i can only see aux input is what it says in the manual not 3.5mm audio out?
You wrote that you have a Yaber Y30 projector. Have a look at post #2 in this thread. See in the first line where the word projector is underlined? That's a hyperlink. Click on it. It will open a link to a review of the Yaber Y30. I went online and spent time looking up details of the Yaber Y30 because you never put anything more useful than the product name in your OP.
Once the review of the Yaber Y30 is open, scroll down looking through the pictures. Find the one with a blue-coloured connector marked "PC-RGB". See in that same image the two connections to the left. One is marked "Audio-out". It is a 3.5mm jack audio out connector. This is where you would connect the Sonru transmitter.
If your Yaber Y30 is not the same as the Yaber Y30 in the review then there's not much anyone can do to help you until you post images of your own machine and a link to the user manual.
You see, the mainstream projector brands such as Optoma, Benq and Epson don't change their product design without changing the model number along with it. This means if anyone posts a review with pictures then what's seen in those pictures will match the model for all the examples sold. If the makers of your Yaber 30 decided to change the design, or you listed the wrong model name, then you should post pictures and a link to the manual.
If there's no audio out on your Yaber Y30 then you're stuffed. It won't matter which BT 5.0 transmitter you buy, if there's no "
give-me-audio-out-from-my-projector" socket to connect it to then you're not getting sound out of this projector.
Before you ask, the answer is No, you can't use the
audio-in or
AV-in socket if present. These are normally "
let-me-send-a-sound-signal-in-to-my-projector" sockets. Mainstream projector manufacturers don't make sockets where the function doesn't match the labelling. This means that if a socket is an output then the labelling includes the word "Out", and if it's an input then it includes "In", and if it was bi-directional, and controlled by changing some menu setting, then the label for that socket would read something like "audio-in/out". The signal connection sockets on bits of hardware are not clairvoyant; they won't change from an
In to an
Out simply because that's the connection you want today.
is there a way i can connect both projector soundbar and sonru using optical connector
For what benefit? For a simple stereo audio signal then Optical is no better or worse than analogue via the 3.5mm jack on the sound bar. They're the same quality.
If you manage to get sound out of the projector via a 3.5mm stereo audio jack then it will be analogue stereo. To connect that to the Optical input on the sound bar means converting stereo in analogue form as an electrical signal to stereo in digital form as light pulses. It's still the same information, the same base quality; just repackaged to suit an optical connection.
In simpler terms, you'll spend money on a box to convert analogue stereo to digital stereo via optical, for no improvement in quality, but now you'll even more cables and junk about to do what could have been done simpler and just the same quality with an audio cable with a 3.5mm jack on each end.
"
But optical can carry a 5.1 surround signal whereas analogue stereo can't, so isn't that better?"
Sure, optical is capable of a full 5.1 channel surround signal, but only when
all the following conditions are met:
- both the source device and the receiving device have optical connections (and they're connected by a working optical cable and the optical input is selected)
- the disc/game/film/TV programme carries a Dolby Digital of DTS 5.1 audio signal
- the source menu selections enable the output of a bitstream signal via Optical
- the receiving audio device has the speakers to play a 5.1 signal (A sound bar that is stereo only cannot make full use of a 5.1 signal because it doesn't have the correct speaker configuration)
- the menu settings on the audio receiving device do not defeat any ability to replay discrete 5.1 in either DD or DTS
When the sound bar is purely stereo -
as is the case with the bomaker tapio1 2.0 channel soundbar (the clue to stereo "2.0" is in the model description) - then stereo via Optical is all you'll get, and that will be the same quality as stereo via a 3.5mm jack. No difference.
When the source device - your projector in this case - only has 3.5mm analogue stereo out then that's the best you're going to get. Converting it to optical won't improve things.
The final word here; stereo via a 3.5mm-to-3.5mm jack cable will be
better than Bluetooth 5.0.
