Video amplifier
Gira system devices

Merkmale:
- The video amplifier is used to extend the range of Gira door communication
systems to include video function.
- It increases the volume of the incoming video signal to the maximum
permissible bus volume and outputs it at the output. thereby compensating for
the line attenuation from the source of the video signal to the input of the
video amplifier.

- Surface-mounted (in a standard junction box).
- Flush-mounted (in a device box).
- As a DRA device (using the DRA adapter enclosed).
