Approximately 500 msecs. after you changed a polar pattern, preattenuation, or bass cut
setting, your settings will be saved automatically. If you switch phantom power off and
back on later, these settings will be restored automatically.
Preattenuation Pad
Figure 2: Preattenuation Pad
Selector 2 on the microphone rear panel (refer to fig. 2) lets you increase the headroom
by 6 dB, 12 dB, or 18 dB for distortion‑free close‑in recording. The preattenuation pad
prevents the microphone's ouptut level, particularly at low frequencies, to overload the
mixer input.
To keep noise levels in the microphone input stage as low as possible, the entire trans‑
ducer section uses extremely high‑impedance circuitry. Therefore, the selected (changed)
polar pattern or preattenuation setting will take about 10 to 15 seconds to become fully
active.
Bass Cut Filter
Figure 3: Bass Cut Filter
Selector 3 on the microphone rear panel (refer to fig. 3) reduces low-end distortion cau‑
sed by footfall or wind noise, etc.
The filter takes effect under 160 Hz and filters 6 dB/octave. The bass cut also minimizes
the proximity effect that may arise in close‑miking applications (less than 6 inches
(15 cm)).
