Copy and Paste
Use to quickly apply the same PEQ setting across multiple channels.
1. Select the channel from the pull-down menu in the PEQ screen.
2. Select Copy
3. In the pull-down menu, select the channel to apply the PEQ setting and select Paste.
Import and Export
Use to save and load PEQ settings from a file on a computer. This is useful for creating a
library of reusable configuration files on computers used for system installation.
Export
Choose a channel to save the PEQ setting, and select Export to
file.
Import
Choose a channel to load the PEQ setting, and select Import from
file.
Equalizer Applications
Conferencing room acoustics vary based on room size, shape, and construction materials.
Use the guidelines in following table.
EQ Application
Suggested Settings
Treble boost for improved speech
intelligibility
Add a high shelf filter to boost frequencies
greater than 1 kHz by 3-6 dB
HVAC noise reduction
Add a low cut filter to attenuate frequencies
below 200 Hz
Reduce flutter echoes and sibilance
Identify the specific frequency range that
"excites" the room:
1. Set a narrow Q value
2. Increase the gain to b10 and
+15 dB, and then experiment with
frequencies between 1 kHz and 6 kHz
to pinpoint the range of flutter echoes
or sibilance
3. Reduce the gain at the identified
frequency (start between -3 and -6 dB)
to minimize the unwanted room sound
Reduce hollow, resonant room sound
Identify the specific frequency range that
"excites" the room:
1. Set a narrow Q value
2. Increase the gain to b10 and
+15 dB, and then experiment with
frequencies between 300 Hz and 900
Hz to pinpoint the resonant frequency
3. Reduce the gain at the identified
frequency (start between -3 and -6 dB)
to minimize the unwanted room sound
