Designed with a hypercardioid pickup pattern for isolation and feedback control, the D4 is equipped with a VLM diaphragm for natural, accurate sound reproduction. The D4 is lightweight, compact and easy to position. With a wide frequency response of 40 Hz - 18 kHz and the ability to handle SPLs in excess of 144 dB, the D4 is an excellent choice for miking instruments requiring precise low frequency reproduction such as large rack toms, floor toms, cajon, djembe, tympani, leslie bottom, bass flute, saxophone and baritone sax, trombone, acoustic bass, bass cabinets and small kick drums.
