Description

APT ­IP CODEC

 

The APT IP CODEC (formerly known as WorldCast Horizon NextGen) offers the most complete set of IP features ever included in APT’s extensive range and features both our revolutionary “SureStream” technology and intelligent ScriptEasy scripting. In addition, this next generation IP audio codec also offers a wide range of algorithms as standard on a solid DSP platform with dual IP ports and redundant power supplies. Despite the high feature density, the APT IP CODEC is extremely competitively priced.

Perfect for STLs and mission-critical applications, the APT IP CODEC provides extensive control and monitoring capabilities to manage both your audio, data and network conditions and other equipment located at the transmitter site.
