Code article : BDM301, BDM304, BDM308, BDM316, BDM332

The BDM3xx range of Analogue microphones were superseded in 2008 by the BDM4xx range of Serial Data microphones.

We can confirm that BDM3xx Microphones will be made obsolete in October 2019 and this is a “Last Time Buy” notification that these products will not be available for purchase after this date.


Suggested alternative
The BDM4xx range of Microphones can be used with a BDM400IF interface module to enable backwards compatibility for the majority of existing installations.

Warranty & support information 
We will continue to service and support BDM3xx Microphones products during the remaining warranty period and for the lifetime of the system, subject to component obsolescence.
