I have more than one source device. How should I connect the devices? Directly to the TV or better to the Canton Smart product?

Connect all sources directly to the Canton Smart product to avoid issues such as faulty image rendering. TV internal sources (tuner, apps) can output a multichannel signal via ARC/eARC. External sources connected directly to the TV can only output a stereo signal. Direct connection to the Canton Smart device guarantees the best audio signal.
