Meet mini-edge SDI

mini-edge SDI is a versatile multi-source video switcher designed for professional live production and streaming workflows. Compared with the original mini-edge, it adds four 3G-SDI inputs, an NDI bi-directional licensed port, and audio noise reduction functionality.

• Inputs
  The device provides a total of 10 input connections, including four 4K HDMI 2.0 inputs, four 3G-SDI inputs, and bi-directional UVC and NDI (license required) connectivity. It can be connected to a wide range of video sources, including PCs and cameras. For audio, mini-edge SDI supports Phantom-powered microphones, Line In, Mic inputs, and Bluetooth audio sources.
• Outputs
  Two independent HDMI outputs can be used for multiview monitoring or test output. A USB 3.0 output supports both YUY2 and MJPEG formats and can be recognized as a standard webcam for direct streaming to platforms such as WeChat Channels, Douyin, Huya, and Kuaishou.The UVC and NDI ports also support bi-directional operation. UVC can be used for USB audio recording and connection to compatible wireless speakers or microphones, such as RGBlink AI mini. The NDI port enables simultaneous encoder and decoder operation, providing greater flexibility for complex IP-based production workflows.
• Production Features
  A built-in 5.5-inch TFT display provides convenient menu navigation and multiview monitoring. The device supports dynamic output control, multiview preview, Picture-in-Picture (PiP), chroma keying, transition effects, and onboard PTZ camera control.
• Control and Streaming
  mini-edge SDI supports Web App control and integration with the TAO Cloud platform, enabling simultaneous streaming to multiple destinations. The system supports streaming to at least four platforms concurrently.

📢 Notes

- When streaming to multiple platforms simultaneously, a gigabit internet connection is recommended for optimal performance and stability.  
- For multi-platform streaming, the TAO Cloud distribution service is recommended.

1.1.1 Package Content

1 x Power Adapter	1 x USB-C Cable	2 x Mounting Foot	1 x Quick Start

1.1.2 Installation Guide

• Power Supply

The supplied power adapter is intended exclusively for powering the mini-edge SDI.

Do not use it to power additional devices simultaneously. Any system instability resulting from powering external devices with the supplied adapter is the responsibility of the user.

• Desktop Installation

For improved heat dissipation and stable placement, the included mounting feet are recommended. Installation steps:

1. Remove the white protective film from the adhesive backing.

2. Attach the mounting feet to the bottom of the device.

For applications requiring enhanced stability, we recommend the mini-EFP ultra-secure mounting solution. When used with mini-edge SDI, it provides a more stable operating environment with improved vibration resistance and portability, making it ideal for field production scenarios such as music festivals, outdoor weddings, and sporting events.

• Non-Desktop Installation

For non-desktop installation requirements, please contact your sales representative for recommendations based on your specific installation environment.

📢  Notes

[1] The USB-C port supports only one function at a time and does not support multiple devices connected through a USB hub or docking station.

[2] Phantom power should be enabled only when using a condenser microphone that requires external power. Disable phantom power before connecting other audio devices.

🚨 Hot-Plugging Warning

48V phantom power supplies operating voltage to condenser microphones through the XLR input.

Do not connect or disconnect microphones or XLR cables while 48V phantom power is enabled.

When phantom power is turned on, voltage is present on the XLR connector. Connecting or disconnecting cables under power may generate current surges that can result inloud pops or unwanted noise,microphone malfunctionordamage to the audio circuitry of the device or connected equipment.

mini-edge SDI provides a wide range of interfaces to support various production workflows.

2.3 Connecting Microphone and External Monitoring Devices

The right-side panel integrates audio input and output interfaces, supporting 2 external audio inputs and 2 audio outputs for live streaming, production, and audio mixing applications.

	👉

2.3.1 Audio Inputs

• Line In

The Line In connector uses a 6.35 mm TRS jack and supports connection to computers, smartphones,tablets, audio mixers and other audio devices.

• MIC Input

The MIC input uses a combo XLR/TRS connector and supports 48V phantom power.

It can be connected directly to powered or passive microphones.

• When connecting dynamic microphones, wireless microphone receivers, or other audio devices, phantom power must remain disabled.
• Enable phantom power only when using a condenser microphone that requires 48V power.

  • Connecting a Microphone

    1. Make sure 48V phantom power is turned off.
    2. Turn the MIC level down to minimum.
    3. Connect the XLR cable securely to the microphone and the device.
    4. Enable 48V phantom power.
    5. Gradually raise the MIC level to the desired volume.

  • Disconnecting a Microphone

    1. Turn the MIC level down to minimum.
    2. Disable 48V phantom power.
    3. Wait approximately 5–10 seconds for any residual voltage to dissipate.
    4. Disconnect the XLR cable and remove the microphone.

📢  Important
Do not connect or disconnect microphones or XLR cables while 48V phantom power is enabled, as this may damage the device or the connected microphone.

2.3.2 Audio Outputs

• Line Out: 6.35 mm main audio output.
• Headphone Output: 3.5 mm headphone monitoring output for real-time audio monitoring.
