​​SX-2000 Series 

Network enabled system ideal for installations in large building complexes.

The SX-2000 is a scalable system for configuring versatile and highly effective PA systems. The system features new matrix capabilities, so that a single system can have its components distributed in different locations under centralized control.

Ideal for large scale installations ranging from multiple buildings to local systems, the versatile SX-2000 Series is particularly suitable for using in airports and railway stations, factories, shopping malls and large offices. The system‘s versatility such as dual power source and redundancy for fail-safe operation makes it a reliable solution for any specific installation without long lead times and the expense of custom systems.

Application examples:

N-8000 Series

A highly reliable system assuring higher levels of security, versatility and sound quality.


TOA’s unique N-8000 IP intercom System is an integrated audio communication system that employs packet audio technology over the iP network to achieve fast, accurate communications with optimal security and reliability. Applications range from conversation, paging broadcasting and BGM broadcasting to emergency paging and broadcasting, audio triggering and other security functions.

Users can select between two communication modes according to their needs: Master-to-Master station communication for duplex conversation at factories, hospitals and various other facilities; or Master-to-Sub station communication for use by institutions such as schools or prisons. The system frequency response extends to 7 kHz, enabling reliable transmission of a full range of emergency communications, including clear, easily understandable PA announcements.

VX-3000 Series

Combined highly integrated voice alarm and public address system.

Security is an important issue more than ever. TOA's VX-3000 is a reliable and energy-saving voice alarm system certified on the European Standard EN 54-16. It combines many functions for PA/VA applications in one unit frame. The low number of system components makes the design and installation easy, saving space and reducing cable complexity. This enables a rapid system configuration reducing the assembling cost. Three different frames with different output types and modular class D amplifiers with three different power ratings make the system flexible and allow for a configuration matching exactly with the user’s requirements. Furthermore, it succeeds with its energy efficiency and low operating costs, by using low loss class-D amplifiers and modern power supply technology. Thanks to its flexible and scalable system architecture the VX-3000 system can be used for both small and large applications, with up to 1280 remote microphones, 1920 audio sources, 1024 internal messages and 2560 speaker lines. The system can be installed both centralised as well as decentralised, while latter setup drastically reduces cabling costs. Different Ethernet switches provide a redundant network and a maximum distance between parts of the VA system of 30 km. 

Thus, the advanced user level enables the end-user to set the built-in timer (since version 5) and change audio files for general broadcasts, such as pause chimes in schools and factories, or general or advertisement announcements in shopping areas. With an optional operation software the user can easily control the PA functions by a computer.
