Antenna Diversity
A unique feature, not available anywhere else.


Antenna diversity permits the msi 189 to rapidly and automatically chose between two antennas, always selecting the one with the best signal.


For reception in a car, boat, helicopter or fixed wing aircraft, diversity delivers.


The msi 189 represents a complete systems approach to professional Multi Channel Television Sound reception. It provides the four key signals - mono, stereo, and SAP -- simultaneously, and offers total flexibility in monitoring. A convenient 75ohm high quality video output is also available as well as a wideband aural output.


All audio signals are transformer balanced, line level, presented on standard XLR connectors so no external boxes are required.


True non-intercarrier aural detection means complete immunity to the effects of ICPM, as well as reliable reception well beyond the limits of visual coverage.
