3E AUDIO Amplifier Board Stereo Class D Balanced TPA3255 2x 225W 4 Ohm
This stereo amplifier module integrates a TPA3255 amplifier chip, allowing it to develop a consequent power of 2x 225W under 4Ω (1% THD+N) while taking advantage of the high efficiency inherent to its Class D architecture. The careful design of the module allows it to display very good measurements, such as a background noise of 85µVrms or a dynamic range of 111dBA.

Stereo Class D TPA3255 2x 225W 4 Ohm
This stereo amplifier module integrates a TPA3255 amplifier chip, allowing it to develop a consequent power of 2x 225W under 4Ω (1% THD+N) while taking advantage of the high efficiency inherent to its Class D architecture. The careful design of the module allows it to display very good measurements, such as a background noise of 85µVrms or a dynamic range of 111dBA.
The two inputs, on 3 pin 2.54mm connectors, can operate balanced or unbalanced, via a jumper adjustment. An auxiliary power supply output is also available, delivering 12V 0.2A, allowing to supply a preamplifier module.
The module may only be powered via a power supply input. Never connect both power inputs simultaneously.
