Артикул: RTU 120/1
Оформить заказRTU 120/1 is used as part of digital public address and public address communication systems where one audio distribution line must be connected to the facility IP infrastructure.
The model is suitable for small and medium-sized sound coverage zones: administrative premises, corridors, technical areas, retail spaces, educational buildings, healthcare facilities, warehouse areas, and production rooms with moderate acoustic load.
The single-channel architecture makes system design straightforward: one amplifier corresponds to one broadcast zone. This is convenient for facilities where individual loudspeaker addressing is not required, but centralized control of the entire zone through the InterTech Communication system is important.
RTU 120/1 is especially useful in modernization projects. If analog loudspeakers and cable lines are already installed at the facility, the amplifier helps retain the existing acoustic infrastructure and integrate it into a digital control system with scheduled messages, live announcements, priorities, alert scenarios, and centralized monitoring.
Within the full InterTech Communication ecosystem, the amplifier can operate together with the IS-R server, Dispatcher Workstation, IP loudspeakers, intercom devices, voice notification scenarios, and centralized monitoring tools.

RTU 120/1 allows one loudspeaker line to be connected to a digital public address system and managed through the facility IP infrastructure.
The amplifier helps use already installed analog loudspeakers and cable lines if they meet project requirements. This reduces dismantling work, accelerates implementation, and enables a gradual transition to a digital architecture.
When integrated with the IS-R server and Dispatcher Workstation, the amplifier becomes a managed system element. The operator can start broadcasts, select zones, apply message priorities, and include the line in common alert scenarios.
As part of the InterTech Communication system, the amplifier can be used to transmit pre-recorded messages, live operator announcements, background music, process notifications, and emergency voice messages.
