Adjusting the bass filter (B) The 914 has been designed for an extended lowfrequency bass response. With certain live or close instrument miking applications, an over-emphasis of the low frequencies can occur. This can be compensated for by the 6 dB/octave roll-off filter. The cut-off filter reduces low-frequency wind noise by 18 dB/octave. Frequency response curves with different filters
