CMA-9 Condenser Microphone

The CMA‐9 is a professional condenser microphone used for stage, studio and broadcast

applications. The CMA‐9 guarantees a clear, accurate response and flexibility to handle close

or distance miking for a wide variety of acoustic instruments. With a frequency response

from 25Hz to 20kHz the DMA‐9 condenser mic is an excellent choice for cymbals, hi‐hat,

drum overhead and ambient room miking.

The microphone adopts a 25mm pure gold large diaphragm capsule,

which has a cardioid polar pattern. The CMA‐9 comes with a strong

shock mount system (SHM1) that minimizes transmission of mechanical

noise and vibration

For higher sound pressure levels the pre‐attenuation of ‐10dB can be

applied. With the build in Low‐cut filter (bass roll‐off filter) you can

reduce picking up frequencies from 150Hz.

The durable roadworthy construction of the CMA‐9 includes the brass

housing, nickel plated surface and metal mesh grill.

Characteristics:

Adopting low noise, transformer free

Cardioid polar pattern, high sensitivity, low noise and wide dynamic

range
