As a part of APart's revolutionary series of convection cooled power amplifiers, Champ-4 is an
amplifier without cooling fans. Its four discrete AB-class amplifiers deliver high quality musical sound,
high dynamics, and high reliability - all in a one-unit 19” enclosure.

Power amplifiers have to operate in demanding circumstances. Places where the air is full of dust,
nicotine or grease. Because power generates heat, power amplifiers typically have fans to keep their
electronic circuits cool.
nicotine or grease. Because power generates heat, power amplifiers typically have fans to keep their
electronic circuits cool.
Unfortunately, these cooling fans are a major headache in the use of high-power amplifiers. They tend
to be noisy, and if -or rather, when- the fan breaks down because of dust collection, the amplifier
overheats and ultimately fails
.
A fanless amplifier seems the logical thing, but -until now-, the idea never seemed to work for high
quality amps with high output power. Thus, installers stick to fan-cooled models and get out of bed to
replace a fried amplifier ….

No fan
Unique design
Especially for the CHAMP-series, APart introduces unique, custom-designed side mount heat sinks. In
combination with a self-supporting low resonance frame, they make it possible to create a discrete
power amplifier without a noisy and dust-collecting fan inside the enclosure.

This means: less maintenance, no annual fan or dust filter exchange procedure, no more amplifier
cleanout, and no more unwanted noise from cooling fans. Because of this, Champ-4 can rely on
convection cooling only !
