The Class D Wondom AA-AB32255 amplifier module is based on a TAS5756 chip from Texas Instruments (TI). This allows it to deliver a power of 2x30W at 4 Ohm and this with a high efficiency of 90% and a precise sound reproduction.

In addition, this chip integrates a digital-to-analog (DAC) converter and supports I2S input signals while offering support for sampling rates up to 24bit 192kHz in PCM. The intelligent design of this module allows it to greatly limit output noise, to have a high SNR of 102dB and a THD+N of 0.06%. An analog output of the module also offers the possibility to use only its DAC function without amplification

The module can be powered by both an AC adapter via 5.5/2.5mm DC jack, a linear power supply or by using a Wondom battery module (these elements are sold separately). It can also be combined with a volume control knob and an ON/OFF switch (sold separately).
