4055 Kick Drum Microphone
Description
This 4055 Kick Drum Microphone has been optimized to pick up the true sound of the kick (bass) drum. This microphone delivers the renowned DPA sound, clarity and linear frequency response, both on axis and off axis. The low frequency response, dynamics and high-level capabilities of this mic are superb and result in a very tight, natural, well-defined sound. Full of highs and lows plus all the mids as well.
Features
-
Picks up the clear, true sound of the kick drum
-
Flat frequency response so you can shape the sound your way
-
Built tough to withstand rough use on the live stage
-
Asymmetric design for easy placement inside or outside the kick drum
Application Guide
Placement guide
The 4055 Kick Drum Microphone is easy to position both inside and outside the kick drum due to its asymmetrical design. This microphone is very flexible, allowing you to completely transform your sound design, just by moving the microphone or changing its angle.

Cleaning guide
Keep the microphone dry – away from water and cleaning fluids. Do not use sprays or fluids containing chemicals that could remove static electricity on or near the microphone. This could cause permanent damage.
Please note that the capsule is permanently fixed and can’t be changed.
The microphone grid is the only part that may be cleaned. To clean the grid properly, without risk of causing damage to the capsule, you have to unscrew it from the microphone body. Be aware that the mic capsule itself should not be cleaned in any way, as it will influence the performance.
The grid consists of two parts: the outer black metal mesh and an inner foam windscreen. Both parts may be cleaned separately.
All the parts should be assembled again in the opposite order. Be careful to align the foam windscreen in the outer black metal mesh. When remounting, take care to tighten the grid firmly.
