About the KA M 650

The Karan Acoustics KA M 650 is a high-end mono power amplifier from the Master Collection POWERa series. It features a fully balanced, sliding bias class-A design with a true differential mono chassis. The amplifier delivers 2,100 watts into 8 ohms, 3,600 watts into 4 ohms, and 6,000 watts into 2 ohms, with a peak power output of 2,400 watts at 8 ohms. It uses premium components such as Sanken bipolar output devices, Audyn and proprietary Karan capacitors, Vishay and Roederstein resistors, and Cardas Audio wiring. The amplifier includes an advanced mains line conditioner to reduce DC-related noise from the power supply, which can be switched on or off during operation. It has one balanced XLR and one unbalanced RCA input, with an input impedance of 30kΩ and sensitivity of 2.0V RMS for maximum output. Frequency response is flat from 20Hz to 20kHz ±0dB, extending to DC-300kHz at -3dB. Distortion is very low at 0.03% THD/IMD, and signal-to-noise ratio exceeds 120dB unweighted. The amplifier weighs 105 kg and measures 50.4 × 29.2 × 60.3 cm. It is finished in silver aluminum and comes with a 5-year parts and labor warranty. The price is approximately per pair (two mono amplifiers).
