ULTIMATE MEASUREMENT MICROPHONE
The CM-145 is a very low noise, flat frequency response, omni-directional microphone built to IEC651 Type 1 standards and comparable to the B & K 4006. This is an electret condenser microphone with a 1/2″ diaphram of nickel-copper alloy. Included with the microphone is a shock mount, foam lined wood storage box and individual calibration chart.
This microphone is a great match to the high precision capabilities of Studio Six Digital AudioTools.
IEC651 Type 1 refers to a system of the sound level meter as in AudioTools combined with the microphone. For a discussion of Type 1, see this link towards the bottom.
