If Channel Volume Is Too High
If a channel is not clipping but the channel slider level control must be set below the
−
20
dB position to achieve the proper volume level, the
Input
Gain
control setting is too high.
Set the channel slider control knob to the 0 dB position and adjust the
Input Gain
control
until the desired volume level is achieved. Reduce the
Input
Gain
by turning the knob
counterclockwise.
High/Low Pass
High-pass filters allow signals that are higher than the specified frequency and attenuate
signals that are lower. Low-pass filters allow signals that are lower than the specified fre
-
quency and attenuate signals that are higher. When combined, they are known as a
band-
pass filter
. Band-pass filters can be used to tailor the frequency response of a microphone
exclusively for vocals, which can be very useful in a noisy environment to filter out the
higher and lower frequencies that could mask the human vocal range during announce
-
ments.
You can specify the range of frequencies that will pass through the high-pass and low-
pass filters and select the type of filter that is used through the channel’s
High/Low Pass
drop-down menu option.
