation of the amplier in a
damp or dusty environment may result in malfunction or accident.
1.3.2 Precautions Regarding Installation
Placing and using the amplier for long periods of time on heat
generating sources will affect its performance. Avoid placing the
amplier on heat generating sources. Install this amplier as far as
possible from tuners and TV sets. An amplier installed in close
proximity of such equipment may experience noise or generic
performance degradation.
WARNING: To prevent re or electric shock:
▶
The ventilation openings must not be impeded by any item
such as newspapers, tablecloths, curtains etc; keep a distance
of at least 50 cm from the front and rear ventilation openings
of the amplier.
▶
Do not expose this amplier to rain or moisture.
▶
This equipment must not be exposed to dripping or splashing
liquids: objects lled with liquids, such as vases, must not be
placed on the amplier.
1.4 Safety Rules
▶
This device must be powered exclusively by earth connected
mains sockets in electrical networks compliant to the IEC 364
or similar rules.
!
▶
It is absolutely necessary to verify this fundamental
requirement of safety and, in case of doubt, require an
accurate check by qualied personnel.
▶
The manufacturer cannot be held responsible for damages
caused to persons, things or data due to an improper or
missing ground connection.
▶
Before powering this amplier, verify that the correct voltage
rating is being used.
▶
Verify that your mains connection is capable of satisfying the
power ratings of the device.
▶
Do not spill water or other liquids into or on the amplier.
▶
Do not use this amplier if the electrical power cord is frayed
or broken.
▶
Do not remove the cover (except for the topmost user
installable accessory panel). Failing to do so will expose you
to potentially dangerous voltage.
▶
No naked ame sources such as lighted candles should be
placed on the amplier.
▶
Provide a sectioning breaker between the mains connections
and the amplier. Suggested device is 16A/250VAC, C or D
curve, 10KA.
▶
Contact the authorized service center for ordinary and
extraordinary maintenance.
▶
The power cord type is LAPP CABLE OLFLEX191 3G6 /
Bahoing SJT 3x16AWG or I-sheng SGIS 3G1,5mmq.
1.5 Speaker Damage
Powersoft Class D ampliers are among the most powerful
professional ampliers available and are capable of producing
much more power than many loudspeakers can handle. It is the
user’s responsibility to use speakers suitable to the amplier and
to use them in a sensible way that will not cause damage.
Powersoft will not be held responsible for damaged speakers.
Consult the speaker manufacturer for power handling
recommendations.
Even if you reduce the gain using the amplier’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 tone 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 ampliers of this power
range for more headroom (cleaner sound) rather than for
increased volume.
1.6 Speaker Output Shock Hazard
A Class D amplier is capable of producing hazardous output
voltages. To avoid electrical shock, do not touch any exposed
speaker wiring while the amplier is operating.
