Analog Outputs

TRS OUT 1 and 2

HD OMNI provides two 1/4-inch TRS Outputs
for monitoring either ANALOG OUT 1 and 2 or
ANALOG OUT 7 and 8 (or neither). This can be
set in Pro Tools on the Analog Out tab of the
Hardware Setup dialog (see “Analog Out” on
page 28) or
on HD OMNI in SETUP mode (see
“TRS Output Mirrors (TRSOUT)” on page 47)

ANALOG OUT 1–8

HD OMNI provides a DB-25 connector for eight
channels of analog audio output. These bal-
anced outputs operate at +10 dBu (Speaker level)
or at +24 dBu (Line level). You can set the out-
put level in Pro Tools on the Analog Out page of
the Hardware Setup dialog (see “Analog Out” on
page 28).

Digital Inputs and Outputs

AES EBU OUT 1–8

HD OMNI provides one DB–25 connector for
eight channels of AES/EBU output. Each of the
paired channels is a balanced three-conductor
signal, and supports 192 kHz sample rates in
Single Wire mode.

AES/EBU INPUT

HD OMNI provides a single stereo AES/EBU
(XLR) input. The AES/EBU Input supports sam-
ple rates up to 192 kHz using AES Single Wire.

S/PDIF IN and OUT (Coaxial)

HD OMNI provides RCA jacks for stereo S/PDIF
digital data stream input and output. S/PDIF
supports up to 24-bit audio, at sample rates up
to 192 kHz.

Back panel analog TRS outputs, and analog and digital
(AES/EBU) DB-25 outputs

For a pinout diagram for the analog DB-25
connector, see Appendix A, “Pinout Dia-
grams for the DB-25 Connectors.”

Back panel digital inputs and outputs

For a pinout diagram for the AES/EBU DB-
25 connector, see Appendix A, “Pinout Dia-
grams for the DB-25 Connectors.”

To maintain data integrity and minimize
jitter, use only 75-ohm coaxial cable for
S/PDIF connections.
