The Current feedback amplification topology and powerful power supply of the A-48S amplifier provides a large reserve and stable output in pure Class A. For a load with an impedance of 8 ohms, 50 watts are available, and halving the load impedance doubles the output power. With a short-term drop in load impedance to 1 ohm, the amplifier is capable of delivering a power of 400 watts.
