192 I/O Guide
8
The External Clock In port is configured by your
choice for Clock Source in the Hardware Setup
dialog. The External Clock Out is configured us-
ing the External Clock Out selector in the Hard-
ware Setup dialog.
AC Power
This connector accepts a standard AC power ca-
ble. The 192 I/O is auto power-selecting (100V
to 240V) and will automatically work with a
standard modular cable to connect to AC power
receptacles in any country.
Primary DigiLink
The Primary port is where the DigiLink cable
connects from your HD Core or Process card to
the 192 I/O. The Primary DigiLink port sends
and receives all 32 I/O channels to and from the
HD Core or Process card. As the 192 I/O is a 16-
channel only device, channels 17–32 are passed
through to the Expansion or Legacy port.
Expansion DigiLink
The Expansion port is where the DigiLink cable
connects an additional 192 I/O or 96 I/O to
your base, or primary, 192 I/O. This port passes
channels 17–32 to the secondary, or expansion,
I/O.
Legacy Port
This port is used to connect MIX-series Digide-
sign audio interfaces to 192 I/O. You can con-
nect two eight-channel interfaces (such as the
888|24 or 882|20) or a single sixteen-channel in-
terface (1622 I/O, 24-bit ADAT Bridge I/O, or the
original ADAT Bridge I/O) for expanded input
and output options, using their original cables.
When the Legacy port has been activated from
within Pro Tools, your MIX-series I/O will ap-
pear as channels 17–32 in the Pro Tools mixer.
To connect HD or Legacy audio interfaces, refer
to the
Getting Started With HD Guide
.
Legacy and Expansion Peripheral Port
Limitations
Because both the Legacy port and the Expansion
port use channels 17–32, you can only use one
at a time.
To select the Legacy or Expansion ports, refer to
the
Pro Tools Reference Guide
.
The Legacy port is not available in any session in
which the sample rate is set for higher than
48 kHz.
Accessory Port
This port is not supported at this time.
Because crucial timing data is passed
through the Loop Sync and Word Clock ports,
you should use high-quality, 75-ohm RG–59
cables for making connections.
