POLYVALENT SPACES (Recording studios-Auditorium-Sale conferneze-Classrooms meeting) For multipurpose spaces R.M. realizes air conditioning systems that guarantee an absolutely low noise level according to NC or NR noise weighting curves, which differ according to the intended use of the environments. In this way a correct acoustic reference without noise is offered. The whole design phase is developed in harmony with the acoustic project. To achieve this, specific equipment is selected according to the space available or made to measure (the air conditioning unit - aeraulic ducts, silencers and acoustic traps) to effectively control the noise level of the air. To complete the environments, R.M. designs and builds structured cabling architectures as well as for normal network flows, suitable for audio video signals in the new high resolution standards.
