No-compromise build quality A classically designed Class AB amplifier, Avantone builds the CLA-400 the old-school way, with no-compromise components in a rugged 3U convection-cooled chassis. The CLA-400 can be used with any passive studio monitors that require serious dynamic range. Avantone exercised meticulous care to create an amplifier in the traditional studio style, with generous VU meters, high-grade Japanese components, and a beefy toroidal transformer linear power supply. No fan noise — ideal for control room installation Meticulously designed into a standard 3U rackmount chassis, this amp can generate over 360 watts per channel into an 8-ohm load, making it perfect for medium-to-large speakers in a studio control room environment. The CLA-400 is convection cooled, so there’s no fan noise — which makes it even better suited for control room installation.
