double-sided adhesive for positive mounting of the
microphone to a table or other flat architectural detail.
The microphone has a sensitivity of 23 mV/Pa and can
directly drive many microphone input stages with limited gain
reserve. The microphone is phantom powered over the range
from 9 to 52 volts dc.
