The output stages of the Matrix Audio MA-1 power amplifier are made on discrete elements and operate in class A/B. To reduce the output impedance, ten high-power ONSEMI transistors operate in parallel in each channel to create a push-pull amplification circuit operating in a state of high bias current. At a load with a nominal resistance of 8 ohms, the amplifier provides an output power of 250 watts per channel and 450 watts per channel at a load of 4 ohms.
