Microtech Gefell KEM 970
The high degree of directional selectivity of the microphone requires the knowledge of the directions of incidence of useful sound as well as of disturbant sound. The more carefully the KEM 970 is adjusted in this relation, the better are the results which are gained.
The optimum adjustment can be reached by means of the position control indication on the front side of the microphone. The mean gain of about 5 dB of the useful signal level can otherwise be reached by room-acoustical means only by very high efforts and costs or not at all.
Another benefit of the KEM 970 is its capability of reducing the sensitivity when the distance to the sound source is diminished and the arrangement will follow the proposal in Fig.3.
Recommended applications of the KEM 970:
- at the stage edges or stage corners
- at the speaker’s stand (desk)
- the use for a table microphone
- in Radio and TV productions
- in Video conferences
- for the detecting of local disturbant sound sources
First experiences made with practical applications in TV productions, stage sound reinforcement systems and with the support of speech at the speaker’s stand have confirmed the decisive benefits of the Cardioid Plane Microphone in a lot of situations.
