This chapter describes how to use the Audio Panel to control ADAT Optical and AES-3id I/O.
If you did not install the software, do so now. For information on installing the software, read the release notes on the CD and the booklet enclosed with the CD.
You can use the Audio Panel program on your system to manage multiple audio inputs and outputs, and to control various audio settings. Refer to the Audio Panel Help menu for general information on using the Audio Panel.
 | Note: Software instructions included in this section are based on the IRIX 6.3, IRIX 6.4, and IRIX 6.5.x operating systems. If you upgraded to a subsequent operating system, some of the instructions may no longer be valid. If this is the case, check the latest information by using the online documentation that came with your new software. |
When a PCI Digital Audio Board is installed, you can use the Audio Panel to display the ADAT and AES device controls, set the default input and output to ADAT or AES I/O, and set the audio signal path to ADAT or AES I/O.
To display the ADAT and AES device controls:
Open Audio Panel:
From the Toolchest, choose Desktop > Control Audio.
Select the desired AES or ADAT device control panel from the view menu.
The selected device control panel appears, where you can adjust parameters such as sample rate, input source, and output destination. For details, refer to the Audio Panel Help menu.
If more than one PCI Digital Audio Board is installed, the system names each board using an incremental prefix naming scheme. For example, if two PCI Digital Audio Boards are installed in your system, one ADAT input is displayed as “RAD 1.ADAT In” and the other as “RAD 2. ADAT In.”
Audio Panel displays device controls for ADAT In, ADAT Out, AES In, and AES Out for each PCI Digital Audio Board installed in your system. You can designate any of these devices as a default, which means your system uses the device as the internal audio device unless otherwise specified by another application. To set the default input and output, simply open Audio Panel and use the Default menu to select a default input and output and device.
You can select either electrical or optical signal paths for the AES input and output devices. For ADAT input and output devices, you can select either the optical signal path or a disabled signal path (labeled “None”).
To set the input source with Audio Panel:
Position the cursor over the input device panel (if the device panel you need is not displayed, use the View menu), then hold down the right mouse button to display a menu that contains the Input Source option.
Choose the input source (for example, AES In or Optical In) that you want the input device to use. “AES In” is the electrical input.
Selecting the optical input for AES disables the ADAT input, since the two devices share the same optical connector. Similarly, selecting the optical input for ADAT automatically switches the AES input to the coaxial digital electrical connector.
To set the output destination with Audio Panel:
Position the cursor over the output device panel (if the device panel you need is not displayed, use the View menu), then hold down the right mouse button to display a menu that contains the Output Destination option.
Choose the output destination (for example, AES Out or Optical Out) that you want the output device to use. “AES Out” is the coaxial digital electrical output.
Selecting the optical output for AES disables the ADAT output, since the two devices share the same optical connector. Similarly, selecting the optical output for ADAT automatically switches the AES output to the coaxial digital electrical connector.
