« on: March 16, 2018, 08:45:30 am »

Wondering if anyone has tried this yet.. Tried to take two computers into a single USB-P DI box?

I have several and they work great...but I have no idea what you mean about trying to use two computers into a single USB-P DI box.  The USB-P provides a balanced line level stereo out from a single computer - it appears to the computer as an audio interface.  There's no way to use it with two computers.

Exactly how do you think you could do this?

2 computer audio sources on 1 stereo input, I guess.
Not a bad question.

Like 2 amplifier outputs on one speaker? Not sure what Al's got in mind here...

Oh Schnikees!    :-[  It is a bad question.

<lots of erroneous advice deleted>

You are right, Dave ...I'm going back down the rabbit hole, now.

You're onto something (maybe).  Set both computers to output in mono, then pick one channel  (tip or sleeve) off each PC to a TS->XLRF cable (1 for each PC) into the two inputs on the USB-P. 

Set the USB-P output switch to mono... Voila! (-excuse my French)  ;D

-Dennis

TS->XLRF example:  Hosa PXF110 - 10'

????

The XLR's are outputs.

The USB is the input.

I recently was doing RF for a corporate event. They had several apple laptops as playback. Each laptop had a backup, where both were going into a USB hub. They had a special cable adapter to take into the USB DI. This way, the backup goes through the same lines.

USB hubs don't work in that direction - they connect multiple devices to a single computer, not multiple computers sharing a single device.  I don't have any idea how it could possibly work the way you are describing it.

If using the same audio lines is the goal, the analog outputs of multiple Peavey boxes can be combined using a passive summing network as detailed here:  http://www.rane.com/note109.html

That is correct.
However, some people may not understand how USB hubs work and is why I don't see the OPs question as unreasonable.
Just because it's clear to some people doesn't mean it's clear to all.

And, no, it;s not like 2 amps to one speaker  :)

I don't know how you can get more than one computer into a USB hub, they don't even have the connectors for that.

This would be a better solution.

Al,

There are KVM switches that will take in multiple channels of display, audio, and control signals and allow you to toggle between them - sometimes automatically.

I think that this may have been more along the lines of what was being used, particularly for a corpy gig.
