The iSEMic CPX-1212
phantom powered measurement microphone provides a high quality, cost effective solution for precise acoustic measurements. The CPX-1212 microphone consists of the FP1212 class 1 mic capsule (as per IEC61094-4),
a CPX-12 body and comes with the calibration data for both, freefield and diffusefield, a holding clamp and the WS-12 windscreen included. The iSEMic preamp offers low noise and a wide dynamic range with
a max. 10Vrms (28Vpp) output (no clipping) while being powered from 48V of phantom power. The microphone is fully specified for 12, 24 and 48Volts of phantom power (IEC 12345) including P12L and P48H with
very low power requirements in combination with the high SPL handling capability. P48 powered it can handle 155dBspl and 142dBspl while being powered from 12V of Phantom Power (Ideal for wireless
measurement use). The nickel diaphragm capsule remains stable during temperature, humidity and atmospheric pressure changes unlike capsules based on Mylar/Polyester diaphragms. This yields in more accurate
test results.
It is a transformerless impedance balancing design with low impedance drive capability. The microphone unparalleled performance accepts load impedances of 6.8 kOhm (open circuit) down to 300 Ohm with extremely low voltage drop.
No matter what microphone preamplifier or computer interface you
use, the CPX-1212 can drive the input. Good to know when you have to change the measurement setup and equipment from venue to venue.
