MKH 20 P 48
Microphones |
General Description
The omni-directional MKH 20 is usually used as a main microphone for
orchestras and solo instruments, and picks up the natural acoustics of
the room, though it does have a much wider range of applications as
omni-directional microphones do not suffer from 'proximity effect'.
Cable pictured is an accessory not supplied with the microphone
Features
Exceptionally flat frequency response, switchable for near and diffuse
field applications
High-frequency response can be accentuated by means of a pressure
build-up ring
Slightly increasing directivity at high frequencies to adjust tonal balance
Exceptionally low inherent self-noise
Transformerless and fully floating balanced output
Switchable pre-attenuation
Black, anodised light metal body
Delivery includes: 1 MKH 20, 1 MZS 40 shock mount,
1 MZW 41 windshield, 1 pressure build-up ring
