DC volume control stages are integrated into the input stages so that no coupling capacitors are required and a low offset voltage is still maintained The minimum supply voltage also remains low The BTL principle offers the following advantages Lower peak value of the supply current The frequency of the ripple on the supply voltage is twice the signal frequency Consequently a reduced power supply...
