A:AnswerThis does not have HDMI or optical audio, so it wouldn't work directly from your PS4.
However, you can connect your PS4 to your TV via HDMI and if your TV has audio out via RCA you can connect it back to this receiver. (Look for audio out on your TV)
A:AnswerThis receiver can receive Bluetooth input, but for output it only connects to wired speakers. It cannot send signal to Bluetooth/wireless speakers.
A:AnswerI don't know what Sonos is. Our receiver is connected to a CD exchanger and also to the computer to play music through it.
Don't know if this helps.
A:AnswerThe raw line out is not controlled. It's the signal that usually goes to a tape deck for recording. If your amp has volume and equalizer controls then you could run the line out to it via the RCA plugs. If it doesn't I think what you are looking for is a preamp.
A:AnswerHi there, thanks for your inquiry! The STR-DH190 Bluetooth stereo receiver has an audio analog output for an active speaker or soundbar connection. You can connect a soundbar that supports RCA audio cable connection. Thanks! -Sam
A:AnswerYes it does. I have 8 ohm speaker now and its not the best for it. My volume is always at 25 or higher to get any sound. This is an entry level amp and not ideal for a traditional hi-fi setup. Its just enough to get music for blue tooth connection and FM stereo. I would pay extra to get the right amp if looking for a hi-fi setup and not this one.
