SDT 501 ARK-DAB
Compact, flexible and easy to use the SDT ARK-DAB transmitters features a built-in SFN adapter and very advanced SWDT® (Software Defined Transmitters) technology, typical of this series of products.
The SWDT® technology allows selecting parameters in various ways: remotely, using a clean contact; via SNMP commands; via TCP/IP, using the Web graphic interface.
An innovative firmware allows zero error signal processing thanks to an internal 32 bit architecture.
Functional interfaces are available for total remote control of the apparatus by means of serial protocols or TCP/IP ports. Thanks to the internal Web server the apparatus can be easily monitored and configured using a LAN connection and a standard Web browser.
Moreover, the built-in SNMPv2 server allows performing all types of automated remote control.
The high reliability of the transmitter family makes it ideal for basic broadcasting coverage in urban and metropolitan areas, for example.
Scalable and flexible system configuration permit Various redundancy concepts such as dual drive, passive standby or N+1 can be implemented to maximize availability.
