OVERVIEW

The Intraplex® IP Link family of IP audio codecs provides high-end features at an affordable price.

Offering an array of audio coding options, the IP Link codecs are suitable for use in Studio to Transmitter Links (STLs) as well as audio contribution and distribution networks. Support for IP multicast and multiple unicast streams enables one encoder to feed multiple decoders.

By incorporating three IP Interfaces that can be used for streaming and management, the IP Link systems can provide a level of reliability not seen in comparably-priced codecs.

As the latest addition to the Intraplex family of audio transport products, the IP Link audio codecs bring legendary Intraplex reliability to the IP codec market.

Main Features of Intraplex® IP Link

  • IP Link 100: Single bi-directional stereo audio channels
  • IP Link 200: Two bi-directional stereo audio channels
  • Standard: Linear, AAC-LC, Opus and G.722 audio coding
  • Optional: AAC-HE, AAC-HEv2, AAC-ELD, MPEG2, MPEG3 and Enhanced aptX audio coding
  • Other transport modes: Transparent AES up to 192 kS/s to support composite FM multiplex signal over AES
  • Protocol Encapsulation: RTP, SHOUTcast/ICEcast, MPEG-TS
  • Three independent IP interfaces for redundant network operation
  • Optional redundant power supply
