7. Using The XL48
To avoid electrical shock, never operate the equipment with the covers removed.
Do not operate the equipment or any of its parts if safety guards are ineffective or
their effectiveness has been reduced.
When the unit is first powered up it will be set to 96 kHz using the internal clock
(factory default setting). When a change is made to the sample rate and clock
setting it will remain stored during a power cycle. For example, if you always
want the unit set at 48 kHz and using an external clock source, you don’t have set
up these options each time the unit is power cycled.
