Pyxis - Compact Multi-Format Router

Feature Rich Routing for Small and Medium Size Applications

Pyxis features a wide range of signal cards in a choice of a 1 RU or 3 RU frame. All cards are removable from the front allowing ease of maintenance and removing the need for the router to be de-cabled should servicing be required. Both frames can be configured with dual redundant power supplies, and signal cards are available for all common broadcast formats: 1080p 3 Gb/s, HD-SDI, SDI/ASI, analog audio, AES audio and RS-422. The SDI cards are also suitable for routing a wide range of telco signals (STM-1, STM-4, T4, E4).

FEATURES

  • Flexible multiformat, multilevel router range
  • High packing density with 172 HD-SDI in 1 RU up to 722 HD-SDI in 3 RU
  • Up to 1442 stereo AES and analog audio in 3 RU or 362 in 1 RU
  • 3 Gb/s capability on all HD-SDI routers
  • Mix and match all common broadcast signal types: 3 Gb/s, HD-SDI, SD/ASI in 722, 342, 172 sizes. AES, stereo analog audio in 1442, 1082, 722, 362 sizes. Mixed analog, AES and MADI I/O up to 2722
  • Dual redundant PSUs
  • All active parts removable from the front for ease of maintenance
  • Integral control system with dual redundant control option in 3 RU frame
  • Integrated audio converters allowing mix and match of AES and analog audio in the same frame
  • 342 HD-SDI and four levels of 362 audio in a single 3 RU frame
