XQSCM-404 4×4 True 4K HDMI Matrix Switcher with Seamless Switch, Scaler, HDMI Audio Matrix, Audio Extract, Auto Sensing & IR/Serial Control

The XQSCM-404 HDMI Audio Matrix enables the switching of 4 HDMI sources and then delivers the selected video stream to 1~4 HDMI monitors. You can easily control the unit via the front panel push buttons, IR controller, and serial function. This convenient solution eliminates the need for constant cable swapping, providing seamless switching functionality with no noticeable latency to enjoy a streamlined and efficient video and audio switching experience.

The Matrix switcher XQSCM-404 scaling function enables video signals to be evenly displayed on 16:9, 21:9, and 32:9 monitors without image distortion and supports almost all the mainstream monitors on the market, including FHD, QHD, and UHD high-resolution display devices.

The Audio Matrix switcher provides HDMI, SPDIF, and 3.5mm audio inputs that bring in multiple audio/video feeds supporting audio embedding and audio de-embedding functions. The audio embedding function embeds audio from a SPDIF or 3.5-mm analog stereo audio to an HDMI signal, while the audio de-embedding extracts the HDMI audio to a SPDIF or 3.5-mm stereo audio. These functions allow users to diversely incorporate the audio signal for more informative contents，such as video editing, by adding or subtracting the voiceover sound and background music.

The audio de-embedding extracts one HDMI audio, and the audio extracted can be embedded into the other HDMI signal and via the consecutively extracting and embedding process to accomplish the matrix switching.
