    R-BUS output, and consequently to the Roland Multitrack. 5. Setting the Roland tracks to “record ready” will allow us to monitor the Delta R-BUS signal at the Roland inputs. The signal at the Roland inputs will show up at the Roland outputs, and consequently at the Delta R-BUS inputs.
  • Page 39 We have 8-busses in our digital mixer, and the R-BUS connection on the Delta R-BUS PCI Audio Card is capable of eight audio input and output streams. The guitar and bass will take up two of these streams, so we have six left for the drums (we could have used just six mics, but we’re not...
  • Page 40 H/W Out 1/2 (the leftmost column), select H/W In 1/2 as the source. Doing so will allow you to monitor the digital mixer’s buss out 1 and 2 through the Delta R-BUS hardware inputs, and back to the digital mixer’s tape returns. On H/W Out 3/4 select H/W In 3/4 as the source, set H/W Out 5/6 to H/W In 5/6, and set H/W Out 7/8 to H/W In 7/8 as their monitoring sources.
  • Page 41 See Appendix C for more information on this, and other choices you may have for synchronizing the Delta R-BUS with your digital mixer. We suggest that you use the Delta R-BUS’s Wordclock output on the breakout cable to send clock to the digital mixer (if it has wordclock input), and set the external sync in the digital mixer to receive its clock from the wordclock input.
  • Page 42 -- you may even choose to turn your computer off before making the connections. In this example, we will connect a DAT to the Delta R-BUS’s breakout cable using coaxial S/PDIF cables (75-ohm impedance RCA-to-RCA). We’ll also connect the Delta R-BUS’s analog outputs to a sound system for monitoring...
  • Page 43 3. Because you will be recording from the S/PDIF input, you will need to set up the Delta R-BUS to synchronize its master clock with the S/PDIF input. To do this, open the Hardware Settings page of the control panel software.

    (or software acting as “virtual” hardware) in the system. The Delta R-BUS has been carefully designed to minimize the number of resources consumed (it requires just one IRQ and does not require any DMA channel resources).
  • Page 54 One of the quickest ways to change the resources assigned to a PCI card like the Delta R-BUS is to merely relocate the card to another PCI slot. With the computer’s power off, remove the Delta R-BUS from its current PCI slot, move it to another available PCI slot, and turn your computer back on.

  • Page 56 IRQ for each PCI slot on the motherboard. This may be very handy in resolving IRQ assignments for PCI devices. Also, sometimes a BIOS is configured to direct a particular IRQ to an ISA legacy device (non-PnP ISA card), and needs to be told to look for a PCI/ISA PnP device (some systems default to this, especially with IRQs 3 and 4).
