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 APTs 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 audio trans- mission 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.Main Features:Low Latency – Low Costs: With SureStreams capability for re- dundant streaming, broadcasters can elevate more cost-effective but imperfect services into genuine low-latency, broadcast-grade IP connections.Single Port and VLAN Configurations: As a VLAN-aware device, the IP Silver MPX can leverage multiple networks as SureStream paths. When using SureStream on a single network, the statistical diversity generator emulates the desired diversity across component streams.Scalability and Flexibility: SureStream stands as the most flexible and scalable solution for safeguarding content transmission. It inte- grates paths from diverse networks, including MPLS, satellite, mi- crowave, and cellular (4G/5G), to forge a unified and highly robust connection.Control Over Target Latency: The NTP-based Content Alignment feature eliminates variable latencies of an IP network within narrow limits. For program transmissions in multi-frequency networks (MFN), this ensures a seamless program transition between frequencies.Stable Latency: The timestamp-based transmission requires only a single setting on the IP Silver Encoder to define the general target latency to each Decoder at the transmitter sites.Fine Adjustment of the Program Playout: Fine-tuning is essential for the optimal alignment of program overlaps in the MFN transmitter network. The IP Silver Decoder offers the flexibility for individual la- tency adjustments at the transmitter level, down to millisecond steps.Signal Transperancy: Offers the highest signal transparency and does not affect the watermarking (e.g., Nielsen).Low Delay: The coding delay that lasts only a few milliseconds pro- vides a performance that is comparable to that of the linear PCM processing.Non-Framed: APTmpX is a non-framed algorithm. Each data packet is decoded in-dependently from previous packets. If a packet is lost, the next packet is decoded immediately (no packet-group depen- dency, no frames).Simplex composite/MPX transmissionSerial AUX Data in Duplex CommunicationProfessional composite/MPX formats, APTmpX and linear @192/128kHz FSSupports RTP/UDP streamingPoint-to-Point and Point-to-Multipoint operationPacket redundancy, provided by SureStream enables reliable transmissions on any networkForwarding and protecting of UDP Streams, such as EDI or E2X dataNTP-based packet timestamping allows to set target latencies per streamSupports UPnP IGD protocol for configuration of UPnP enabled gateways (routers)The advanced NAT traversal capability overcomes port blockages in the networkSupports Diffserv Quality of Service (QoS) on variable DSCP valuesVLANs and virtual IP interfaces enables multi-network integrationPerformance monitoring on each individual IP streamConfigurable jitter buffer for receiving IP stream (1ms to 5000ms)Specifications:Analog MPX I/O: Unbalanced, capacitive isolated BNC connectors for Input/Loop and OutputsInput/Output Clip Level: Input MPX Encoder +10 to 16dBu Output MPX Decoder +10 to 16dBu level adjustment in 0.025dBu stepsMPX Bandwidths: 53kHz to 88kHz, compressed and linearMPX Formats: APTmpX 300/400/600kbps (53kHz) APTmpX 900kbps (64kHz incl.
