S.M.S.L A300 Bluetooth Power Amplifier for Stereo/Mono Hi-Fi Speakers, 2.1ch, 2.0ch, 1ch, BTL, 330W Class D Audio Digital Amplifier

Equipped with a new Infineon amplifier IC! Exceptional energy efficiency delivers high sound quality and superior audio performance. The A300 can be used in stereo (165W+165W) mode, or in BTL mode, it becomes a high-power mono amplifier with an even higher 330W, allowing you to create the optimal system for your speaker pairing. Normally, a 2.0-channel Hi-Fi sound system is created by pairing it with a pair of passive speakers. However, when ultra-low bass is required, switch the A300 to high-pass mode (you must also switch to stereo mode). This cuts the bass in the stereo section through the internal high-pass circuit. Connect a subwoofer via the SW terminal to create a 2.1-channel sound system with ample low-frequency volume! Supports Bluetooth 5.0 input. Enjoy the best music wirelessly anywhere! SMSL patented SDB effect, bass/treble compensation, and remote control operation.
