LOW-CUT FILTERS
Each channel of the MX410 features a switchable Low-Cut  lter set at 100Hz.
These Low-Cut  lters (sometimes called “High Pass”) cut frequencies below
100Hz signal and are e ective for reducing wind noise. For several audio appli-
cations engaging the Low-Cut  lter is bene cial, since little usable audio informa-
tion exists below 100 Hz. Especially for speech recording.
PHANTOM POWER
The MX410 can provide up to 10 mA of current to each input, su cient for the
most power-hungry condenser microphones. The MX410 Phantom Power utilizes
a  xed DC voltage which is resistively applied to pin-2 and pin-3 of an XLR input
connector relative to pin-1 (there is no voltage di erence between the signal on
pins 2 and 3; a dynamic microphone may or may not operate normally in the
presence of phantom power).
It is generally a good practice to turn o phantom powering when not using a
condenser microphone, as it can capacitively couple noise into the mic inputs
with poor mic cables. Also, be sure to turn o phantom powering when using rib-
bon microphones since an improperly wired cable can permanently damage the
microphone.
