AVerMedia Video Audio Switcher MT300 — 2× HDMI inputs, HDMI output

AVerMedia MT300 is a compact video and audio switcher that accepts two HDMI inputs and provides a single HDMI output for simple, reliable source selection. The device is intended for small studios, meeting rooms and live streaming setups where quick switching between two HDMI sources is required without reconnecting cables. The MT300 routes both video and embedded audio over HDMI and supports straightforward source changes for presentations, broadcasts and content capture.

Advantages

The MT300 offers a small footprint and an intuitive control interface for switching between two HDMI sources. It preserves HDMI video and embedded audio integrity while minimizing cable handling and setup time. The unit operates with low power consumption and provides consistent signal transmission to an HDMI-equipped display, recorder or encoder, reducing the need for additional AV routing equipment.

How to use

Connect up to two HDMI source devices to the MT300 inputs and connect the HDMI output to your display, recorder or encoder. Power the unit using the supplied external adapter. Use the front-panel control to select the active input; the device will route the selected HDMI video and embedded audio to the output. Verify display resolution and audio compatibility on connected devices to ensure optimal signal transmission. When connecting to recording or streaming hardware, confirm input detection in the capture software or encoder before starting a session.

Recommendations

For reliable operation, use high-quality HDMI cables and confirm that all connected devices support the intended resolution and audio format. Place the MT300 in a well-ventilated area, avoid stacking heavy equipment on top of it, and power-cycle connected devices if signal handover fails. For best results in streaming or recording workflows, set consistent resolution and frame-rate settings across sources before switching.
