Chapter 1 Overview
connector on the other device before making the
connection to this unit.
b SDI (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.
c SDI (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.
d DIGITAL 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.
e DIGITAL 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.
C Analog audio signal input/output section
a AUDIO IN LEVEL/600 Ω switches
Set these switches for each channel as shown in the
following table, according to the audio input levels to the
AUDIO IN CH-1 to CH-4 connectors and the required
impedance.
a) Selectable on DSR-1800AP only
b AUDIO 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).
c AUDIO 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)).
d AUDIO MONITOR OUT connector (RCA phono
jack)
This connector outputs audio signals for monitoring. The
audio signals to be output from this connector can be
