can you have 2 channels to stream

I use a USB mixer/interface to live stream a mic and guitar. I use 1 channel for each on the USB mixer. In OBS I use the mic filters, but the filters seem to also affect the guitar. Is there a way I can stream the filtered vocals and have a clean guitar channel for live streams??
 
Using a Behringer X222usb mixer. The vocal mic is on one channel and the guitar on another. How do you keep those 2 channels separate on OBS for live streaming? The signal leaves the mixer as 2 channels but only one channel on OBS, so the obs filters seem to affect both guitar and vocal?

ah the X2222usb you mean
its have only a 2 channel stereo output
its only for record the master chanel

for multi-track recording in the PC you need better a other mixer or you only use the mixer as preamp for mic


you can also buy a second cheap interface and use the aux channel and get the signal from your guitar into the pc i know is not what you want but unfortunately there is no other way. all other solutions would only cause latency and thus make live use impossible

when you have money and want a beast when you need a mixer
Behringer X AIR X18
when you need only a cheap interface for more than 2 channels Behringer UMC1820

Thanks for your help, but I`m still confused about the OBS side of things. It appears that if I have a better mixer or even three mixers the signal stills goes into one channel inside OBS and applies the filters to that channel? I do have another cheap mixer, so I guess my question is how do I get OBS to recognize that there are 2 mixers and one should have filters and the other should not? Thanks
 
Nearly every mixer will only give the main mix as output back to the PC. This is by design, as the purpose of a mixer is to handle all the audio mixing in hardware and give the fully mixed output to speakers or recording devices.

There are mixers that exist that allow you do to multi-track mixing (i.e. SoundCraft Signature 12-MTK). These are usually a lot more expensive. This one in particular will show each stereo pair as an audio input in windows, but these show up pre-fader, so the entire mixing aspect of the hardware is ignored and must be done within OBS.

There are also audio interfaces (the Focusrite Scarlet series is very popular) that have multiple inputs, which will usually allow you to pull each input separately in windows.

That all said, based on what hardware you currently have, thankfully you have subgroup and aux sends.

Assuming your mic is on channel 1, and your guitar is channel 2:
- Channel 1 routed to subgroup
- Channel 2 routed to main and subgroup
- Channel 1 aux 2 turned to mid position (adjust as necessary to avoid clipping)
- Sub 1-2 routed to phones/ctrl room

With this setup, you can connect headphones to your mixer and hear the mic/guitar mix in realtime. The mixer usb output will only include your guitar channel (since the USB can apparently only pulls the main mix for this mixer).

For your mic audio, you will need to route an audio cable from your Aux 2 output to your computer's Line In (you can get a 1/4" to 1/8" cable, or use 1/4"-1/8" adapters however you like). This will let you add the Line In device separately in OBS, and you will still have full fader control from the mixer (Aux 2 specifically... Aux 1 is pre-fader).

Thank You, I will give it a shot. Your explanation makes sense. Looking on my laptop I notice the only 1/8 connection I have is labeled Headphones, so other then usb or hdmi I do not see a way to bring a "line-in"

Hi, I was hoping I could follow up with you on this thread. Since this was posted I upgraded to a desk top and dumped the laptop, so now have real line-in connections. My question is this. I have my mixer set-up as the default device (audio Codec). What do I have to do to have OBS read the line in? When I add an audio input device OBS only see`s the mixer. I`m guessing this is something I have to set up on the windows end? Thanks again, Chuck
 
Check your windows audio devices to make sure you have the Line In device enabled. OBS won't be able to see it until windows sees that it's an active device.

mmmh another stupid idea i didnt now it works , guitar chanel with PAN poti Right, Voice with pan poti left
2 time the same source in voicemeter banana as 2 Channels 1xPAN to left and 1x PAN right and set the channels to mono so you become on the end 2x2 channel 2 Virtual cables to record it in obs !

You can also do this with the obs-rematrix filter plugin IIRC, no need for Voicemeeter.

But yeah, running the guitar through the Aux/FX Out into a dubbing cable into the system's line-in is another solution that should work. I do the same for one of my audio channels that requires realtime monitoring (audio extraction from my HDMI matrix).
