Bosch PRS-4OMI4, OMNEO Interface

Bosch PRS-4OMI4, OMNEO Interface

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.

• Four OMNEO audio inputs and outputs
• Eight supervised control inputs and five control outputs
• Redundant Praesideo network connection
• Redundant OMNEO network connection
• Headphone connection and VU meter for audio monitoring

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 then 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.

Functions

The Praesideo OMNEO Interface can simultaneously interface up to four digital audio channels from OMNEO into an audio system and up to four audio channels from an audio system into an OMNEO network. This includes converting between the 44.1kHz sample rate used by Praesideo and the 48kHz 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 through their Open interfaces for control purposes.

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. The 2x 16 character displays and the rotary control enable local status inquiries. The display shows the VU meter reading when the audio monitoring mode is active. Audio can be monitored by headphones. The interface supports redundant network cabling of both an audio system and OMNEO networks. It gets its power from the network controller via the network cable. The unit is self-monitoring and continually reports its status to the network controller.
