To connect multiple SDI devices to the singmai SM20 Distribution Amplifier and ensure proper signal distribution, follow these steps:
1. Connect the SM20 to the supplied AC/DC adaptor using the appropriate power lead for your country. The adaptor accepts AC between 100 and 240VAC.
2. Connect the 5VDC jack from the adaptor to the +5VDC ‘Power in’ socket on the SM20.
3. Connect an SDI video input to the ‘SDI In’ BNC port on the SM20. The SM20 supports various SDI standards such as SMPTE 259M, SMPTE 292M, SMPTE 296M, SMPTE 372M, and SMPTE 425M.
4. You can connect any or all of the four ‘SDI Out’ BNC ports to your SDI devices. Each ‘SDI Out’ port provides an equalized and re-clocked copy of the video input.
By following these steps, you can effectively distribute SDI signals to multiple devices using the singmai SM20 Distribution Amplifier. For more detailed technical information and specifications, refer to the user manual provided with the product.
