Omschrijving
The DOM is the central control element of the VARIODYN® D1. It has interfaces to all input/output modules, manages and controls loudspeaker circuits.
Any complex system configuration can be realized by networking several DOMs via Ethernet.
The DOM4-8 control unit is equipped with four independent amplifier channels in order to operate a total of 8 loudspeaker zones.
All power amplifiers are permanently monitored. Any faulty power amplifiers are dynamically replaced with auxiliary amplifiers. The switchover occurs automatically via the DOM.
Loudspeaker management is permanently monitored for short-circuits, ground faults, disruptions as well as impedance deviation. Faulty loudspeaker zones are non-reactively disconnected.
One DOM contains up to 260 seconds of memory for prestored announcements which can be used for alarm texts and signals (evacuation alarm, all-clear signal) and caution signals (tones). The volume of each source and each amplifier channel can be adjusted. Additional filters such as parametric equalizers, high and low-pass filters as well as delays are also available. All faults are identified, displayed and logged within seconds.
