Connecting Your Studio
This chapter provides general information on
connecting Pro Tools to your system, including
digital equipment, effects units, MIDI gear, and
SMPTE synchronization devices.
Refer to the 888|24 I/O Guide, the 882|20 I/O
Guide, the 1622 I/O Guide, or the ADAT
Bridge I/O Guide for specific details regarding:
• Front and back panel connectors and indica-
tors
•Technical specifications
Setting Up Your Studio
The following diagrams provide general sugges-
tions for connecting studio gear to your system.
Figure 1 illustrates a typical studio setup, with
an 888|24 I/O connected to a mixing console,
effects and other equipment.
Figure 2 illustrates a setup without a mixer,
where effects and monitoring gear are con-
nected directly to an 882|20 I/O.
The 888|24 I/O analog audio connectors
are balanced XLRs with pin 2 wired hot
(or “+”), pin 3 cold (or “–”), and pin 1
ground.
If you are connecting a balanced system, pin
1 and shield should be connected at the in-
put only (not at the output). This will pre-
vent ground loops between the shield and
pin 1 conductor.
If you are connecting an unbalanced signal
to the 888|24 I/O inputs or outputs, connect
only pin 2 to the “+” signal, and pins 1 and
3 to ground at all inputs only.
