AV questions hdmi to xlr?

[RiverDave]

So on my sign truck we currently have a lap top that outputs hdmi which goes to a video processor which outputs cat 5 to the screen.

My audio processor only has xlr inputs and outputs.

So I am looking to get something that will split the audio out of the hdmi and output xlr for audio and video to the video processor..

I can’t seem to find anything that does that?

Any ideas?

I doubt anyone makes an HDMI audio extractor with a balanced output. You’ll probably need to get one with stereo analog outputs and then run it through and unbalanced to balanced converter.

Tons of audio extractors on Amazon. The ART CleanBox Pro works good at converting to balanced.

What do you mean balanced to unbalanced etc?

What do you mean balanced to unbalanced etc?

XLR is a balanced audio connection, it uses 3 wires, is at a higher nominal voltage and is what all pro audio uses. Typically balanced audio is either XLR or a 1/4” jacks for audio connections.

Residential and car (unbalanced) audio you are used to only uses two wires, runs at a lower voltage and typically uses RCA cables or 3.5mm jacks for analog connections.

The audio extractors to pull audio from the HDMI out of your laptop are going to have an unbalanced output (either RCA or 3.5 jack). You could feed that directly into your XLR input on your mixer with an adapter, but the levels would be really low (among some other potential issues), that’s why you need to convert it.

So it looks like it’s two conversions to get to where I need to be

Yeah, I linked to the products you’ll need in my first post.

One to go from HDMI to analog. Another to get it to XLR.

I have one of these in my Moho to pull audio from HDMI and spit out to the old analog Bose surround sound system. You'd just need this and a 3.5mm stereo to XLR adapter like:

Hdmi into this... HDMI to SDI

SDI output into this ... Embedded audio SDI to XLR

Just use the headphone jack out of the laptop for your audio, convert that to XLR.

If the laptop is running windows you can select where you want the audio to be sent (Bluetooth, headphone jack, USB audio device, HDMI)

This looks like it'll work as well... just need a couple male XLR turnarounds... Terranex HDMI to SDI

That'd work but you'll have all sorts of sync issues, audio not matching video at the truck video processor. Worth a try though to see if it is acceptable for your use...

Didn't realize the screen processor imparted that kind of delay

Probably 4 to 5 frames at least. Definitely noticeable.

I did a Google search and this site came up. These guys seem to know about this.

I had to look up what an XLR cable is. Seems like something @Dan Lorenze would know about...

A lot of the new laptops do not have a 3.5mm out. If @RiverDave has one then a cleanbox would be all he would need to properly convert to a balanced signal.

If I want to use existing equipment to run my new smart TV, what do I do with the red, white, and yellow wires coming out of the back of my VCR?

so ~200ms.... yeah it could be borderline depending on the content.

Usually 100ms is the max detectable by most people
