Adjusting EQ
Select and adjust frequency, gain, and bandwidth in the equalizer.
Equalization Explained
The 4-band parametric equalizer is used to adjust the volume of independent, adjustable frequency ranges, to precisely shape
the frequency response. The equalizer can be bypassed for a flat frequency response.

Commonly used EQ Adjustments
Treble boost for improved speech intelligibility: Add a high shelf filter to boost frequencies greater than 1 kHz by 3-6 dB
Ambient 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 sound:
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 pin-
point 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 sound
Reduce hollow, resonant sound: Identify the specific frequency range that "excites" the sound and lower it:
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 between -3 and -6 dB) to minimize the unwanted sound
Select the center frequency of the filter to cut/boost.
Adjusts the level for a specific filter.
Adjusts the range of frequencies affected by the filter. The value is represented in octaves.
