Chapter 1 Overview
A Analog video/audio signal input section (optional DSBK-1505 Analog Input Board)
The connectors in this section are available when the
optional DSBK-1505 board is installed.
a VIDEO IN connectors (BNC type)
There are the following VIDEO IN connectors for
inputting analog video signals:
• Y/CPST (loop-through connectors)
•R
−Y/C
•B
−Y
The signals you can connect to these connectors depend on
the selection made with the VIDEO button in the video/
audio input selection section. The selection is indicated by
the VIDEO indicators in the INPUT signal display section.
The analog video signals that can be input to these
connectors are as follows.
When COMPOSITE is selected:
The two Y/CPST connectors are loop-through
connectors. When using the signal input to the left Y/
CPST connector as a reference video signal, for
example, you can bridge-connect the signal to other
equipment via the right Y/CPST connector (marked
). When no connection is made to the right Y/
CPST connector, the left Y/CPST connector is
terminated with an impedance of 75 Ω automatically.
When S VIDEO is selected:
When Y
–R,B is selected:
b AUDIO IN 1/3 and AUDIO IN 2/4 connectors
(XLR-3 pin, female)
Use these connectors to input analog audio signals from an
external video cassette player or other audio equipment.
The signals input to these connectors are recorded on the
audio channels determined by the current audio recording
mode, as follows.
When in 2 CH (48 kHz) mode:
When in 4 CH (32 kHz) mode:
You can switch the audio recording mode with the REC
MODE menu item (see page 66). The selection is indicated
by the REC MODE display on the front panel.
