u Four OMNEO or Dante™ audio inputs and outputs

u Eight supervised control inputs and five control

outputs

u Redundant optical network connection

OMNEO, developed by Bosch, is a network protocol
for real-time uncompressed digital audio distribution
and control over industry standard IP networks.

• OMNEO’s media transport technology is Audinate’s
Dante™, a high-performance, standards‑based,
routable IP media transport system.

• OMNEO’s system control technology is Open Control
Architecture, or OCA. OCA is an open public standard
for the control and monitoring of professional media
networks.

• Both OMNEO’s media transport and system control
can run in encrypted mode for secure applications.

Praesideo

OMNEO or Dante™ audio channels can be configured
as inputs to a Praesideo system, where they can be
routed permanently or conditionally to any of the
zones or audio outputs. The routing conditions are
configured using the configuration software. Calls and
background music (BGM) sources can be routed to
OMNEO or Dante™ channels. Digital audio data is
directly converted between an audio system and
OMNEO, with no other audio processing than sample
rate conversion. Control inputs and outputs are
provided for external interfacing. The equipment can
be used free-standing (tabletop) or in a 19” rack.

DCN Next Generation

OMNEO or Dante™ audio channels can be configured
as inputs and outputs to a DCN Next Generation
system (DCN NG), where they can be used for
interpretation purposes. The control inputs and
outputs are used to enable and disable the audio
inputs and outputs and report channel status.
In combination with DICENTIS Conference System it
can be used to receive the floor audio from DICENTIS
Conference System and supplying the interpretations
from DCN NG to the DICENTIS Conference System.

Functions

The OMNEO Interface can simultaneously interface up
to four digital audio channels from an
OMNEO / Dante™ system into a Praesideo / DCN NG
system and up to four audio channels from a
Praesideo / DCN NG system into an OMNEO / Dante™
system. This includes converting between the 44.1 kHz
sample rate used by Praesideo / DCN NG, and the

48 kHz sample rate that OMNEO uses, as well as
conserving volume levels. It can also route audio
channels between itself and other OMNEO Interfaces,
in the same or in other audio system networks, or to
third party Dante™ units. Only audio channels are
routed via the interface, not control data. This means
that if units are used to link multiple systems, a PC
master must always access the Praesideo network
controllers / DCN NG CCUs through their Open
interfaces / APIs for control purposes.

Praesideo

The eight control inputs are freely programmable for
system actions, and priorities can be assigned to these
inputs. Five control outputs are freely programmable
for faults and call‑related actions. Control inputs can
also be programmed for momentary or toggle
operation using the configuration software. Each
control input has the ability to monitor the attached
line for open and short‑circuits.

DCN Next Generation

The eight control inputs are used to enable or disable
the 4 inputs and outputs. The first four control outputs
are used to indicate the engaged state of the channel
assigned to the output. The fifth output indicates the
status of the optical network.

Controls and indicators

• 2 x 16 character LCD status display shows the VU
meter reading when the audio monitoring mode is
active. Audio can be monitored by headphone.

• Rotary/push control for menu control and headphone
volume.

Interconnections

The interface supports redundant network cabling of
both an audio system and OMNEO networks. It gets its
power from the Praesideo network controller /
DCN NG CCU via the network cable. The unit is
self‑monitoring and continually reports its status to
the network controller / CCU.

• Two optical network connections

• Two RJ45 Ethernet connectors for OMNEO

• Eight control inputs to enable audio inputs and audio
outputs

• Five control outputs to indicate channel engaged
state

• One headphone output 3.5 mm (0.14 in) stereo
