I'm looking to replace my Samsung SIR-T451 OTA digital tuner. Would this unit function in the same method as the Samsung? That is being able to convert over the air broadcast signal and then send that signal via HDMI to my projector?
Sorry, I didn't want to get in the middle. Most small speakers, some with RCA connectors, will work when connected directly to a TV. This is normally a very flat panel plasma. On every TV I have every owned or used the "audio out" is a line level fixed output of the high impedance variety, not for the low impedance 4 to 16 ohm small wattage speakers.
IF I was asked the question I would have asked for the TV's model number, found its manual online and determined the properties of the "audio out" connectors. Then I would have suggested either passive or active (powered) speakers. After many years I have never used internal TV speakers.
The rear of your HW-150PVR also has RW audio connections. If I asked "can I connect my bookshelf speakers to them", would you say "yes"?
Your web site manual indicates the RW audio RCA jacks of the HW-150PVR connect to the TV or an amplifier. But it does say "optional" on top of the amplifier. So I guess I can live with that.
