Cost effective measurement microphone suited for acoustical measurements including loudspeaker design, sound system setup and room acoustics. The CF-1 does not require 48 volts phantom power. You can connect it to microphone inputs that provide a DC power of 5-9 volts. We can offer the microphone with its own calibration chart providing its sensitivity and the frequency response curve. You can use this calibration file with audio measurement software like ARTA or Hobbybox.
