The Avantone Pro CLA-400 Studio Reference Amplifier is designed to provide professional-grade power and clarity for passive studio monitors. Delivering an impressive 360 watts per channel at 8 ohms, this amplifier is built to handle high-output demands with precision and reliability. With a convection-cooled chassis eliminating fan noise, it ensures a silent and distraction-free studio environment. Engineered for studios requiring serious dynamic range, the CLA-400 maintains low distortion and offers a transparent, open sound that enhances critical listening and mixing accuracy.

High-Performance Class AB Amplification
Built with a classic Class AB design, the CLA-400 delivers the warmth and detail expected from a professional studio amplifier. Unlike modern Class D alternatives, this amplifier provides a more natural and dynamic audio response, making it an excellent choice for audio engineers and producers who demand high-fidelity sound reproduction. The amplifier can sustain operation at one-third power without overheating or thermal fault, ensuring reliability in demanding studio sessions.

Convection-Cooled for Silent Operation
One of the standout features of the CLA-400 is its convection-cooled design, which eliminates the need for a fan. This ensures completely silent operation, making it ideal for studio control rooms where noise levels must be minimized. The rugged 3U rackmount chassis efficiently dissipates heat, allowing extended usage without compromising performance. This feature makes it perfect for professional mixing and mastering environments where even the slightest noise interference can be disruptive.

Built with Premium Components for Maximum Durability
Avantone Pro has meticulously crafted the CLA-400 using high-grade Japanese components, ensuring durability and consistent performance. The amplifier’s construction includes a robust toroidal transformer linear power supply, which enhances power efficiency and reduces unwanted noise or electrical interference. This level of craftsmanship ensures long-term reliability, making the CLA-400 a solid investment for professional audio studios.

Versatile Compatibility for Studio Setups
The CLA-400 is designed to work with a wide range of passive studio monitors, making it a flexible choice for different studio environments. Whether you’re using medium or large speakers, this amplifier provides the necessary power and headroom for dynamic sound reproduction. The front panel features classic analog VU meters, adding a traditional studio aesthetic while allowing precise monitoring of output levels.

Precision Audio Performance with Low Distortion
With a frequency response of 20Hz–20kHz and a damping factor of 250 at 100Hz, the CLA-400 delivers tight, controlled bass response and pristine high-frequency accuracy. Its low total harmonic distortion (THD) of less than 0.1% ensures clean and accurate sound reproduction, making it an excellent choice for critical mixing applications. Additionally, the signal-to-noise ratio (SNR) of over 103dB ensures ultra-low noise performance, preserving the clarity of your audio signals.

Rackmount Ready with Professional Studio Features
Housed in a standard 3U rackmount chassis, the CLA-400 integrates seamlessly into any professional studio setup. Measuring 19 inches in width, 18 inches in depth, and 5.25 inches in height, it fits into standard studio racks for easy installation. At 49 pounds, it provides a solid and sturdy build that ensures stability. The amplifier also includes balanced and unbalanced inputs, catering to a variety of studio configurations.
