APOWER LED: This blue LED is lit to indicate that power to the Remote Control Unit is ON. B Polar pattern selector: This rotary switch lets you select the microphone’s polar pat- tern from omnidirectional (fully CCW) to cardioid (center) to figure eight (fully CW). Be- tween these settings, there are six intermediate patterns. All switch positions are

detented, so all settings are easily and unambiguously reproducible.

C Preattenuation switch: This toggle switch lets you increase the microphone’s headroom by 20 dB for close-in recording with extremely low distortion. The preattenuation pad pre- vents the microphone's output level, particularly at low frequencies, from overloading the miniature transformers used in many mixer input stages, etc.

D Bass cut switch: This toggle switch lets you reduce low-end distortion caused by foot- fall or wind noise, etc. The bass cut filter also minimizes the proximity effect that close- in miking from less than 4 inches causes in any unidirectional microphone. The filter rolls off at 12 dB/octave from 80 Hz downward.
