Streamline Your Livestream Production

The GoStream Duet features a comprehensive, tactile control panel with numerous buttons, PVW and PGM select buttons, knobs, and a fader. It also features recording to SD card and external USB SSD, which also support the playback function, reducing the number of required devices needed to facilitate your livestream.

Supports Three Simultaneous Streams

Livestream to three different platforms such as YouTube or Twitch simultaneously using the integrated Ethernet port on the GoStream. Connect a USB webcam to the USB-input and output that feed via OBS, VMix, or Zoom using the USB-C output port.

Output up to Five Channels

Select up to five video input sources from the SD card, SSD, HDMI, SDI, USB, or NDI|HX inputs, such as cameras, streams, switchers, and UVC sources, and output them to a monitor or projector for simultaneous presentation, or connect an optional Stream Deck or built-in WebGUI.

Built-In Audio Mixer

An internal audio mixer supports seven channels of embedded and input audio sources, with audio sources coming from the SDI and HDMI inputs, one from the AUX input, and two from dedicated 3.5mm TRS microphone ports. Mix the inputs into the program output using the On/Off or AFV controls on the switcher and adjust parameters like gain, balance, and fade. Monitor audio from a selected source using the headphone input.

Utilize up to Nine Effects

The GoStream Duet supports nine special effects including Super Source, upstream keyers, downstream keyers, Chroma keyers, transitions, and a still image generator. Craft visually appealing, multi-layered effects tailored to your production. Use the eight Macro Memories to record specific composition functions and set them as custom presets for efficient recall.
