  • Page 7: Introduction

    The Sirius 600 audio input and output cards provide the necessary conversion to enable stereo analogue sources or destinations to be routed through any Sirius 600 digital crosspoint card, and to be used in combination with the Sirius 600 AES digital audio cards. •...

  • Page 9: Hybrid Audio Cards

    These are converted to digital signals of an internal format designed to feed Sirius 600 AES or Audio Hybrid output cards via any Sirius 600 digital crosspoint. If the frame is supplied with a valid AES11reference, which can be in the range 32 to 54 kHz, all digital outputs from the card are aligned to the reference.

  • Page 14: 4795 Output Card

    These are converted from digital signals of an internal format produced from either an AES or Audio Hybrid input card via any Sirius 600 digital crosspoint. If the frame is supplied with a valid AES11reference, which can be in the range 32 to 54 kHz, the card looks for synchronous digital signals, which allows all audio modify functions to be available.

  • Page 16: 4796 Output Card

    These are converted from digital signals of an internal format produced from either an AES or Audio Hybrid input card via any Sirius 600 digital crosspoint (the card auto-detects whether the signal is synchronous or asynchronous and converts either).

  • Page 17: Adjusting The Gain

    The different input and output modes are configured in the Sirius 600 configurable database, see Section 7 of the main Sirius 600 user guide, no audio modification is available with the fixed database. Each input and output may either have its mode fixed in the database, or be switched dynamically from a 6276 or 6277 control panel.
  • Page 18 Although it may appear that audio is being modified independently by the input and output cards, all processing is actually performed by the output card in the digital domain, according to data received from the Sirius 600 control card. Issue 3 Rev 2 Page 18 ©...
