4.2 Paging Microphones and PA Elements (ACSI Bus)
Figure 43 - Public Address Connection Devices
The equipment has a connection for Public Address elements, such as microphones, remote
panels, etc. The type of connection for all these elements is in bus mode. Each device is
connected one after another, up to a maximum of 8 devices, and a maximum total distance of
cable of 1000m.
Each device has a direction selector. Depending on the configured priority set in the device, it
will allow the user to occupy the channel when is occupied by other devices. To configure the
priority of each device inside the bus, the configuration application must be used. If no priority
has been configured, the direction in which each device is set up inside the bus, will be used as
order of priority. When, in an ACSI bus there are multi-zone microphones and remote panels,
the latter would be set as a higher priority in the bus, implementing therefore the priority order
between different panels, and between different microphones.
NOTE: When the ACSI bus is being used, the audio input nº5 will be disabled (see section
4.3 FlexNet Connection
FlexNet is a protocol of communication developed by Audio Tech that allows the transmission of
both digital audio and control data, using a standard Ethernet network. The system ensures the
maximum level of quality and reliability, as it is based on the transmission of digital audio using
the CobraNet.
With FlexNet, all the compatible devices can be interconnected without the need of an external
network. To provide a greater robustness and simplicity, in the case of failure in the link, the
connection between devices will still continue to maintain its integrity by automatic management
of primary and redundant links of each system.
Through FlexNet, from the system controller, the user will have access to the configuration,
control and basic motorization of the devices connected in the system. For a more advanced
