CLASS-D POWER AMPLIFIER
!!!IMPORTANT!!!
This amplifier relies on convectional and active cooling. In normal
situations, overheating will not occur. 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 will result in excessive
internal temperature. 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 an additional 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: 5
AT/250V. 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 …
Use it in fixed installations only.
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 ohms or more. This
value corresponds to 120 watts @ 100 volt.
