APT IP streamers, known for their advanced analog audio encoding and decoding capabilities, are now available in MPX versions. The transmission of analog composite/MPX for FM transmitter supply, including the innovative compressed APTmpX format, features such as APT's proven SureStream technology for IP redundancy, and the distributed intelligence of ScriptEasy make the APT Silver Range stand out. With a focus on quality and affordability, the APT IP Silver Range ensures reliable and time-controlled IP MPX transmission at a high level. Designed for reliability, the IP Silver MPX is ideal for individual MPX FM feeds and multi-frequency transmissions. Optimized for Composite/MPX transmissions, this solution offers a wide range of wired network connectivity options and explicitly supports using 4G/5G modems for connectivity. With the low bitrates of the APTmpX, cellular networks have become viable options. Choosing the APT IP Silver MPX Encoder and Decoder means investing in the rock-solid performance that has made APT a trusted name for broadcasters worldwide.
APT IP Silver MPX:
| Models | MPX Formats | Analog Formats | Power Consumption | Main Power Supply | Height |
|---|---|---|---|---|---|
APT IP Silver MPX |
| Analog MPX Inputs or Outputs | 5W | 12 VDC, external PSU, wall-mount 100-264 VAC / 50-60 Hz | 1U |
The APT IP Silver Range is rich in network capabilities, featuring VLAN tagging and sophisticated NAT traversal techniques to accommodate networks with dynamic IP addresses, like the Internet or cellular connections. Additionally, its SureStream technology mitigates packet loss, while NTP-based time alignment minimizes latency fluctuations.

APTmpX is the industry’s leading composite/MPX compression algorithm, delivering exceptional audio transparency over low-bitrate IP connections. With bandwidth options as low as 300, 400, and 600, it removes the usual trade-off between audio quality and transmission efficiency. APTmpX eliminates the two main barriers to FM MPX migration - high bandwidth requirements and audio degradation - making it the go-to solution for cost-effective, high-fidelity MPX-over-IP transport.
Available on all APT codecs, SureStream ensures perfect audio or MPX delivery over IP by sending multiple stream copies across diverse network paths. Its intelligent redundancy engine reconstructs a flawless, low-latency stream at the receiver end - eliminating dropouts and ensuring true broadcast-grade reliability, even over imperfect networks.
