    Required Accessories

    The SDM-277p is an SDI to NTSC/PAL or PAL-M and analog audio converter. It is ideal for standalone video monitoring and de-embedding applications of an SDI signal with embedded audio.

    The SDM-277p provides a re-clocked SDI output (loop), built-in color bars generator and automatic input format detection (525 or 625). The SDM-277p can extract any AES pair in a SDI stream using a 20-bit quality D to A converter. The SDM-277p/U version provides unbalanced audio outputs on RCA plugs for convenient connection to monitor.
