The SNG-PR is the heart of the Sinergia system, the unit is a PA/VA network processor that comes with 6 slots for modular audio I/O expansion cards, including analog telephone card, remote network PA card, 4-channel line/microphone input, 4-channel line output, 2-channel line/microphone input, 2-channel line input, line output, 4-channel digital I/O, VoIP, and AES/EBU.

Thanks to the ATEÏS-Net network architecture, all audio processing is carried out in the digital domain.
It is possible to start with a small system in the initial stage and later expand it simply by adding the required SNG-PR processor or SNG-AM modular amplification units to the existing network (max. 256
SNG-PR/SNG-AM units in redundant loop cabling). Additionally, the SNG-PR processor is designed to provide total redundancy reliability and offer complete real-time monitoring. If the main SNG-PR processor fails, there is an automatic switch to the redundant SNG-PR processor to ensure uninterrupted operation.

Digital signal processing allows for significant audio quality improvements. Communication between units is via 100m (RJ45
plug, STP CAT5 or higher), 2 km (multimode fiber optic), and 20 km (single-mode fiber optic). The system cabling is a closed loop, enabling
redundancy to be achieved.

PC-based software provides predefined configurations for time-saving setup and offers a powerful full drag-and-drop DSP, including AGC,
Ducker, various mixer types, delay, A.N.G (automatic gain control), ANR (acoustic noise reduction), PEQ, feedback, high/low pass, message player,
event scheduler for element adjustments, logic control, presets and event control, input/output streaming, network paging, VoIP and SIP
client, level control, recording, etc., making the whole system flexible and easy to program and integrate.

The Sinergia system is a fully digital public address/voice alarm system that meets all high levels of total redundancy and complete real-time monitoring for PA/VA installations, including automatic switch to redundant processor in case of main failure, 2 redundant AC networks, 48 V DC battery backup, our 3rd generation real-time audio network ATEÏS-Net with less than 1 ms latency in redundant loop or star-wired architecture, redundant paging, console loops, and A/B loudspeaker lines for each zone.

In accordance with EN 54-16 and UL 2572, the system, including power supply, amplifiers, PA microphones, and loudspeaker lines, is fully monitored with all faults reported and recorded. Multiple volume controllers can be installed on monitored loudspeaker lines without the need for inverted loop cable. Sinergia system also allows integration with third-party control via RS485 and Ethernet.
