Studio and Streaming Setup

(Last Updated: 2023-01-14)

Anyone that knows me knows I tend to not do things the normal way.
This of course, includes my Studio and Streaming setup.
This is an overview and guide to how I do my Studio and Streaming setup.
Hopefully you will find something useful here, or at least get some entertainment from it.

Video Routing

HDMI Matrix Switch Input Configuration

Input 1: Streaming/Production PC
Input 2: Gaming PC
Input 3: Workstation Second Output - HDMI Output
Input 4: Nintendo Switch
Input 5: Sony Playstation 5
Input 6: Amazon Fire Cube
Input 7: Roku Premier
Input 8: Extra Line for temporary devices

HDMI Matrix Switch Output Configuration

Output 1: BenQ PD2700U 27” 4K Designer Monitor
Output 2: BenQ PD2700U 27” 4K Designer Monitor
Output 3: BenQ PD2700U 27” 4K Designer Monitor
Output 4: BenQ PD2700U 27” 4K Designer Monitor
Output 8: Elgato 4K60 Pro MK.2 in Streaming/Production PC

Monitors 1 and 2 are frequently changed between devices, as these are used for the Streaming/Production and Gaming PCs, consoles, etc.
Monitor 3 is almost always the second monitor for the Workstation.
Monitor 4 is almost always the first monitor for the Workstation, which connects directly to this monitor via displayport.

The Elgato 4K60 Pro MK.2 is installed in the Streaming/Production PC for capturing whatever source is needed for recording/streaming.
This lets me capture any source on the Matrix Switch.
I have the Matrix Switch output to the Elgato 4K60 Pro MK.2 scaled down to 1080p in the switch since for some reason I haven't figured out yet the card won't accept the 4k signal from the Gaming PC (although it does from everything else).

Audio Routing

Scarlett 1 Input Configuration

Channels 1/2: Usually blank, 1 is occasionally used with Kalimba.
Channels 3/4: Blue Blackout Spark SL Microphones
Channels 5/6: Moog Theremini
Channels 7/8: Raspberry Pi running OpenElec
ADAT In: ADAT Out from Scarlett 2

Scarlett 1 Output Configuration

Line Out 1/2: All but Inputs 3/4 out to Bluetooth Transmitter
Line Out 3/4: All but Inputs 3/4 out to Speakers
Line Out 7/8 (linked to front headphone out 1): Channels 3/4 to direct monitor microphones.
Line Out 9/10 (linked to front headphone out 2): Channels 5/6 to direct monitor Theremini

Scarlett 2 Input Configuration

Channels 1/2: Blank
Channels 3/4: DAC 1
Channels 5/6: DAC 2
Channels 7/8: DAC 3

Scarlett 2 Output Configuration

ADAT Out: Channels 1-8 out to Scarlett 1.

Scarlett 1 is connected to the Streaming/Production PC via USB so the microphones and instruments are available as audio sources for streaming/recording.
Scarlett 2 is not connected to USB since it is only feeding device audio to Scarlett 1 for playback, and there is currently no need to expose its channels to the PC for capture.

Lighting and Video Setup

My room has two rows of recessed lighting. This works for day to day work, but is too harsh for streaming or video recording.


The area lighting consists of 1 Elgato Key Light Air, 2 Elgato Ring Lights, 2 Elgato Light Strips, plus any light put off by monitors/keyboards/desktop toys/etc.
The Key Light Air is raised between Monitor 1 and Monitor 2 to give front lighting for PC Streaming, light for top down camera shots, and back lighting for Studio Streaming.
One Ring Light is raised between Monitor 2 and Monitor 3 to give front lighting for PC streaming and back lighting for Studio streaming.
The other Ring Light is mounted behind the Theremini to provide front lighting for Studio streaming and back lighting for PC streaming.


Video recording/streaming is done by 3 Elgato Facecams.
One is mounted on an arm between Monitor 1 and Monitor 2.
One is mounted on a flex arm above Monitor 2 for overhead or larger room streaming.
The other is mounted on an arm just behind the Theremini.

PC Input Devices

All PCs have a Ducky Shine 5 mechanical (Cherry MX Reds) keyboard and Logitech G900 Chaos Spectrum mouse.


Audio Production

Audio Recording and Editing is done using Reaper on the Streaming/Production PC.

Video Production

Studio, Streaming, and direct capture video recording is done using OBS on the Streaming/Production PC.
Other video recording is done using my Atomos Ninja V hooked up to my Olympus OM-D E-M1 Mark III camera.
Editing is done using Openshot on the Workstation PC.


Streaming is handled by OBS on the Streaming/Production PC.
I use the StreamElements plugin and the PolyPop app. I have used Restream to send to both both Twitch and YouTube on occasion.

I have 6 primary scenes configured:
Starting Soon - A picture with an audio loop
Game - Uses the Elgato 4K60 Pro MK.2 as the video/audio capture source, Facecam for face, and the Sparks for voice
Studio - Facecam for video, the Theremini (via Scarlett audio source) for audio, and the Sparks for voice
Just Chatting - Defaults to Facecam for video, has all video sources available to switch between, and the Sparks for voice
BRB - A picture with an audio loop.
Streaming Ending - A Picture with an audio loop

The sparks are the 2 channels of a single stereo audio source.
I am currently using a single OBS audio source for both scenes using the mics.
I have the source configured as mono so both mics will mix to both channels in the stream.
This is an important point. If you don’t set the source to mono, the mic being picked up will only be heard on the channel it is on on the interface - Left or Right.
Mono mode in OBS mixes both source channels to both output channels, so no matter which mic is active you will get it on both channels.
I could make 2 audio sources to fully separate the mics for the scenes (I have tested this and it works), but I don’t currently see a reason to do that because of how the pickup of the mics works and their locations.

Photo Editing

Photo processing and editing is done using Darktable and Gimp on the Workstation PC.

Hardware/Software Controls

Most control of my HDMI Matrix Switch, lighting, and streaming is done using an Elgato Stream Deck XL with accompanying software.

Advanced Launcher Configuration for HDMI Matrix Switch

The HDMI Matrix Switch has network control capabilities.
It has a web interface as well as support for raw TCP commands.
I use the Advanced Launcher plugin to run the Packet Sender tool in command line mode to control the HDMI Matrix Switch.

A note for people using a similar HDMI Matrix Switch:

  • There are older and newer versions of the switch, with differing firmware.
  • The newer version of the switch is identified by the ADVANCED label on the front.
  • The older version uses UDP instead of TCP and has a different command set.
  • Shout out to the awesome support folks at No Hassle AV who helped me out with this when I emailed on a holiday weekend trying to figure out why the UDP commands were not working!

The switch listens on TCP port 8000 for ASCII commands
To control input/output routing the command is as follows:

s in [input 1-8] av out [output 1-8]!


s in 2 av out 8!

This sends input source 2 (Gaming PC output source) to output 8 (the Atomos Connect 4k)

So in this setup the Application field in the Advanced Launcher plugin is set to the full path to (the command line executable), and the Arguments field is set to the appropriate command for the button.


-taqw 500 8000 “s in 2 av out 8!”

t: TCP
a: ASCII Mode
q: Quiet Mode
w 500: Wait 500ms for response 8000: IP and Port of HDMI Matrix Switch
“s in 2 av out 8!”: Command to send

My only complaint is that Advanced Launcher doesn’t have an option to run the commands silently in the background, so you just need to be aware that if you stream from your Gaming PC and hit one while in a game, it will likely switch you back to the desktop when the command prompt window opens to run the Packet Sender command, so don’t switch sources in the middle of a boss fight (All the more reason to use a 2-PC setup like this for streaming)!
