Avantone Pro has unveiled their CLA-10A, an active studio monitor version based on their CLA-10 passive monitor and CLA-200 amplifier.
Avantone Pro’s CLA-10A active monitoring system shares the same 35mm AV10-MHF high frequency silk dome-based tweeter and custom-designed 180mm AV10-MLF low-frequency driver — based on the famed Yamaha NS-10 paper cone construction. Being an active design, each pair of CLA-10A monitors contains matching A/B power amplifiers. The CLA-10A includes a rear-mounted VTPC (Variable Tissue Paper Control) knob that allows users to simulate the vertical M model to the horizontal Studio version, enabling each user to choose the tweeter brightness that best suits their particular needs. The CLA-10A uses a linear power supply to deliver 200W of Class A/B output.
Avantone Pro’s CLA-10A employs a monolithic integrated circuit Class A/B amplifier with voltage range and current-capable output. Operating in Parallel Mode — with two devices ganged together to deliver higher output power into low impedance loads — claims to provide better thermal load performance at high power. At low power, THD (Total Harmonic Distortion) is 0.005%; at rated load it is 0.1%, yielding solid 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 by handling high-current output without circuit complexity and external components. Consequently, this makes it possible to deliver power in a reasonable package with the clean, smooth sound of a linear amplifier.

Actually, the system itself is being run at +/-40 VDC, yielding 200W RMS at 1kHz into 8 ohms. Obviously, rather than use an SMPS (Switch Mode Power Supply) with the associated noise that is inherent in this technology, Avantone Pro opted to take a traditional design route, remaining with a linear power supply. So the power supply itself uses a toroidal transformer to create the classic performance of an A/B amplifier. Although many companies choose to use an SMPS and Class D for this kind of system, Avantone Pro decided to stay with classic technology to maintain the legacy sound that everybody associates with this design.
Avantone Pro’s CLA-10A will be available in late-March/early-April 2019 for $999 per pair.
