Hire company Yorkshire Audio recently evaluated Audio-Technica's AT4054 vocal condenser microphones during the UK leg of the James Brown international tour. Keith Birtwhistle, front of House engineer for the show, carried out the trial employing the mics on keyboard and main vocal positions and was very impressed with the results. "We are always on the look out for new products which improve sound quality and add to the artists’ performance, and I would certainly put the AT4054s into that category. They provide a powerful, clear sound and are a dream to mix."
