(2) The powerful BTL power amplifier is composed
of the op amp NE5532 and two LM3886 in-phase and inverting amplifiers. It is a pure BTL bridge amplifier that can easily output
more than 200W of undistorted power and can be used in dance halls, theater amplification and other occasions. This circuit can still
maintain natural and smooth sound quality when playing at low volume . The BTL power amplifier circuit is shown in Figure 10-12. Each channel has a circuit board with independent rectification, filtering and driving
circuits. The dimensions of the two radiators are 1×40×50×1OO(mm)6
