IP Amplifier 4or8CH
The cornerstone of the Public Address (PA) System implementation is represented by this state-of-the-art IP power amplifier. Output power across channels is dynamically allocated based on connected speaker requirements, with performance being optimised within the amplifier's total power budget. Connection to the central exchange is established via standard Ethernet infrastructure (CAT5/CAT6) or fibre optic cabling, through which reliable digital signal transmission is ensured.
Class D amplification technology has been selected for its exceptional efficiency, significantly reduced power consumption, and extended operationallifespan — factors considered critical for infrastructure deployments in various markets’ demanding environments. This network-based solution has been specifically engineered for challenging settings such as tunnels, transportation hubs, industrial facilities, educational institutions, healthcare environments and underground transit systems where acoustic conditions are challenging and system reliability is paramount.

Flexible collocation :
Independent amplifier channels; integrated standby channels can be enabled
automatically in the event of channel failure;
Primary and standby redundancy:
when the IP amplifier plays audio sources, the standby channel can replace any damaged audio channel at any time, whichever fault occurs first.
When the damaged audio channel is restored, the alternate channel can replace another damaged channel.
