This extra data translates to richer audio detail, greater dynamic range, and a more immersive soundscape.

Buying a brand-new 7.1 AV receiver can cost hundreds or thousands of dollars. A decoder kit allows DIY hobbyists to build their own custom multi-channel amplifier stack using cheap Class-D amplifier boards (like TPA3116 units) for a fraction of the price. 3. Precision True Surround Sound
