My husband wanted to wanted to buy a small sound mixer to improve audio sound at home. I felt like it isn’t necessary because we only have small house and we don’t even have an entertainment room. However, when he tried to install the sound boxes for the TV I was amazed that I felt like I was inside a movie house. According to him, a sound mixer would do more to improve its sound. I think we’ll have to look for first-rate numark mixers and see if its what we need for our home.
