Description
The automatic volume control is done by a matching transformer of 100V and a switch with 11 steps (10 control steps, each 3 decibel + 1 zero position).
The switches are overwindable in order to avoid wilful demolition. The volume controls come with emergency call relay. They are suitable for every standard 55mm mount socket.
Cover plates and frames are in a modern, discreet design.
If a building project is planned to be equipped with the same surface, use of volume controls without cover plate and frame is possible, as shown on the right. If necessary, the attached control knob can also be changed.
