This ZK-MT21S amplifier board works fantastic! The bass is rich and powerful, and setting it up with 12V DC adapter was straightforward. The audio output is clear even at high volumes, totally worth the purchase.

이 Creall HT21 앰프 보드 정말 대박이에요! 소리 품질이 투명하고 설치도 아주 쉬웠어요. 블루투스 연결도 안정적이에요— 絕對 돈값 하는 제품이에요!

This CA 1215 converter board did repair my TV’s power problem. The operation guidance is a bit limited, but I found helpful tips online to get it set up correctly.
