CHAMP-3D 3-Channel Digital Power Amplifier

Producer: Apart

Digital CHAMP-3D is a 3-channel, fully programmable digital amplifier. With the same advantages as the other models in APart’s series of convection cooled amplifiers and much more: a built-in DSP, a fully parametric 4-band equalizer and RS-232 control of all essential functions. Genuine Hypex amplifier modules at the core of the unit for a superior sound quality. And a loudspeaker wizard for quick and easy set up with APart loudspeakers.

CHAMP-3D has the same advantages as the other models in APart's CHAMP series. 

The 3-channel amplifier is convection cooled, thus eliminating the need for a fan. The result is a totally quiet amplifier, but also there is no risk of an amplifier failure because the fan is clogged up by dust or grease.
