A descent product.
Has ordered 3 of tis board.
But faced a humming issue from 2 of the board, which i am not sure is the issue of any other components.
But a descent product.
Also one thing to note is that, this is not 4.1, it's 2.1 ( 2 ic bridged for woofer and each for each satellite speaker ).
Dont connect 4 speakers of 4 ohms into it.
It will burn or reduce the life of board.
