1 Description
To keep noise levels in the microphone input stage as low as pos- *) Note:
sible, the entire transducer section uses extremely high-imped-
ance circuitry. Therefore, the selected (changed) polar pattern or
preattenuation setting will take about 10 to 15 seconds to be-
come active.
3 Bass Cut Selector
Selector 3 on the microphone rear panel (refer to fig. 3) further re-
duces low-end distortion caused by footfall or wind noise, etc.
The filter slope is more than 12 dB/octave at the 40 Hz and 80 Hz
settings and 6 dB/octave at the 160 Hz setting. The
160 Hz setting minimizes the strong proximity effect that may
arise when close-in miking from less than 6 inches.

Overload Indication
The polar pattern indicator LEDs also provide an overload indi-
cation.
If the output level of the microphone equals or exceeds a value
of approximately 2 dB below the overload limit, the currently ac-
tive LED will change to red for about 0.3 seconds. If it does, we
recommend increasing the preattenuation by one or more
"notches" using Selector 2.
