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
Custom Presets
Use presets to quickly save and recall settings. Up to 10 presets can be stored on each device to match various seating
arrangements. A preset saves all device settings except for the Device Name, IP Settings, and Passwords. Importing and ex-
porting presets into new installations saves time and improves workflow. When a preset is selected, the name displays above
the preset menu. If changes are made, an asterisk appears next to the name.
Note: Use the default settings preset to revert to the factory configuration (excludes Device Name, IP Settings, and Passwords).

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.
