Connect A/V Sources

External audio and video sources are connected to the appropriate inputs on 3Play’s backplate,or, in the case of 3Play Mini, the front.

1. Connect video sources to the appropriate connectors in the VIDEO IN section, whether SDI, Component, Y/C (S-Video), Composite (may require RCA to BNC adapter) or HDMI (3Play Mini).
2. SDI/HDMI – Attach the SDI source connectors to BNC connectors marked SDI

in the Video In group

1. Component – Attach the appropriate BNC connectors from your sources to all three analog BNC connectors (labeled Y, Pb and Pr) in each column in the Video In group.
2. Y/C – If your S-Video equipment and cabling has the usual 4-pin mini-DIN connectors, you will need an S-Video to dual BNC adapter. To connect Y/C sources, attach the Y (luma) connector of your source to the second analog BNC connector (labeled Pb). Attach the source’s C (chroma) connector to the bottom connector (labeled Pr).
3. Composite - Attach the composite source’s connector (may require an RCA to BNC adapter) to the second connector (labeled Y).

Note: The video broadcast standard (such as NTSC, NTSC-J or PAL) of all video sources connected for a given session must be the same.

2. To input analog audio along with the video, connect the external audio sources to the XLR or ¼” connectors in the Audio In group box. Two connectors, labeled “a” and “b”, are provided for each input group. We’ll discuss audio Connection Type options a bit later, in Section 3.10.

Digital Audio Note: To connect AES/EBU (a.k.a., AES3) audio source, use the BNC connectors in the Digital Audio (AES) section. SDI video sources with embedded audio do not need a separate audio connection.
