Philips LTC 3963/51 manual Video Connections, Audio Connections, Using the 15-PIN Adapter

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.
