DPA 4055 baskagge mikrofon

DPA har konstruerat något så unikt som en baskagge mikrofon med linjär frekvenskurva.  Detta ger teknikern möjlighet att bli extra kreativ i placering av mikrofon, arbete med EQ mm.

DPA 4055 kan med fördel både placeras inne i och utanför baskaggen .
DPA lämpar sig väl både på turnén och i studion.
