INSTALLATION
VIDEO CONNECTIONS
Use coaxial cables when connecting a camera and a
monitor to this VCR.
Note: Long cable runs to distant cameras may
cause signal deterioration and/or sync discrep-
ancies. If these problems occur, use video line
amplifiers and/or cameras having phase-adjustable
line-locked vertical sync.
Video Input
In single camera systems, connect the camera to the
Video IN BNC terminal on the VCR rear panel. Use
of a 2:1 interlace camera is highly recommended;
otherwise, the monitor will show vertical distortion
of the TIME/DATE characters.
In multiple camera systems, connect the switcher
output to the Video IN BNC terminal. Because mul-
tiple camera systems require synchronization, use
of cameras having line-locked vertical sync or a gen-
locked master drive/sync source is highly re-
commended. The use of vertical interval switchers
is also recommended.
Video Output
Connect the monitor to the Video OUT BNC terminal
on the rear panel.
AUDIO CONNECTIONS
Note: Audio recording can be performed at the 09
and 27-hour recording speeds and audio playback at
the 09 and 27 speeds.
Audio In: Accepts an audio signal from a camera,
external sound equipment, or another recorder
(Line: –8 dBm, 50 kohm).
Audio Out: Provides an audio output for a monitor
or another recorder (–9 dBm, 600 ohm, unbalanced).
USING THE 15-PIN ADAPTER
Attach the wires of the alarm switch, door sen-
sor or warning lamp to the 15-pin adapter
using screws.
After connection, connect the adapter to the
EXTERNAL INTERFACE jack on the rear of the
VCR.
