A Key Component of the Série 21
Designed as the companion for the Série 21 instrument capsules, the BP21 replaces the phantom power from a console by providing a clean voltage without quality loss. It secures your recordings whenever the existing equipment does not offer 48 V.
Who Is It For and What Are Its Uses?
Ideal for mobile musicians, teachers, home studios, and live recording, the BP21 ensures reliable power for the GL21, SB21, BL21, CL21, VL21, PL21, DL21, and AL21, whether in rehearsal, on stage, or on location recording.
Features and Practical Benefits
Powered by a 9-volt battery, the compact metal box protects the signal and fits between the microphone and your interface via mini-XLR/XLR. The "Low-Frequency Roll-Off" selector helps reduce rumble and handling noise, while "Flat" preserves the microphone's natural response.

Customer reviews
What customers say
Summarized and selected by AI from recent customer reviews
Phantom power supply with practical clip-on design for instrument microphones. Customers praised its "excellent value" and ease of use, particularly for violin and cello amplification. However, some noted the 9V battery is outdated compared to competitors, and battery installation can be difficult. Works well but unnecessary if your amp has phantom power.

I bought this product for the microphone of the same brand and I think it is very good except to put the battery where I had trouble because I don't find it practical to slide the battery.
Otherwise it's also a shame to have only one microphone possible, I would have liked to have 2 microphones possible to connect.
Otherwise on the positive side, it works very well and so you plug the microphone directly into it before the console and it stays attached to the belt very easily.
So good product from Prodipe in my humble opinion but do it with 2 microphone connections and then it will be purely brilliant.Automatically translated
