192 Digital I/O Audio Interface
• Supports sample rates up to 192 kHz. (At least
one 192 I/O or 192 Digital I/O must be con-
nected to your Pro Tools|HD system for 192 kHz
recording, processing, and playback.)
• Supports digital connections, including
AES/EBU, S/PDIF, TDIF, and ADAT Optical:
• Digital (2 Digital I/O Cards): 16 channels,
DB-25 (AES/EBU and TDIF), or two pairs of
Lightpipe (ADAT Optical) connectors.
• Digital (Enclosure): two channels, XLR
(AES/EBU) connectors; two channels RCA
(S/PDIF) connectors.
• Optical (Enclosure): eight channels, one
pair of Lightpipe (ADAT Optical) connec-
tors (selectable to two channels, S/PDIF).
•Word Clock in and out receive or send 1x
Word clock (configurable to 256x for Leg-
acy support, see “Optional Legacy I/O Au-
dio Interfaces” on page 3).
96 I/O Audio Interface
• Supports sample rates up to 96 kHz.
• Supports analog and digital connections, in-
cluding AES/EBU, S/PDIF, and ADAT optical:
• Analog: eight channels, 1/4-inch TRS (bal-
anced or unbalanced) connectors, +4 dBu
or –10 dBV
• Digital: two channels, XLR (AES/EBU) con-
nectors; two channels, RCA (S/PDIF) con-
nectors
• Optical: eight channels, one pair of Light-
pipe (ADAT Optical) connectors (switch-
able to two channels, S/PDIF)
•Word Clock in and out receive or send 1x
Word clock (configurable to 256x for Leg-
acy support, see “Optional Legacy I/O Au-
dio Interfaces” on page 3)
96i I/O Audio Interface
◆
Supports sample rates up to 96 kHz.
• 16 discrete channels of input, and two chan-
nels of output, with 4-segment LED meters on
each channel. Audio inputs and outputs in-
clude:
• 16 channels of 24-bit, 96-kHz capable ana-
log input, with adjustable input sensitivity
•Two channels of 24-bit, 96-kHz capable an-
alog output, with selectable operating level
•Two channels of 24-bit, 96 kHz-capable
digital S/PDIF RCA input and output
• Loop Sync In and Out
• External Clock In and Out
• Expansion DigiLink port
Optional Legacy I/O Audio Interfaces
For additional input and output channels, older
Digidesign audio interfaces (or
Legacy I/Os
) can
be connected to the 192 I/O, 192 Digital I/O, or
96 I/O (the 96i I/O does not support Legacy in-
terfaces). Legacy interfaces can only be used
with 44.1 kHz or 48 kHz sessions. These include:
888|24 I/O Audio Interface
• Analog: eight channels, XLR (balanced or un-
balanced) connectors, selectable between
+4 dBu or –10 dBV
• Digital: eight channels, XLR (AES/EBU) con-
nectors; two channels, RCA (S/PDIF) connectors
882|20 I/O Audio Interface
• Analog: eight channels, 1/4-inch TRS (bal-
anced or unbalanced) connectors, selectable be-
tween +4 dBu and –10 dBV
• Digital: two channels, RCA (S/PDIF) connec-
tors
