FX-Audio showed a new budget stereo amplifier FX 502E-L

While there is a new quarantine in China due to the coronavirus epidemic, new technology is presented on video presentations. On the alibaba platform, the Chinese manufacturer of affordable audio equipment FX-Audio showed its new products on video. We will focus on the FX 502E-L stereo amplifier.

The 2022 FX 502E-L is a deep upgrade of the 2020 FX-502SPRO. The 502SPRO was simple and built on a TPA3250 class D chip and had a maximum output of about 70W. Both devices are essentially budget desktop amplifiers for compact audio systems.
