I got similar problem with my UMIK-1 (700-2523). Its default gain is internally set to 12 dB. The Sens Factor of the cal. file is -6.499 dB. I checked UMIK-1 in REW against an SPL meter (TES 1350A Type 2), a mic calibrator (94 dB) and CLIO system included mic. The UMIK-1 SPL reading is offset (lower) for about 5 dB. ASIO4ALL was used. I changed the Sens Factor to -11.499 dB to get close enough reading. Is it just a typo or systematic error in production? Can I trust the response cal. data?
