    The DS8000 is a 2U, 8 input to 32 output mic/line distribution system with 16 transformer balanced isolated outputs, and 16 electronically balanced outputs fitted as standard. Input transformers can be ordered as an option, as can the replacement of the electronically balanced outputs with transformer balanced outputs.

    (electrically) isolated. Front panel outputs are transformer balanced and so are isolated. External Supply This socket must only be used to connect directly to another DS8000 and NOT as an input from a separate supply. Attempting to connect another supply to this socket will damage the unit and invalidate the warranty.

  • Page 18: Aes Digital Output Options

    AES option PCB. These are: Internal or External wordclock The DS8000 can either generate the clock for the AES digital outputs using its own internal clock, with adjustable sample rate (48k/96k/192k), or be synchronised via an external clock on the BNC connector.

  • Page 19: Permissive Clock Mode

    (so 48/96/192) — this is known as permissive mode and is explained below. Permissive Clock Mode When sync is set to external, the DS8000 will only lock to an external wordclock if it falls within close tolerance of a standard professional sample rate — so 48kHz, 96kHz or 192kHz, +5%.

  • Page 20: Internal Sample Rate

    Page 20 Internal Sample Rate When sync is set to internal, the DS8000 will operate the AES digital outputs at one of three professional rates — 48kHz, 96kHz or 192kHz. The unit’s analogue bandwidth extends beyond the typical Nyquist point for 48kHz digital systems, ensuring that the higher sample rates’...

    A typical scenario where the ground link might be required would be if the device receiving a wordclock from the DS8000 (or supplying a wordclock sync signal to the DS8000) has an external DC supply or is USB powered from a laptop running on battery power — a high-end...
  • Page 22 B4 (Chs 7&8) B4 (Chs 7&8) B4 (Chs 7&8) The DS8000’s digital outputs utilise industry standard drivers and circuitry to ensure that the performance of the digital outputs is as widely compatible as possible with other professional equipment. The pairs of outputs will drive into 110R standard loads, tested up to cable distances of 100 metres.
  • Page 23 Warranty Your DS8000 is guaranteed for a period of five (5) years from the date of purchase. We hope that it gives you many more years of reliable service than this but, should anything go wrong, please contact us to advise you about repairs or any spares you might require.

  • Page 26 DS8000 Operator’s Manual Page 26 Appendix I: Appendix I: Appendix I: Appendix I: All about splitters A splitter, or distribution system, is responsible for providing multiple feeds from a single audio source to enable different processing devices to share the same input signal. In this way a signal is split and distributed to multiple destinations.

  • Page 28 DS8000 Operator’s Manual Page 28 Passive Splitter with Transformer Isolation This second system uses a passive splitter again, so no amplification on stage, but does utilise transformers to allow the grounds to be isolated from each other. The input is connected to one side, the primary, of the transformer, and multiple secondaries provide isolated outputs for each feed.
  • Page 29 OB Truck will not introduce grounding problems. As the DS8000 is an active device, it can generate the 48V phantom power required for the microphone inputs if required. It also senses 48V being switched in from a mixing desk and can enable the respective input’s 48V supply if needed, providing seamless “echoing”...
