“Audio Out” block, then select the DAO block. Right-clicking the DAO block and selecting Device
Properties produces the DAO Properties dialog.
• Audio Data Format - I
• Output Sampling Frequency Range - Select the Fs range where 1FS = 32 kHz, 44.1 kHz, or 48 kHz,
• SPDIF Enable - Checking this box configures DAO for S/PDIF output rather than I
2Fs = 64 kHz, 88.2 kHz, 96 kHz, 4FS= 128 kHz, 176.4 kHz, 192 kHz, etc.
