If you are recording at 88.2 kHz or 96 kHz, you must set the ADAT Input
Mode to “14ch -24bit” 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 Output Mode to
“14ch - 24bit” .
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.
Clock Source Select
(Windows Only)
Changes the Clock Source for the AudioBox 1818VSL.
The clock-source setting determines the port from which the AudioBox
1818VSL is receiving word clock information. This keeps the AudioBox in
sync with other digital devices. You can choose between Internal, S/PDIF,
or ADAT.
In general, you will want the AudioBox 1818VSL to be your
master clock, in which case you should set the clock to “Internal”.
This setting also means that your AudioBox is generating word
clock and sending this information out of its digital outputs.
If you want the AudioBox to receive sync from an external device,
choose the digital input to which the external device is connected
(S/PDIF or ADAT). The AudioBox 1818VSL’s sync light will flash from
blue to red. When the AudioBox is in sync, the light will be blue.
Power User Tip: When slaved to an external clock, the AudioBox 1818VSL will not
automatically change its sample rate to match the external clock. As a result, it may fail to
sync to the clock source. If your AudioBox is not syncing to an external source, make sure that
both your master device and the AudioBox 1818VSL are set to the same sample rate.
Setting Clock Source
(OS X)
Using Audio MIDI Setup to Set the Clock Source for the AudioBox 1818VSL.
The clock-source setting determines the port from which
the AudioBox 1818VSL is receiving word clock information.
This keeps the AudioBox in sync with other digital devices.
You can choose between Internal, S/PDIF, or ADAT.
In general, you will want the AudioBox 1818VSL to be your
master clock, in which case you should set the clock to “Internal.”
This setting also means that your AudioBox is generating word
clock and sending this information out of its digital outputs.
If you want the AudioBox to receive sync from an external
device, 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.”
