003 Family Setup Guide84
For stereo inputs, (such as a stereo keyboard or
the stereo output from a mixer), use an
odd/even pair of inputs. For example, connect
the left channel to Line/DI Input 1, and right
channel to Line/DI Input 2.
2 On the front panel, press the Input Channel
Select switch (located on the front panel) for
each corresponding input, making sure the
Line-DI switch is enabled (lit) for each channel.
3 Set your instrument’s volume to its optimal
level. For example, the optimal level for most
keyboards is between 80% and 100% of maxi-
mum volume.
4 When Pro Tools is launched and the input is
routed to a Pro Tools track, you can adjust the
input level with the Input Gain Control knob.
Connecting Equipment with
Digital Ins and Outs
Each 003 family interface provide up to ten dig-
ital inputs and outputs, including:
• Eight channels of ADAT Optical input and
output, or two channels of Optical S/PDIF in-
put. Digidesign recommends high-quality au-
dio grade optical cable for all optical
connections.
• Two channels of S/PDIF digital input and out-
put (RCA connectors).
Up to 18 channels of I/O can be achieved by us-
ing the S/PDIF RCA I/O, Optical (ADAT) I/O,
and analog I/O at the same time.

For line-level devices, the Input Gain Control

Only one S/PDIF input pair can be used at a
time. For example, if you use the optical in-
put for S/PDIF data, you cannot use the
RCA inputs. For more information on con-
figuring Digital I/O, see “Configuring
Pro Tools LE Software” on page 20.

“Digital I/O” on page 62

fects devices, see “Using External Effects

I/O, see “Recording from a Digital Device”
