The TA-B14SA is a professional 1×4 HDMI 2.0 splitter designed to distribute a single HDMI source to four HDMI displays simultaneously. It supports video resolutions up to 4K@60Hz 4:4:4, providing high-quality video distribution for professional AV, commercial display and presentation applications.

The splitter features an integrated 4K-to-1080P downscaler, allowing the incoming 4K signal to be converted to 1080P when required. Users can select between bypass mode and 4K-to-1080P downscaling using the front-panel dial switch.

For flexible AV integration, the TA-B14SA provides audio extraction through both 3.5mm analog L/R and optical S/PDIF outputs. This allows audio from the HDMI source to be connected directly to powered speakers, amplifiers or other audio systems.

The device also supports AUTO and COPY EDID modes for managing compatibility between the HDMI source and connected displays. AUTO mode compares the EDID information from the four outputs, while COPY mode uses the EDID from the highest-priority connected display output.
