Avantone CLA-400 Amplifier
The flagship of the line, the Avantone Pro CLA-400 is a high-output, high-resolution Class A/B studio reference amplifier. Housed in a substantial 3U rackmount chassis, it pairs a massive toroidal transformer linear power supply with premium Japanese components. Unlike its smaller siblings, the CLA-400 implements a classic bipolar transistor design, delivering a robust, authoritative bottom end alongside an open and transparent frequency response.
Generating over 360W per channel into an 8-ohm load (testing up to a powerful 400W), this amplifier is specifically designed to drive large, demanding passive studio monitors that require massive amounts of headroom and serious dynamic range.
Despite its monolithic power output, the CLA-400 is entirely convection-cooled. By eliminating fan noise, the amplifier runs silent. It can be installed directly in the control room right alongside your monitors without impacting critical listening. It is engineered to handle harsh studio conditions easily, running continuously at one-third power without thermal fault.
Key Features:
- Monolithic Reference Power: Delivers 360W per channel into 8 ohms (400W tested) to effortlessly drive large passive monitors.
- Bipolar Transistor Architecture: Engineered specifically to provide a deeper, more robust low-end response.
- Classic Analog VU Meters: Generous, vintage-style VU meters offer precise, real-time visual monitoring.
- Silent Operation: Convection-cooled design removes loud fan noise from your control room environment.
