Variodyn is the name of a paging system. the name itself was introduced about 1975 at germany for an analog paging system developed by siemens.
- status: not in production
history of the variodyn system
- Variodyn
- the first system was an fully analog system, consisting of several components pre amplifiers, mixers and power amplifiers. the paging behavior of an installation was made by wiring contacts and relays. line relays were installed to get better control were the signal is distributed and get a better cost effort due power amplifiers are expensive. with the line relays it was possible to drive more lines, not using all the lines at the same time. i have no more information about the components.
- Variodyn 2000, developed 1985 by siemens
- this was also an analog system. the new innovation was to design all the components mechanic and electrical compatible, so the components could be combined in thousands of variations by wiring at the rack. the components also had the necessary paging switches onboard and used electronic swiches instead of relays to switch audio. there was also a small audio matrix (4x4) supported by each device, and the audio switches were easy controllable by external contacts. the main behavior of the system had to be implemented by relays witch were supported by some devices implementing often used behavior.
- status: not in production
- Variodyn 2030, developed 1987 by siemens
- this is an extension for the variodyn 2000 devices. all the devices were designed to plug on a interface for digital control. with this interface the audio switches of the devices were controllable by a microprocessor. new components were developed to get user interaction from keys and switches and show the system's operating states via lights to the user. the software was then controlling the behavior of the audio switches and allowed then more complex behavior to implement than it was possible using only relays.
- status: not in production
- Variodyn 3000, developed 1991 by siemens
- this is an analog system digitally controlled. the innovation was to replace the expensive parallel control bus used by the Variodyn 2000 system by a serial bus. this reduced also rack wiring complexity and allowed to build up larger systems. all the components use relays to switch audio and allows to control digitally the audio volume at each device. a more powerful processor controlling the behavior was also developed. then the software was enabled with a lot of features for paging systems. a configuration phase was introduced defining the behavior and devices installed at the system.
- status: not in production
- Variodyn D1, developed 2004 by av digital
- this is a fully digital distributed system. only 10 different components allow to build small installations and grow up to very large installations. the benefits are detailed described at several websites. the system has overridden the older one. several hundred installations are running worldwide.
- status: in production
