Bosch PRS-4OMI4 OMNEO Interface

Overview
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.

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
