Hilbe BOHO Active Ribbon Recording Microphone

The Hilbe BOHO is an active ribbon recording microphone that delivers vivid, natural sound with a wide low-frequency range and fast transient response. Its double-sided 0.02 mm pure aluminum foil ribbon and the Hilbe series MELCOR B-400-01 transformer give it the classic ribbon character in a versatile package. The figure-8 pattern and 130 dB maximum input SPL make it well suited to acoustic instruments, including strings, brass, pianos, drums, and percussion. Onboard high-pass filter and attenuation switches add control at the source, and the active design runs from 48V phantom power.
