  • Page 20: Clock Source Selection

    If you use an analog (or digital) mixer that is connected to both the inputs and the outputs of the DSP24 ADAT card, you can monitor via the mixer so that is no problem. The DSP24 hardware however has a built-in digital mixer so you do not really need an external mixing desk.
  • Page 21 ST A DSP24 ADAT UDIO ADAT Select this clock source when the device connected to the optical ADAT input should supply the clock / samplerate for the DSP24 ADAT card. S/PDIF Select this clock source when you want to record from the S/PDIF input with the clock supplied by the device connected to the coaxial digital input of the card.

  • Page 22: Mixer Controls

    These functions are represented by an AC-97 codec chip that is on your DSP24 ADAT card. AC-97 has been defined as standard by Intel for consumer audio applications on modern PCs. The AC-97 codec ST Audio is using works with a 18bit ADC, a 18bit DAC and an analog mixer.

    UDIO IX. Usage with software applications For each application you are using with the DSP24 ADAT you have to follow some configuration steps. Basically, every stereo input or output channel of the card can be used like a normal soundcard using the corresponding devices. Normally every program will have a configuration function where you can select the devices.
