Comelit 4933 Video Concentrator-Amplifier for Simplebus 2

Comelit 4933 Video Concentrator-Amplifier for Simplebus 2 Systems

The Comelit 4933 is a 6-output video concentrator-amplifier for Simplebus 2 door entry systems. It provides star distribution of the video signal, directing and amplifying the signal only towards the riser branch involved in the active communication. This selective approach reduces unnecessary signal loading across the system.

The 4933 regenerates and amplifies the video signal with two independently adjustable gain levels across all 6 outputs, enabling extended operating distances on larger installations. Riser outputs in use must be programmed manually or via Art. 1249B software. The unit is only to be mounted on the system section feeding into the mixers (Art. 4888C, Simplebus 1 section).

Compatible with all Simplebus 2 functions and products. Housed in an 8-module DIN enclosure with 115-230 VAC mains input.
