Sennheiser MKH 20 Operation & User’s Manual

MKH 20 P 48 Microphones | RF Symmetrical Capsule Condenser Microphone 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’. 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 Recommended Accessories MZA 14 P 48 U battery power supply unit Cat.
