One way to reduce amplifier power consumption is to reduce the bias current flowing through the output devices. This has two effects: it reduces the idle dissipation (good) but increases the crossover distortion (bad).
By applying the THX patented circuit, it is possible to virtually eliminate the crossover distortion while retaining the benefits of lower power consumption.
For portable devices with AAA, this means unlocking a Class-A experience with long battery life and small form factor.
For desktop devices with AAA, this means cool operation and minimal carbon footprint.
