Interact with this product in a Layout Tool:

The EMR Analogue Audio modules are key part of the EMR-audio router family, providing line level analogue audio connection options and expandability in blocks of 48. EMR offers expansion beyond the constrains of a single frame with TDM coax connection to the ADMX audio TDM crosspoint packet routing core.

ADMX cores can be paired up to provide a dual hot redundancy setup for ultimate audio crosspoint redundancy. The analogue audio input module provides dual redundant outputs and the output module provides failover on link and packet basis.

The EMR analogue modules can be combined with ADMX and other EMR audio modules for the ability to route audio universally across various formats: AES, analogue, MADI, Studer A-Link, Calrec Hydra2, SMPTE ST 2110-30, ST 302M, Dante® and embedded audio. This unique audio routing solution provides an extremely robust and flexible any-audio-type to any-audio-type in an unblocking manner down to the mono audio channel level.
