Can someone help me with a cool query about connecting a projector to a sound systems

Looking to buy a projector and sound bar. Looking at the specs and don’t know if I’ll be able to connect them up easily/optimally.

Projector outputs:

Soundbar inputs:

Looks like I’ll def be able to hook it up with some combo of mini jack to RCA or whatever, but I don’t know what a digital coaxial cable or digital optical cable are or whether they will plug into this projector.

Can any of you super cool tech dudes help a friend during the pandemic?


I thought projectors didn’t do sound, just the video from a source, e.g. your laptop.

you were wrong mate

Surely you’d plug whatever you’re putting through the projector into the soundbar, rather than the projector itself?

For example, if you’re projecting a ps4, plug the hdmi into the projector and the audio cable into the soundbar, so that the ps4 outputs video to the projector and audio to the soundbar

Oh right yeah. So mini jack to RCA wil have to do then I guess

Need to plug the USB-C through the coaxial snog release valve, then use a CMYK port set to 1118 to synchronise the wattage (about 4/kg) past the firewall.




What is it you are projecting?

Films and tv

Sorry, I meant more what are you projecting from, laptop, sky box etc?


Ah right. Yeah, mini jack to rca will probably do you then

A position of privilege!!!


You’re fine with the “Good” solution as long as you’re not an intolerable tech nerd. Almost all digital film screenings I have ever rigged have used the former. And yes, sound goes directly from source to sound plank, not via projector (some projectors do play a little sound but no-one uses that as it’s shit).
