Adding or Removing I/O Cards
The 192 I/O comes with one available expan-
sion bay on the rear of the unit. This bay lets
you add another 192 AD Card, 192 DA Card, or
192 Digital Card (all sold separately) to increase
the amount of available I/O on the unit.
The expansion bay is the only bay that allows
for another card. The other three bays are hard-
wired for the appropriate card (the upper left
bay houses a 192 AD card; the upper right, the
192 Digital Card; and the lower left, the 192 DA
card). See “Installing an I/O Card” on page 27.
These factory-installed cards can be removed, if
needed, for servicing, or to swap out cards in the
fourth bay for different studio setups. If you re-
move a single default card from the 192 I/O, the
unit will continue to function while the audio
card is being serviced. See “Removing an
I/O Card” on page 30.

your HD system.

grounded.

lose the screws—put them in a safe place!
