iSEMcon offers a variety of new acoustic
measurement microphones and associated
products on a budget. The newly developed
constant current powered microphones (CCP)
are well known in the market and compatible
with equipment from other manufacturers.
Other proprietary names*1 for the same
interface are ICP®, IEPE®, Deltatron®,
AcoTron®, Isotron®, Piezotron® and more.
See product overview for reference.
CCP powered microphones transform the high
impedance microphone output into a low
impedance voltage signal (less than 10 Ohms)
and are capable to drive long cables.
A big plus under todays EMI (Electromagnetic
Interference) requirements. All our microphones
are fully ESD protected. The EMM-07/13D080-CCP
also available with Phantom power option
(EMM-07/13D080-P48) has High Energy Surge
protection built-in.

IEC61672 class 1 frequency response
Our microphones are known to have an IEC61672 class
1 frequency response or being close to the class 1 limits.
This should not be misunderstood. The entire

Summarized: IEC 61672 class 1 addresses also the
temperature and pressure behavior and is not only limited
to “domestic” conditions and frequency response
linearity.
