[Motorola] Pin-Out & Specs for HMN9083D Motorola mic?

Sat, 16 Feb 2002 09:00:46 -0500

So you just eliminated the PCB compression circuit and wired the
raw mic and speaker.  No compensating cap as is common?

Was the element an electret that require some power or some
other type?

My preference is to try and preserve the internal circuitry, if
possible, and handle the rewiring in the adapter -- not sure if
that is practical, and without specs all-but-impossible.

Thanks! doc
