Schoeps CUT 60 Miniature Low-Cut Filter 60 Hz, 24dB/Oct Schoeps

• recommended for use with the MK41 on a boom
• can be screwed between MK capsules and CMC amplifier
• very effective suppression of low-frequency wind noise and solid-borne noise
• extremely steep filter (24dB/oct.)
• The signal "speech" is not affected.

In particular, pressure-gradient transducers (directional microphones) produce very high infrasonic signal levels when exposed to wind or in elastic suspensions. These can saturate an input transformer or an amplifier stage even before the audible portion of the disturbance becomes noticeable.
To avoid this, a very sharp (24 dB/oct) infrasonic filter at 60 Hz is permanently engaged. It has no effect on speech.
