• Interface to Praesideo basic amplifiers
• Up to 16 audio channels
• Redundant fiber optic network connection
• Control input and output connections
• Complete supervision

The PRS-16MCI is part of the Praesideo network and acts as an interface to the Praesideo basic amplifiers that do not provide network connectivity. The unit is intended for public address and emergency sound systems. The multichannel interface provides 16 configurable output channels (14 main outputs and two spare outputs). It provides the audio signals to the basic amplifiers and has full control over the amplifiers. It supervises itself and the connected basic amplifiers, and reports fault events to the Praesideo network controller. The unit should be mounted in a 19″-rack with the included mounting brackets.

• Fully supervised DC‑power supply with integrated fail-safe redundancy
• Unique single 12 V battery backup solution
• Integrated 6‑port Ethernet switch on RJ45 and SFP
• General purpose control inputs and outputs
• Backup lifeline for connected amplifiers

This compact device combines multiple support functions to power and serve other PRAESENSA system devices. It can be used in a centralized system, but it is an enabler for decentralized system topologies with several smaller racks or cabinets located across the premises, to reduce loudspeaker cabling costs significantly. It provides DC‑power supply to connected amplifiers and peripherals from the mains, with a standards compliant charger for a single 12 V backup battery, saving on installation and battery maintenance costs. The integrated 6‑port Ethernet switch, with glass fiber support, facilitates easy interconnection of decentralized clusters of devices. Configurable, supervised control inputs and voltage‑free control outputs are available as interface to external equipment. Its OMNEO interface for control and fault reporting also provides an analog audio backup lifeline for the connected amplifiers.

The PRM-USTB is a professional multi-source music player intended to be used as background music source for public address and commercial audio applications. It has USB interface, SD card input for playing stored music files, tuner for FM frequency band broadcast receiver and Bluetooth® receiver for direct music streaming from a mobile device. It is used in hotels, shops, supermarkets, restaurants, bars, canteens, gyms, showrooms, and other places
where background music creates the right atmosphere.

The PLE-SDT Plena Easy Line SD Tuner BGM source is the ideal high‑quality source for background music
(BGM) in public address systems. It provides hours of uninterrupted music for professional systems. Designed without moving parts, it can be used in systems that are on for long periods. It is designed to be used with non-volatile steady state flash memory.

• Low smoke/zero halogen (LSZH) sheet material
• Wide temperature range operation

The LBB4416/00 is a network cable with two plastic fibers for data communication and two copper cores for power supply. It is 100 meters long, and comes without network connectors. LBB4417/00 connectors are fitted after the cable has been cut to the required length

• Public address and emergency sound system control unit
• Control and routing of 28 simultaneous audio channels
• Ethernet interface for configuration, control, diagnostics, and logging
• Digital storage for pre‑recorded messages
• EN 54‑16 and ISO 7240‑16 system certification

The network control unit is the heart of the Praesideo system. The unit routes up to 28 simultaneous audio channels, delivers power to the system, reports faults, and controls the system. Audio inputs can be announcements from call stations, background music, or local audio. The network control unit can be configured for the most complex public address systems. The configuration can be done comfortably and efficiently via a PC. The PC is only needed for configuration. The controller can operate independently of the PC. However, the controller can use a PC to display information on the system status using the software, supplied with the unit. The unit can be freestanding on a tabletop or mounted in a 19″ rack. The PRS‑NCO3 network controller needs PRS‑SW software version 4.0 or higher.
