High Cut Filter
The high cut lter allows users to remove
unwanted high-frequency sounds, which can
help to remove high frequency hiss and feed-
back, as well as make the audio signal more
suitable for use with subwoofer speakers.
The high cut lter’s cut off frequency is ad-
justed in 1 Hz increments (10 Hz increments
over 1kHz) between 20 kHz and 60 Hz. The
default setting is 20 kHz.
Channel Mode
The channel number of the WM400D will be
displayed in the 4 digit display, unless ad-
justments are being made to other feature’s
properties. The channel number set should
match that of the WM60 or WM70 transmit-
ter to allow the wireless system to work suc-
cessfully.
Delay Mode
Changing the delay allows audio engineers to
compensate for the distance between speak-
ers on stage and audience members at the
rear of the venue. Using the delay effect on a
speaker at the rear will ensure the audio from
the stage reaches audience members at the
rear at approximately the same time as the
audio from the rear-speaker. The delay time
is adjusted in 0.1 millisecond increments, be-
tween 0 and 300 milliseconds (holding the up
or down button down speeds up the adjust-
ment time)
EQ Mode
The different EQ modes allow users to adjust
various frequencies of audio to enhance cer-
tain instruments, remove sibilance, feedback
and other undesirable noises, and improve
the overall delity of sounds. There are 30
presets to choose from (check EQ Preset
page for more information), the titles of which
describe what the effect does to your audio.
The default setting, P0, is completely at.
Low Cut Filter
A low cut lter allows users to cut low fre-
quency sounds, ensuring stage rumble and
other unwanted low-frequency sounds are
removed from your audio. This can also help
adjust the frequency to be more suitable for
use with tweeters. The low cut lter’s cut off
frequency is adjusted in 1 Hz increments (10
Hz increments over 1kHz) between 10 Hz
and 12 kHz. The default setting is 40 Hz.
