Prodipe PROBL21

A capsule designed for the stage, signed "Lanen" in the Prodipe range

The BL21 Lanen Double Bass is part of a new range of instrument microphones intended for live sound capture of acoustic instruments. The central focus of the project is the capsule : Prodipe developed an electret capsule capable of handling very high levels to preserve the instrument's dynamics and timbre even in noisy environments. This approach, developed in collaboration with Ludovic Lanen and tested with instrumentalists, aims for reliable, consistent, and easy-to-use capture for demanding musicians.

Who is this double bass microphone for, and in what contexts should it be used?

This microphone is designed for double bass players seeking faithful sound reproduction on stage, during amplified rehearsals, or for live recordings where quick setup is as important as sound quality. It suits both intermediate musicians looking to step up their sound definition and professionals needing a robust and stable solution from one concert to the next.

Thanks to its unidirectional pattern and high sound level tolerance, it is particularly relevant in jazz, contemporary music, traditional music, and amplified orchestra contexts, where the double bass must remain clear in the mix without losing its acoustic character.

Sound Characteristics

The BL21 Lanen Double Bass relies on a very stable electret capsule : the frequency response (50 Hz to 20 kHz) maintains the low-end foundation while preserving air and attack for the definition of pizzicatos and bowing nuances. Its ability to handle up to 140 dB limits distortion on loud passages and helps maintain a clean sound even in close proximity.

The mounting plays a crucial role here: the flexible clamp strongly isolates unwanted vibrations, while the gooseneck allows fine placement at the heart of the instrument's projection. The result is a more consistent sound, less sensitive to handling noise, and better control over the balance between body, attack, and harmonics.

Recommended Compatible Accessories

For wireless configuration, this microphone is UHF compatible via the DSP - UHF Bodypack Instrument Prodipe (sold separately). Also plan for a 48 V phantom power supply available from a mixer, audio interface, or microphone preamp, necessary for operation via the XLR connector.
