TinySine's TSA7499B module is Class D amplifier that deliver no less than 2x100W at 6Ω. It is also combined with an AudioB Plus module to offer Bluetooth reception supporting aptX, for more convenient use. This amplifier is based on a TI TDA7498 chip. The TSA7499B can be powered by any 14-39V DC power supply. In addition, in order to protect the heating components from possible deterioration, a fan makes it possible to cool the assembly. This is activated only above 65°C in order to reduce the noise emitted.

TSA4799B amplifier is designed specifically for DIY enthusiasts. Thus, you will have on this module a line/bluetooth input and an audio input in the form of JST connectors. Therefore, you can integrate this amplifier in a box and for example associate an external switch as well as an RCA or 3.5mm jack connector. To simply adjust the volume, you can also add a volume controller to this amplifier, like those in the TinySine TSA1000 series.
