Avantone CLA-400 – Sporting a hefty wattage and traditional studio aesthetics, the CLA400 is Avantone’s most powerful standalone power amplifier to date.

800 WATTS of Reference-Grade Power

The Avantone Pro CLA-400 Studio Reference Amplifier is a dynamic, high output, high resolution, full-range system built the old school way; a classically designed Class A/B amplifier. Avantone Pro have taken particular care to create an amplifier in the traditional studio style, with generous VU meters, high quality Japanese components and a serious toroidal transformer linear power supply. The CLA-400 implements a classic bipolar transistor design for robust bottom end.

In a standard 3U rack mount chassis, this amplifier can generate over 400 watts per channel into an 8 ohm load, making it perfect for medium to large speakers in a studio environment. The CLA-400 not only uses no-compromise components, but is also convection cooled – no fan noise, so it can be used in the same room as the monitors.

The CLA-400 was designed to be paired with the CLA-10 studio monitors, contact us for prices, but it can be used with just about any demanding speaker load. Very low distortion, steady performance under harsh conditions, and an open and transparent sound make this an obvious choice for discerning studios requiring serious dynamic range.

Zero Fan Noise

The CLA-400 Studio Reference Amplifier is designed to be used in a studio environment requiring high power output with no fan noise. Under testing, it delivers a powerful 208 watts into 8 ohms and can run at one third power without thermal fault. The CLA-400 has zero fan noise, as it’s convection cooled — which makes it perfectly suited for control room installation.
