ADAT Mode (Windows Only) Sets ADAT I/O to ADAT or S/MUX Mode
When recording or playing back at 44.1 kHz or 48 kHz, the ADAT I/O on
the AudioBox 1818VSL will provide 8 audio channels over the optical
inputs and outputs. When recording or playing back at 88.2 kHz or 96 kHz,
these connections will provide 4 audio channels.
In order to record or playback at 88.2 kHz or 96 kHz over
ADAT, you must set the correct Input and Output ADAT
Modes. AudioBox VSL provides two modes:
ADAT 8x8: Channels 1-8 (44.1/48 kHz)
ADAT SMUX 4x4: Channels 1-4 (88.2/96 kHz)
If you are recording at 88.2 kHz or 96 kHz, you must set the ADAT In Mode
to “ADAT SMUX 4x4” in addition to setting the correct sample rate.
If you are outputting audio through the optical outputs
on your AudioBox 1818VSL at 88.2 kHz or 96 kHz, you
must set the ADAT Out Mode to “ADAT SMUX 4x4” .
By default, these Modes are set to ADAT 8x8. As long
as you are using your AudioBox 1818VSL at 44.1 kHz or
48 kHz, you do not need to make any changes.
Power User Tip: Failure to set the correct ADAT Mode for the sample rate being used will result in audio
artifacts. Setting ADAT mode is not necessary when using Analog or S/PDIF I/O at higher sample rates.
ADAT Mode (OS X Only) Sets ADAT I/O to ADAT or S/MUX Mode
When recording or playing back at 44.1 kHz or 48 kHz, the ADAT I/O
on the AudioBox 1818VSL will provide 8 audio channels over the
optical inputs and outputs. When recording or playing back at 88.2
kHz or 96 kHz, these connections will provide 4 audio channels.
In order to record or playback at 88.2 kHz or 96 kHz over ADAT,
you must set the correct Input and Output ADAT Modes. These
settings are available in OS X’s Audio MIDI Setup Utility.
By default, these Modes are set to 18ch-24bit. As long
as you are using your AudioBox 1818VSL at 44.1 kHz or
48 kHz, you do not need to make any changes.
To record or playback at 88.2 kHz or 96 kHz, open the Audio MIDI Setup
Utility on your Mac (Applications/Utilities/Audio MIDI Setup).
Once Audio MIDI Setup opens, click on the Audio window. If the Audio
window doesn’t open when Audio MIDI Setup first opens, go to Window
and select “Show Audio window.”
Select “AudioBox 1818VSL” from the audio device list on the left. To the
left of the Sample Rate selection menu, you will find the ADAT Mode
menu:
18ch -24bit: Channels 1-8 (44.1/48 kHz)
14ch - 24bit: Channels 1-4 (88.2/96 kHz)
