One can also use the RCA jacks in the back of the converter box to hook it up to a surround sound or home theater system as well. the box doesn't require manual selection of audio out, the ones i use automatically enable the A/V out soon as a connection is made (Zenith and Digitalstream).
The above diagram is also good for hooking to a DVD Recorder,
DVR, or other audio/video device (
HDTV monitor,
LCD computer monitor, etc).
