I have some experience designing and building conventional (Class A & AB) audio amplifiers, both with ICs and with discretes, but I'm new to Class D. I'm thinking of experimenting with one of those pre-assembled medium power modules from China. Here's an example:
Putting other considerations aside for the moment, what I want to ask others with more experience is this: Most of the modules are
2-channel types. If I were to use only one channel and ground the input of the unused channel, does leaving the output open pose any potential problem? Bridging the two channels is not an option since each channel is already bridged.
