Description
Bosch PVA 4R24 Paviro system Router in Bangladesh
The internal supervision system monitors the functions and operation of both itself and the connected devices and enables re-routing of a spare amplifier channel, replacing an amplifier channel that has reported a fault.
Fault conditions are reported to the connected system controller for operational control and logging purposes and the PVA4R24 router supports single line assignment or redundant group A/B switching.
Routing of at least 4 channels into eight 100V audio inputs to 24 loudspeaker line outputs is possible and the loudspeaker line outputs are divided into clusters of 6. Each cluster allows the same or a different two-channel operation mode to ensure continuous and/or different music into different zones.
Each router cluster can also operate as a 2-in-6 matrix (4 channel input matrix to 2-in 6 cluster).
Integrated loudspeaker supervision eliminates the requirement of amplifier power for supervision, resulting in very low power consumption.
