General Info

Actions Technology's home audio series mainly offers dual-mode Bluetooth 5.4 solutions, characterized by high audio quality, low latency, and multi-connection capabilities, primarily applied in wireless home theaters, soundbar TV speakers, and A/V Receivers.

The ATS2835P(L) supports dual-mode coexistence of classic Bluetooth reception and 2.4G proprietary protocol forwarding, supporting multi-connections (up to 1TX+4RX+4.0 channel wireless transmission and reception), with latency as low as 16ms (based on LC3+HR). Compared to classic Bluetooth (SBC), the 2.4G proprietary protocol (LC3/LC3+) ensures better sound quality with a THD+N of over 90dB (based on LC3+HR). The ATS2833P features a smaller package and a more streamlined BOM, making it a more cost-effective choice for RX. The ATS2853 only supports classic Bluetooth but can utilize the TWS mechanism to achieve a highly integrated and cost-effective soundbar+subwoofer product.

The main chips currently promoted include: ATS2835P(L), ATS2833P(L), and ATS2853, among others.
