CE marking compliance ensures strong resistance to electromagnetic noise and stable measurement.
By adopting the CCLD method, it can be connected to a large number of analyzers and amplifiers that also use this method.
Cables can be extended up to 100m (using recommended cables and CCLD current value of 2mA or higher).
Maintains compatibility with previous models and can be replaced.
The MI-3111 is a preamplifier for 1/2-inch back-electret condenser microphones. Its CCLD (constant current drive) system and BNC connector allow for direct connection to numerous CCLD-compatible amplifiers, analysis equipment, and data recorders. Furthermore, it conforms to the European safety standard CE marking and incorporates EMC (Electromagnetic Computing) measures, making it highly resistant to electromagnetic noise and minimizing interference. It is ideal for measuring and analyzing ambient noise and architectural acoustics, as well as for measuring and analyzing radiated sound pressure from electronic and mechanical equipment.
