APart CHAMP-3D is a 3 channel, fully programmable digital amplifier. It has the same advantages as
the other models in the CHAMP series : it is convection cooled, thus eliminating the need for a fan. As
a result of this, the amplifier is totally quiet, but also there is no risk of amplifier failure (in case a fan
gets clogged up by grease or dust).
CHAMP-3D is ideal for medium to mid-sized applications with a total power up to 2100 Watts. The
amplifier has high end Hypex® amplifier components inside. They are the absolute top in components
and otherwise used by high-end hifi brands. Hypex® components have a very high damping factor,
which eliminates unwanted cone movement. This ensures a very pure sound.
A toroïdal transformer with oversized capacitors guarantees a dynamic sound. There is an independent
transformer for the subwoofer channel and another for the left/right channel. A balanced analogue
internal signal flow is a further guarantee for a perfect quality sound.
CHAMP-3D has a build in DSP with a 4-band fully parametric equalizer. It allows the user to adapt the
crossover and the the delay/time alignment of the loudspeakers. The DSP also has automatic loudness
(defeatable) and a built-in compressor function that increases musical density. An incorporated limiter
– leveler allows the installer to set a maximum music level that cannot be overruled by the user. This
function is very handy for use in bars or cafés: it forces the user to stay within maximum sound
regulations and it protects the speakers. A subsonic filter eliminates harmful frequencies and protects
both the amplifier and the loudspeakers.
Different user levels make it possible to deny or give users access as required. The first level is 'fully
locked' mode: the user has no access to functionality of the unit and can only switch the unit on and
rd
off. In the second level the user can change the volume (up to a pre-set maximum) and the 3 level
gives full access to all the DSP parameters.
The built-in speaker wizard makes it possible an APart loudspeaker out of a list, and the amplifier will
automatically apply the correct settings for the speaker chosen. The list has all APart loudspeakers that
work with CHAMP-3D, and can be updated via RS-232. Updates of the list are posted on the APart
website A correct installation of loudspeakers through the speaker wizard
guarantees a fully protected system: No clipping thanks to overload protection, the preset maximum
level can not be exceeded.
Just like the speaker wizard, all firmware can be updated via RS232. CHAMP-3D has also a very low
power consumption, only 1.5 Watts in standby mode. The amplifier is only two rack units high and
takes very little build-in space. A wired external volume control button is optionally available.
