In June 2018, Avantone Pro released the CLA-10 studio monitors, which became the #1 selling passive studio monitor in the world. Now, Avantone has done the impossible and improved on an already great design with the CLA-10A. These high-grade studio monitors feature the same AV10MHF and AV10MLF drivers and cabinet construction as the CLA-10, but adds a Class A/B power amp section. You also get the 'Variable Tissue Paper Control' knob, which enables you to simulate the sound of the Vertical 'm' and horizontal Studio models of the monitors that inspired the CLA-10s.The CLA-10A uses a monolithic integrated circuit Class AB amplifier with wide voltage range and high current output capability. Operating in Parallel Mode with two devices ganged together to deliver higher output power into low impedance loads, allowing better thermal performance at high power. At low power, THD is a phenomenal 0.005%; at rated load it is 0.1%, yielding excellent performance at power compared to class D amps. The circuit uses a mixed bipolar MOS high voltage technology called BCDII 100/120 which avoids secondary breakdown phenomena. This technology handles high current output without unwieldy circuit complexity and external components, making it possible to deliver very high power in a reasonable package with the clean, smooth sound of a linear amplifier.The CLA-10A runs at +/-40 VDC, yielding a rock solid 200WRMS at 1kHz into 8 ohms. Rather than a switch mode power supply with the associated noise, the CLA-10A utilizes a linear power supply. The power supply uses a massive old school toroidal transformer for the classic performance of an AB amplifier. Many companies use SMPS and Class D for this type of system. Avantone decided to stay with classic technology in order to maintain the legacy sound that everybody associates with this design.
