Avantone Pro CLA-400 Stereo Power Amp

Power your passive studio monitors with the CLA-400, an 800-watt studio reference amp meant to bring your studio the most pristine power available.

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 took 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 360 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 large passive monitors that demand the highest amounts of power. 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.

The CLA-400 Studio Reference Amplifier is perfect for studio environments requiring high power output with no fan noise. Under testing, it delivers a powerful 400 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.

"AVANTONE CLA-400 POWER AMP REVIEW"

Overall: 4.5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
This amplifier is big, heavy and very well built. I can't think of one amplifier anywhere near this caliber. The sound is very impressive it presents with a warm and detailed sound the soundstage is impressive i am impressed with the vocal reproduction and localization and separation of instruments. Excellent for 1200 bucks. I have previously owned krell products so i know what i am talking about. The power meters don't work at low power output avantone needs to address this issue.I recommended this amplifier to the discerning ear.
