What bluetooth gadget do I need?

[audi321]

Long story short I have a projector at one side of the room and some speakers at the other. Both cannot be connected by a wire without a real big hassle.

Is there anything what I can buy which will allow me to connect the projector to these speakers?

Projector has Bluetooth audio output. Speakers are just cable inputs.

Thanks all for any help!

Assuming your speakers are powered amplified speakers (or they have an adjacent amplifier) then something like this should work:



Be aware that you may have some audio delay using bluetooth, your projector may have a setting to adjust this.

What speakers are they?
Are they active or connected to a amp?

Just speakers. No amp or anything powered but I could always put a spare amp onto them easily enough.

So ‘Bluetooth audio receiver’ is the gadget I need. Thanks guys!

I have a Prozor Bluetooth DAC which seems OK to me and only cost about £20, it feeds an old HiFi amp.

If you don’t have any amplification then something like this

I've got a similar one of those, same manufacturer - "NobSound". Used in the shed/gym. It's tiny, but gives surprisingly good sound.

Does anyone know if there’s such a thing like this but with optical in rather than bluetooth?

I use one of these Prozor SPDIF/Toslink DACs between the optical out of a PC and a HifI amp in my office.
Works well enough for me and cost under £20. Seems to have a tidy BurrBrown chip in mine, but I've had it some years.
I power it with a usb phone charger.

I also have a Bluetooth version I bought later.

Cheers but I’m looking for something tiny with the amp built in (like that bluetooth one). Something with speaker outputs.

Plenty of mini amps about, but the only amps with optical and dac built in seem to be high end headphone amps, or I think Cambridge did some big amps with DAC and USB built in?

It's an odd corner of the market, I wanted a cheap optical DAC to investigate earth hum which I was blaming on my PC, turned out to be the amp going senile. A lot of DACs are loads of money for the same chip in a nice box.

Putting 'optical amplifier' into amazon search throws thigs like this:
https://www.amazon.co.uk/Sabaj-Bluetooth-Optical-D...

But I have no experience of those, and at £80, I can get the little box I have and a reasonable separate amp.

OP be careful.


There is a thread on here about synching headphones to TV - and there is a Bluetooth special protocol. ( not your vanilla Bluetooth ) needed to keep the audio in sync with the video.

Will see if I can find it - but worth a search

Lots on the interweb about adjusting lip sync for various devices.

You can get the effect of being in a really big concert hall. :-)

I have this as linked below for making a modern tv talk to a non bluetooth surround sound home cinema system. Very happy with it.

Theres cheaper out there but Beware as there was sound lag with a couple of 20-30 pound type ones and as you can imagine thats super annoying with pictures and sound not matching.
