CHAMP-3D is a fully programmable three-channel digital amplifier. Like the rest of the CHAMP series amplifiers, it features convection cooling, with no need to use a fan. As a result, the amplifier is completely silent, and the possibility of the amplifier failing due to a fan blockage caused by dust or grease is completely eliminated.

CHAMP-3D is ideal for medium-sized applications requiring a power output of up to 2100 W. It features Hypex® components, the highest quality on the market and used in high-end hi-fi equipment. These components have a very low damping factor, which eliminates unwanted movement of the speaker cones. This ensures a very pure sound. The presence of a toroidal transformer and oversized capacitors guarantees an extremely dynamic sound. It features independent transformers for the subwoofer channel and for the left / right channels. The internal balanced signal flow offers an even greater guarantee of perfect quality sound.

The amplifier also features an internal DSP with a fully parametric four-band equalizer. This allows the user to adapt the crossover and the delay / time alignment of the speakers. This DSP also offers automatic Loudness (switchable) and a built-in compression function, as well as a limiter that allows the user to set a maximum level that cannot be exceeded. This function is very useful in bars or cafes, as it forces the user to stay within the levels required by regulations and protects the speakers. A subsonic filter eliminates unwanted frequencies and protects both the amplifier and the speakers.

Various user levels provide or deny access to different users, as required. The first level is a ‘fully locked’ mode: the user does not have access to any functionality of the equipment, and can only turn it on or off. At the second level, the user can change the volume (up to a preset maximum level), while the third level provides full access to all DSP parameters.

A built-in speaker wizard makes it possible that, if APart speakers are used, the amplifier applies the correct settings for each speaker model. These are defined in an internal list that includes all APart speakers that work with the CHAMP-3D; this list can be updated via RS-232. Updates to this list are available on the APart website. Likewise, the firmware can also be updated through RS-232.

CHAMP-3D features a very low power consumption, only 1.5 W in ‘standby’ mode. It only takes up 2 units in a standard rack. As an option, a wired external volume control is available.
