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.
When to Use the Channel and Automix Equalizers
Apply Automix EQ to make system-wide changes, such as a treble boost to improve speech clarity. Use Channel EQ to make
adjustments to a specific channel. For example, to reduce unwanted noise picked up by only one channel.
Equalizer Applications
Conferencing room acoustics vary based on room size, shape, and construction materials. Use the guidelines in following ta­
ble.
EQ Application
Treble boost for improved speech intelligibility
HVAC noise reduction
Reduce flutter echoes and sibilance
Reduce hollow, resonant room sound
Suggested Settings
Add a high shelf filter to boost frequencies greater than 1
kHz by 3-6 dB
Add a low cut filter to attenuate frequencies below 200 Hz
Identify the specific frequency range that "excites" the room:
1. Set a narrow Q value.
2. Increase the gain to between +10 and +15 dB, and
then experiment with frequencies between 1 kHz and
6 kHz to pinpoint the range of flutter echoes or sibi­
lance.
3. Reduce the gain at the identified frequency (start be­
tween -3 and -6 dB) to minimize the unwanted room
sound.
Identify the specific frequency range that "excites" the room:
1. Set a narrow Q value.
2. Increase the gain to between +10 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 be­
tween -3 and -6 dB) to minimize the unwanted room
sound.
