To connect multiple SDI devices to the Singmai SM20 Distribution Amplifier and maintain signal integrity, follow these steps: First, connect the included AC/DC power adapter to a power outlet using the appropriate power lead for your region. The adapter is designed to handle AC voltages between 100 and 240VAC. Second, plug the 5VDC jack from the adapter into the +5VDC 'Power in' socket on the SM20. Next, connect your SDI video source to the 'SDI In' BNC port on the SM20. The SM20 is compatible with various SDI standards, including SMPTE 259M, SMPTE 292M, SMPTE 296M, SMPTE 372M, and SMPTE 425M. Finally, connect any or all of the four 'SDI Out' BNC ports to your SDI-enabled devices. Each 'SDI Out' port delivers an equalized and re-clocked copy of the SDI input signal, ensuring reliable signal distribution. For in-depth technical specifications and further details, please consult the Singmai SM20 user manual.
