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
Audio can be recorded at all speeds.  To hear the
playback sound, use the 06, A18 or A30 speed dur-
ing playback.

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, unbal-
anced).

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.
