Measurement Microphone MM 220

Measurement Microphone MM 220

Description

The 1/2 ”measuring microphone MM 220 opens up the possibility of using high quality, pre-polarized measuring microphone capsule MK 250 on measuring systems with phantom power.

The electrical connection is made via a permanently connected, two-meter-long XLR cable.

We recommend the MH 64 microphone holder with a 1/2 ”clamp to hold the microphone. The use of the 1/2 ”measuring microphone capsule accessories such as windshield, nose cone, dry adapter etc. is possible without any problems.

The measurement microphone can be calibrated with the Pistonfon Type 5002 or with other suitable sound pressure calibrators.
