So you are looking for a way to use your headset microphone for streaming or want to use your Mixamp you just got to merge all of your audio such as your headset microphone, Party Chat, and Game Audio to output to stream. This tutorial will show you how to do this with Streamlabs OBS with the Astro Command Software.

Let's cover some prerequisite's to get this to work!

  1. Astro Pro Mixamp TR Edition
  2. Streamlabs OBS
  3. One or two 3.5mm auxiliary cables with a standard 3-pole connection (length can vary but just make sure it's long enough to cover the distance necessary)
  4. Astro Command Center software
  • A capture card if you are capturing console gameplay, for tutorial purposes we will be referring to Elgato.
This guide assumes you are setting this up for console streaming. For a two PC setup, this guide is still applicable if you do not have a dedicated streaming microphone.

Guide:

You would need to set up your audio to work with Astro Command Center software along with any other sounds you would like to play on your stream from your console.

To do this, plug your Astro Mixamp Pro into your PC with the USB cable, then put it into PC mode by holding the power button down for 3-4 seconds and the power button color should change.

(If this is the first time you are connecting it, you may need to perform a firmware update, feel free to do this)

If you just want it to be your microphone you would want it to look something like this:



If you want Game or Chat Audio then you would want it to look something like this:



Once you have configured the sounds you would like from your Astro Mixamp you would click Sync to Device


NOTE: if you plan on listening to your PC audio with the Aux port for your alerts from Streamlabs OBS then you would want to make sure that the Stream Port audio for this is at 0 to prevent an echo, refer to the above screenshot and see the Aux slider.

Once you are done, be sure to plug your Mixamp back into your console or computer.

Then lastly what you are going to want to do is go into Streamlabs OBS and change your Elgato to Analog Audio.

1. Go to your Elgato Game Capture Software and click the gear icon to the right of where you see the name of your Capture Card
2. Then click Audio Input and select Analog Audio.



3. You then need to click on Configure Video in the Video Capture Device Properties:



This will only work with the Elgato HD60S as it has an analog audio input.

For more information about getting audio to work with Streamlabs OBS and/or other capture card products and/or to set it as a Line-in device under "Use custom audio device" see here.

NOTE: If you are using the above Line-in device method and you are experiencing static or some type of noise with your stream port you may also need a ground loop isolator.

That's it! You're done 😄

This was a great read! Very straight to the point and easy to understand! I’m gaming on my PS4 and streaming to twitch via pc with the Astro a40 + mix amp headset. The only thing I’m having a problem with is that MY mic audio output to stream is low, everyone else in party/game chat is fine. My question is, can I turn down my mic stream port output in ACC to zero and just use an external mic?

Hello there!

You can do that in the Astro Command Center, yep yep! Can do that in the screenshot below, and set the volume for your microphone to zero then click "Sync to Device".

Hi! How would I do this with a dual PC setup and an Elgato HD60Pro?

Hey there! You would want to set your Astro's Stream Port settings to look something like this and click Sync to Device:



You would then use the line-in port on your streaming computer's motherboard. Then you would check the option for Use custom audio device and under Audio Device you would select Line In in the Video Capture Device Properties in Streamlabs OBS.

Would all the cables I would need come with the purchase of the Astro A40 TR Mixamp? Or would I need to buy them? And thank you for the quick reply!

You would need a few 3.5mm auxiliary cables and that would be it, I'd say get 2-3 premium cables and you should be good to go! Also, be sure to check my initial reply to you, I included some more information. One cable would be needed for the Stream Port, and an additional one could be used for the Aux port to plug in the Streaming PC's audio to the Mixamp so you can get both PC's audio in your headset.
Hello Zam,
What are all the cables I will need for this to work properly? Is it just what comes with the mixamp and the extra aux cables? I have a blue yeti mic for my stream to hear me talk. Also I'm using an Steel Series Arctis 5 headset for my game and chat audio. Will that work with the amp and everything along with it?
Thank you for your time
I saw your note about lowering the volume if I want to listen to alerts from my PC through the mixamp. I am getting the echo. How do I lower the volume without lowering the volume on my stream? This is a great howto. Thank you for your help.

@ApitomyGG As what was stated before, you would need a couple of 3.5 mm auxiliary cables. 😀 As for using a different headset, you may be able to use it and if you have it (or can borrow a friend's to test) it's worth a shot!

@VinnySoFresh On what audio source are you getting the echo?
@Sarah Ok. I'll try my best to explain since I'm feeling like a noob. I have chat and game audio going thru the stream port on my mixamp to my elgato to my streaming computer with streamlabs. I would like to hear notifications from streamlabs from the headphone jack on the streaming computer through my a40s connected to the mixamp by the aux connection. When I do that, I get the echo. I have the elgato audio on it's own track. I don't know how to lower the volume or mute it without affecting the audio on stream. I hope I make sense. I appreciate your help.
Okay maybe i'm stupd- But where do I plug these Aux cords to and from? I see the 3.5mm Jack on the Elgato. I have a mixamp TR. I just have no idea where i'm plugging everything in. If I switch to Analog my audio is gone. Thanks.
does it matter if the micro usb to usb cable is plugged into the console or pc? (is it just for power or is it transferring some audio?

First off apologies all for the delayed response.

@VinnySoFresh - You would have to switch the Mixamp to PC mode and it would need to be plugged into the computer that has the Astro command software on it, then go to the Stream Port and move the Volume slider to the Aux port of the Mixamp to zero and sync it to the device as this is why you're getting your echo.

@ProjectKayo - That depends on your hardware and where you are routing your audio. For the Stream Port, it goes to the Line-In of the streaming computer or the Elgato HD 60S. Line-In port on your PC is typically represented by a blue 3.5mm port on the back of the motherboard. The aux port on the Mixamp itself is meant for audio into it so you can hear it in your headphones, you can plug whatever you want to hear into this. For instance, if it's your dedicated streaming PC, it would go from the headphone jack of the PC (indicted by the headphone symbol on the front I/O of the computer, or typically the green 3.5mm jack on the back of the motherboard of a computer) to the Mixamps Aux port. If you need further help with that, would recommend learning what ports your PC has or what different ports are for.

@RatmLoud - For console, both the optical and USB would be plugged into the Mixamp, otherwise you can't talk to people in-game/your party. You would use the Stream Port and this guide to route your audio however you need it to be routed.
