Filters

DPA 401 7 features two switching filters which are controlled at the switching ring,

and a permanent third order high pass filter at 50 Hz (See fig. 3).

Switching filters

High boost: When the switching ring is turned on, the filter is on, giving +4 dB

at 8 kHz (shelving). It is recommended for any high frequency loss caused by use

of third party manufacturer's windshield. Use DPA WINDPAC® to avoid any high

frequency attenuation.

Bass roll-off: By turning the switching ring on, the filter is on, giving a first order

(6 dB/oct) bass roll off below 300 Hz. This decreases unwanted low frequency

disturbance from handling and wind noise. Furthermore, it can be used to tune

the desired amount of bass in a voice, as the bass response of the microphone

is influenced by the proximity effect. Short distances to a performer will usually

require the bass roll-off filter to be switched on to compensate for the low fre-

quency rise.
