INTRODUCTION
The VDA401 is a high quality 1-input looping to 4-output video/audio distribution amplifier. All outputs are short circuit protected and each can drive a 75
ohm terminated load.
A level adjustment for the video/audio outputs is accessible on the front
panel. This adjustment gives full range amplification or attenuation depending on the system requirements. All outputs are adjusted simultaneously by
this one control.
All video/audio outputs are AC-coupled. Each video/audio output is driven by
an individual 75 ohm video driver. All specifications are measured at 75 ohm
termination
The compact metal enclosure maintains top performance in all kinds of
mounting situations. A small UL/CSA-rated wall transformer supplies 912VDC to the unit or 24Vac input.

ADJUSTABLE GAIN
The single turn potentiometer on the front panel is used to control amplification
or attenuates the overall gain or video level of the signal. This can recover
attenuated signals when video ouput is too high.
The video level is about 0-2V P-P adjustable using the potentiometer. The
video standard is RS-170A / NTSC or CCIR / PAL video format.
Use a screw driver and turn the potentiometer clockwise to increase the video
level and counterclockwise to reduce the video level output.
CONNECTIONS
The video input and output are located on the rear of the unit. The video input
connects to the video source via the right BNC connector. The video output
connects to a display, recording device, switcher, or other equipment via the
other four BNC connectors.
