M2210 - Extended Performance
Measurement Microphone 

The plug-on measurement microphones M4260 or M2210 form together with the XL2 a comprehensive sound level meter and acoustic analyzer. The microphones are 48 VDC phantom powered and include the pre-amplifier and an electronic data sheet. The M4260 or M2210 combine a high dynamic range and wide frequency range with low noise.

• M4260 Measurement Microphone (class 2)
• M2210 - Extended Performance Measurement Microphone,
  (class 1 frequency response)

A remarkable advantage of the XL2 is the flexible user interface. The measurement screens may be personalized and only a limited subset of the comprehensive functionalities enabled for simplified operator interfaces. Advanced users may access all menus, settings and store their preferred measurement configurations. For basic users offers the XL2 Audio and Acoustic Analyzer fixed operator interfaces with specific pre-defined settings. The XL2 boots up with exactly the required measurement parameters according the pre-defined instrument configurations. This ensures accurate measurements achieved by advanced and basic users.
