The mic’s published frequency-response graph has changed since the mic’s introduction, although it is not known whether the change is due to component/design alterations or measurement processes. Please see the spec sheet under the specifications tab for more information about this product. Many sound engineers prefer the D4 for floor tom, Djembe, or any instrument with a similar voicing. The Audix D4 drum microphone offers both the frequency and sensitivity response useful for accurately recording drums and percussion instruments. The D4 is a hypercardioid dynamic instrument microphone, designed especially for low-frequency reproduction. Frequency Response 40Hz - 18kHz
The D4 is lightweight, compact and easy to position. - Live stage or recording - Large rack tom, floor tom, small kick drum- Cajon, djembe, tympani, leslie bottom- Bass flute, sax and baritone sax, trombone- Acoustic bass, bass cabs. Like all the D-series mics, the D4 uses Audix’ trademarked VLM Very Low Mass diaphragm, which is said to produce faster transient response and more natural sound. The D4 case is identical in size and shape to the D1, D2, and D3. Its compact design facilitates positioning around a drum kit, which is the D4’s primary application — kick drum and low toms. Impedance 280 ohms
The current chart shows a less pronounced boost, +6dB at 5kHz, with a secondary peak above 10kHz. While the D12 had a fatter and wider bottom, the D4 had a slightly deeper tone. This hypercardioid dynamic mic is perfect for instruments requiring additional bass response. Audix D4 With a wide frequency response of 40 Hz - 18 kHz and the ability to handle SPLs in excess of 144 dB, the D4 dynamic instrument microphone is an excellent choice for miking instruments requiring precise, low frequency reproduction such as large r The capsule mechanisms of the D1, D2, and D4 are virtually identical; the capsule diameter is just over 1'', and the inside diameter (approximate coil diameter) is about 22mm. The Audix D4 has a wide frequency response from 40 Hz in the low end to 18 kHz in the high end. (2.1 mV/Pa; 40 - 18,000 Hz). Like all dynamic mics, it handles high SPL without breaking up. The grille is made of “spring steel” mesh. Versus the RE20 the D4 had more punch, and again the top end was interestingly different. Polar Pattern Hypercardioid
Go way down low with the Audix D4! Interface: XLR, Microphone Technology: Small Element Dynamic And the high end on the D4 was much cleaner, minus that D12 midrange honk. The earlier chart (circa 2001) showed a rising high-frequency response, peaking at +9dB at 10kHz. The headgrille can be removed easily, exposing the dynamic capsule inside. Its hypercardioid pickup pattern reduces bleed from nearby sources. It has a transformerless, low-impedance, balanced output circuit. All are milled from a solid block of aluminum and finished in black. The D4 can be distinguished from the other models by the logo stamped on the mic, and by the color of the fine-mesh blast screen inside the black grille; on the D4, the inner screen is red, as pictured here. MIXI miked a single-headed kick with the D4 mounted on a 5-inch desk stand, and set up directly in front of the kick without a boom. Sensitivity 1.4 mV/Pa @1k. Hypercardioid Further, the current chart shows a low-frequency rolloff below 70Hz.
