PRAESENSA audio connectivity expanded with new audio interface module
New PRAESENSA 2.20 software release support the new PRA-IM2A2 audio interface module
The PRA-IM2A2 Audio interface module adds two balanced analog audio inputs and outputs to the PRAESENSA system, combined with two configurable and supervised control inputs and voltage free control outputs. The audio inputs can connect to external microphones for calls, to music sources and to third party audio systems. The connection of the audio inputs can be supervised and be activated through one of the control inputs. The audio outputs can connect to external amplifiers or other audio devices, for example audio recorders. Alternatively the analog audio inputs/outputs can be replaced by either two Dante inputs or two Dante outputs, or one input and one output.
Easy integration
The PRA-IM2A2 enclosure allows for DIN rail installation near to the auxiliary equipment for short interconnections. The module only requires a connection to an OMNEO IP network with Power over Ethernet (PoE) for communication and for power supply combined.
Inputs and outputs
The audio interface module supports an analog mode and a digital mode, configurable in the software. The audio inputs and outputs depend on the mode.
In analog mode:
- Two audio inputs, electronically balanced, can be set as either line or microphone inputs with optional 48 V phantom power. Each input accommodates various signal sources, including single-ended ones.
- Two electronically balanced line-level audio outputs can function as zone outputs for amplifiers with analog inputs or interface with other systems. These outputs are also compatible with single ended connections.
In digital mode:
- Two virtual audio channels support the configuration to convert one Dante input stream into an encrypted OMNEO channel and conversely.
