I need your help. Need to plug in Mohu or any other OTA to Denon 1610 to get surrond sound. From the research I have done, this is not possible without buying an ATSC convertor ? Is that correct ? Any other options
Correct. AVRs do not have TV tuners installed on them to include the 1610. Rather you must plug the OTA cable into the TV and then connect the optical audio output from the TV to the 1610 for surround sound audio from the HD channels.
