Make Connections

Mackie MainStream is the easiest way to start a pro-quality live stream, integrating video, audio, and stream control into a single, powerful device. Simply connect your mic, game feed, and other sources straight into Mackie MainStream for a sleek, all-in-one solution that puts essential controls right at your fingertips.

HDMI In and Thru

Mackie 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 a high quality. It's a shame what happened to the radio star, but it's time to move on.

USB-C Hub for Your Devices

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

It wouldn't be Mackie without high-quality analog audio. In addition to the main mic input (+60 dB), MainStream includes a chat headset input, smartphone input for live streaming phone calls, a headphone output, and stereo line outs that are perfect for speakers.

Keep Your Controls at Your Fingertips

When you're streaming live, the last thing you want is to end up menu diving on your computer. MainStream gives you tactile control over levels, plus a row of programmable keys for triggering samples and transitions.

Gaming Console Streaming Setup

MainStream acts as a capture card for Switch, Xbox, PlayStation and other gaming consoles. Just connect your console to HDMI in and the HDMI passthrough to your television. You can stream with a lightweight laptop and your headset for a low-cost, high-quality option.

Gaming PC Streaming Setup

Run a professional live streaming battle station through Mackie MainStream, including a high-end DSLR camera through the HDMI, USB webcam for an extra angle, plus a high-quality XLR broadcast mic and headphones. It all connects to your PC with one USB-C cable.

Just Chatting Streaming Setup

The flexibility of Mackie MainStream makes it the perfect interface for any type of stream. This just-chatting setup uses a DSLR camera, USB mic, and a smartphone for chatting with a call-in guest. (Mix minus ensures the caller doesn't hear an echo).

Matrix Software

The free Matrix software is entirely optional, but extremely powerful. Add up to 6 virtual inputs (like Discord or Spotify) and 4 hardware inputs and route them all to your live stream. Add vocal effects, tweak your mix and create and trigger samples with 24 virtual pads. You can even use Matrix with devices other than MainStream. It won't get jealous.
