A:AnswerThere is no device that I know of that would reduce the power from the speaker lines, though you could make it yourself, but why do that when it has a ear phone output in the front and you could hook up more that one set of ear phone on it.
A:AnswerThat's not the way to make the connection. You will use the RCA audio out behind the TV to connect to the audio in (also RCA) at the back of this unit. You need a stereo RCA -RCA cable.
A:AnswerIt probably has Bluetooth 3.0. I don't have any problem with Bluetooth connection. It printed aptX label next to Bluetooth logo on the box. Google aptX to see its advance. You will need to have aptX built-in on your device when connecting to this receiver to take advance of this technology.
A:AnswerThis receiver will only power one set of speakers at a time. 8 ohm speakers. The question is whether the Niles will cause problems as it switches as opposed to using the speaker selectors on the remote.
A:AnswerNO, the speakers do not work when headphones are plugged in. This is so that you can listen to music without disturbing anyone else. Nice feature when playing RAP music so no else has to listen to that horrible noise.
