Avantone Pro CLA400 Overview

Looking for a professional amplifier capable of powering medium to large studio monitors? Check out the Avantone Pro CLA-400 Studio Reference Amplifier, a dynamic, high-output, high-resolution full-range amplification system. Built in the "old school" way, the no-compromise design features high-quality Japanese components, generous VU meters, and a serious toroidal transformer linear power supply. The convection-cooled chassis provides fanless, silent operation, allowing the amplifier to be used in the same room as the monitors.

The CLA-400 boasts a frequency response of 20 Hz to 20 kHz (±0.5 dB) with a power output of 360W at 8 ohms and 540W at 4 ohms per channel. The amplifier can also be used in bridged mode, providing 760W into 8 ohms.
