Introducing MainStream: The Ultimate Digital Mixer for Podcasting and Streaming
MainStream by Mackie is the perfect solution for all your streaming and podcasting needs. With its powerful features, it enables you to get the desired results in no time. Here are some ways you can use MainStream:

All-In-One Livestream
MainStream integrates all your devices, including your mic/headset, camera, and other sources, allowing you to control your live stream from a single device.

Console Gaming Setup
MainStream is great for running a professional live streaming battle station, including a high-end DSLR camera, USB webcam, high-quality XLR broadcast mic, and headphones. It connects to your PC with one USB-C cable, making it easy to set up.

PC Gaming Setup
MainStream acts as a capture card for Switch, Xbox, PlayStation, and other gaming consoles. You can stream with a lightweight laptop and your headset for a low-cost, high-quality option.

Just Chatting Setup
MainStream is flexible and perfect for any type of live stream. This "Just Chatting" setup uses a DSLR camera, USB mic, and a smartphone for chatting with call-in guests. (Mix Minus ensures the caller doesn’t hear an echo).

Matrix Software
The free Matrix software is entirely optional, but extremely powerful. It allows you to add up to 6 virtual inputs (like Discord or Spotify) and 4 hardware inputs and route them all to your live stream. You can even use Matrix with devices other than MainStream.

Keep Your Controls at Your Fingertips
MainStream gives you tactile control over levels, plus a row of programmable keys for triggering samples and transitions. This way, you can keep your controls at your fingertips and avoid menu diving on your computer.

HDMI In & Thru
MainStream features an HDMI input with a video capture card (1080p x 60 fps) and pristine HDMI passthrough for your monitor (4K x 60 fps) so you can stream live and game at high quality.

USB-C HUB for Your Devices
MainStream allows you to consolidate and streamline your entire setup with two USB-C inputs for extra cameras, USB microphones, thumb drives, and any other USB devices you want to connect to your live streaming computer while only taking up one port.

Analog Inputs
MainStream includes a main mic input (+60 dB), chat headset input, smartphone input for live streaming phone calls, headphone output, and stereo line outs that are perfect for speakers.
