PRA-IM2A2 Audio interface module, 2x2
PRA-IM2A2 Audio interface module, 2x2
A 2x2 audio interface module for PRAESENSA, with supervised control I/O over redundant OMNEO.
Bridge the signals a PRAESENSA install actually has. This 2x2 interface module runs in analog mode — two balanced mic/line inputs with switchable phantom power and two balanced line outputs — or in digital mode, moving two virtual connections between Dante and OMNEO. Two supervised control inputs and two SPDT relay contacts tie in external switches and circuits. Dual Ethernet with RSTP and Power over Ethernet keeps it redundant and simple to cable. Certified to EN 54-16 and ISO 7240-16, it fits on a DIN rail.
Key features
Work either way
analog mic/line I/O or 2 virtual Dante-to-OMNEO connections.
Wire in the building
2 supervised control inputs and 2 SPDT relay contacts.
Stay redundant
dual Ethernet with RSTP, powered over one or both PoE ports.
Hold the signal clean
20 Hz to 20 kHz response, distortion under 0.01 percent.
Meets life-safety code
certified to EN 54-16 and ISO 7240-16 on a DIN-rail mount.
Watch the audio lines
optional pilot-tone supervision flags faults on line-level audio connections.
