The versatile audio matrix system DRM-884 ... A general solution for versatile multi-room PA concepts with fixed installations in hotels, restaurants and bars, conference rooms, schools, sports and fitness centres.
The matrix system DRM-884 is a professional tool with extensive features which easily meets any requirement: users can combine signal sources, play one source in several zones or several sources in one zone, adjust the volume in each zone and much more. The audio matrix router DRM-884 is the heart of the system which is able to distribute a maximum of 8 analogue and 4 digital audio sources to just as many output zones, any assignment possible. You can either connect active speakers or a power amplifier with passive speakers to the output zones via Phoenix terminals.
The multifunctional matrix system is controlled via wall panels: modules DRM-884VAP and DRM-884VP allow you to remotely access, e.g. level and program selection in the different zones. The wall panel DRM-884IOP allows for other connection options are available, e.g. at the location of the PA application. The zone paging microphone DRM-884RC with zone selection can be connected for announcements.
Expand your options with the matrix system: if you need a larger number of inputs and outputs, the system can be extended from a maximum of 16 x DRM-884 and optional Dante ^® module to 192 inputs x 192 outputs by means of cascading.
With the Dante ^® extension module DRM-884DTM, the DRM-884 can quickly and easily be inserted into a Dante ^® audio network. For this purpose, there are an additional 8 digital inputs or 8 digital outputs available which can be assigned to either an analogue output or a Dante ^® channel. Audio matrix router
