connector on the other device before making the connection to this unit.

bSDI (Serial Digital Interface) IN (input) and active through output connectors (BNC type) (optional

DSBK-1801 SDI/AES/EBU Input/Output Board required)

Input digital video and audio signals in SDI format to the left-hand connector. The right-hand connector is for an active-through connection.

cSDI (Serial Digital Interface) OUT connectors (BNC type) (optional DSBK-1801 SDI/AES/EBU Input/Output Board required)

Output SDI-format digital video and audio signals. The same signals are output from both connectors.

dDIGITAL AUDIO (AES/EBU) IN connectors

(BNC type) (optional DSBK-1801 SDI/AES/EBU Input/Output Board required)

Input digital audio signals in AES/EBU format to these connectors.

The left-hand connector (CH-1/2) is for audio channels 1 and 2, and the right-hand connector (CH-3/4) is for audio channels 3 and 4.

eDIGITAL AUDIO (AES/EBU) OUT connectors

(BNC type) (optional DSBK-1801 SDI/AES/EBU Input/Output Board required)

These connectors output digital audio signals in AES/EBU format.

The left-hand connector (CH-1/2) is for audio channels 1 and 2, and the right-hand connector (CH-3/4) is for audio channels 3 and 4.

bAUDIO IN CH-1 (channel 1) to CH-4 connectors

(XLR 3-pin, female)

Use these connectors to connect separate channels of analog audio input from a player VCR or other external audio equipment.

You can switch the audio input level setting with the LEVEL SELECT menu item (see page 71).

cAUDIO OUT CH-1 (channel 1) to CH-4 connectors

(XLR 3-pin, male)

These connectors output channel-1 to channel-4 analog audio signals, respectively.

It is possible to use the AUDIO OUT CH-3 and AUDIO OUT CH-4 connectors for audio monitor output for channels 1 and 2, respectively (use the OUTPUT CH3/4 menu item (see page 71)).
