## Description

HiFi class D stereo amplifier module for power audio projects, offers 2x420W on two channels with TDA8954TH and works with 2-8 Ohm speakers. It is powered by dual AC 24-30V, has a generous radiator for efficient dissipation and screw terminals for quick connection. Recommended with preamplifier for volume and tone control.
Class D amplifier module, XH-M252 with TDA8954TH, two channels of 420W each, which supports speakers with impedance between 2 and 8 ohms.
It is recommended to use a 24VAC double loop power supply and a 300W or larger ring transformer.
It uses two surface-mounted TDA8954TH integrated circuits, with a large enough radiator to cope with the power dissipated by these integrated circuits. The board has screw terminals for connection and uses a series of 1000uF, 50V capacitors.
It is also recommended to use a tone pre-amplifier filter to be able to control the volume and the tones.
