CLASS-D POWER AMPLIFIER
This amplifier relies on convectional cooling only. In normal
situations, overheating will not occur due to the class-D amplifier
topology. Since there are no cooling fans in the amplifier, make
sure the convectional cooling system can work properly. The unit
can be built in a 19 inch rack system, but it is forbidden to block
the ventilation holes provided. Therefore, it is absolutely necessary
to allow at least one free rack space or 44 mm above and beneath
the amplifier. Make sure the ambient temperature is between 0
and 35°C. Operating the unit beyond its normal limits may cause
overheating. Power amplifiers are hard workers, and their behaviour
is similar to human beings. In extreme conditions, human beings are
not able to perform efficiently. This also applies to amplifiers. It is
generally a bad idea to mount multiple heat generating units such
as amplifiers in the same rack. If necessary, use a forced ventilation
system in your mounting rack.
The mains fuse is located inside the unit. When the fuse is broken,
replace it with a fuse of the same current and voltage rating:
T 3.15 A L / 250 V. For qualified personnel only!
This unit has NOT been designed for use in mobile applications,
such as: mobile discobars and DJ setups, mobile PA systems, live
bands, audio rental systems, …
Note: Before using the amplifier for the first time, check the
impedance of your 100 volt speaker lines using the Apart IMPMET:
temporarily disconnect the speaker line from the amplifier and
measure the speaker line. Impedance @ 100 volt must be 83.3
ohms or more. This value corresponds to 120 watts @ 100 volt.
