OTR 1210

MADI Coax to MADI Fiber Transceiver

Datasheet Quickreference


The OTR 1210 is a MADI fiber transmitter and receiver combined in a single package. The module is designed to convert up to 64 audio channels bi-directionally (64 IN & 64 OUT) between MADI Optical and MADI Coaxial (electrical) formats. Conversion is real time [no latency] and does not degrade the signal quality. The OTR 1210 is compact and cost effective solution to extend the reach of MADI audio over long distances. When paired with another OTR 1210 at the receiving end (using two fiber links) you have a cost effective, zero latency MADI extender system for distances up to 10km.

Two versions are available. The singlmode fiber version will transport MADI over distances up to 10km, and the Multimode version up to 550m.

This yellobrik had a major hardware update. If your yellobrik has no usb port on it's length side please visit the yellobrik documents in our downloads section for the datasheet and quick reference.
