THE WM400D'S DIGITAL FEATURES
Channel Mode
The channel number of the WM400D will be
displayed in the 4 digit display, unless adjust-
ments are being made to other feature's prop-
erties. The channel number set should match
that of the WM60 or WM70 transmitter to al-
low the wireless system to work successfully.
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. 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 fidelity 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 flat.
Low Cut Filter
A low cut filter allows users to cut low frequen-
cy 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 filter's cut off frequency
is adjusted in Hz increments (0 Hz incre-
ments over kHz) between 0 Hz and 2 kHz.
The default setting is 20 Hz.
WM SERIES
High Cut Filter
The high cut filter 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 filter's cut off frequency is ad-
justed in Hz increments (0 Hz increments
over kHz) between 20 kHz and 60 Hz. The
default setting is 20 kHz.
TROUBLESHOOTING
No signal?
● Ensure both transmitter and receiver are
set to the same channel.
● Check the power lights on both receiver
and transmitter. If one of them is off, check
the device's power supply is connected
correctly.
● Make sure the "wireless" volume control on
the Performer speakers is turned up (WM-
SYS and WM-SYS2 only).
Weak signal?
● Try maintaining a better line-of-site connec-
tion between the transmitter and receiver.
● Change both transmitter and receiver to a
new frequency.
Poor quality signal?
● It is important to remember that no other
devices should be sending signals on the
same frequency channel that you are us-
ing.
● If another device is found on the same
frequency channel, find another suitable
channel.
