    4. Configure your digital recording software. (see your software manual) About the DMAN The DMAN is a full-featured, yet low-cost digital audio card with a built-in MPU401 interface and a header for an optional wavetable synthesis daughterboard. The DMAN features 16-bit stereo sampling at various frequencies from 5.53 to 48 kHz, full-...

  • Page 7: About Plug-And-Play

    About Plug-and-Play The PC ISA bus architecture requires allocation of memory and I/O address spaces, DMA channels, and interrupt request (IRQ) lines among all peripherals, yet there are no defined hardware or software mechanisms for allocating these resources. As a result, configuration of ISA cards is typically done with DIP switches and jumpers that change the decode maps for memory and I/O space and steer the DMA and IRQ signals to different pins on the...

  • Page 8: Pnp Theory Of Operation

    PnP Theory of Operation Think of PnP as digital aspirin. Device configuration occurs transparently in an all-PnP environment. At bootup, the BIOS and the operating system detect changes and attempt to allocate resources, eliminating the need to manually configure resources such as IRQ lines, DMA channels, I/O ports and memory space.

  • Page 9: Digital Recording Dos And Don'ts

    DMAN, the only way to make a noisy digital recording is to add the noise yourself! Digital Recording Dos and Don’ts Meters are not meant to ever go into the red. Digital recording is very unforgiving of clipping. Unlike analog systems, where tape saturation gives a nice smooth compression, digital distortion sounds like someone is breaking a pane of glass in your ear.

  • Page 43: Troubleshooting

    Troubleshooting This section addresses potential problems that can occur in all operating system environments, with emphasis on hardware troubleshooting. Within the PC environment there is a limited number of hardware resources (addresses, IRQs, and DMA channels) available for use. Since audio cards require many resources, most audio card installation problems arise from improperly set IRQ and DMA values.
  • Page 44 If this problem occurs in Windows, open the driver configuration dialog box and set the IRQ to match the current DMAN setting. If this problem is in DOS, reconfigure the IRQ in the DOS application itself to match that of DMAN.
