The AT4041SP studio pack offers two AT4041 studio condenser microphones. Engineered to meet the most critical acoustic requirements of professional recording, broadcast and live sound, the AT4041 features a smooth, extended frequency response with a slight rise in the high-frequency region and a transformerless output for very high SPL-handling capability. The element back plate holds a fixed charge and has been aged to provide energy stabilization. The surface of the back plate is precision milled to ensure maximum charge linearity, resulting in a reduction in both frequency response peaks and diaphragm break-up distortion.
