Removing Noise from the Audio (Adaptive Noise Reduction / Low Frequency Cut )
You can remove noise from the input audio. Two effects are provided: "adaptive noise reduction" and "low frequency cut".
ÁAdaptive Noise Reduction
By continuously monitoring the input audio to detect noise during periods of silence, this removes only the noise component. Unlike conventional
noise reduction that removes sound of a specified frequency, this analyzes the frequency of the noise and removes it as appropriate for the
environment, resulting in a more natural sound.
* The presence or absence of voice in the input signal is determined according to the "talking detector" settings.
ÁLow Frequency Cut
This divides the region below 200 Hz into four bands, and cuts unneeded low-frequency regions while continuously analyzing each band. Unlike
conventional low cut, this does not weaken the sound of the low-frequency region.

Adaptive Noise Reduction

1 .
Press the MAIN [SETUP] button.
The AUDIO OUTPUT screen appears.
2 .
Touch <MAIN BUS>.
The MAIN bus setup screen appears.
3 .
Touch <ADAPTIVE NOISE REDUCTION>.
The adaptive noise reduction setup screen appears.
4 .
Touch <ON/OFF> to turn this "ON".
Adaptive noise reduction function turns on.
5 .
Touch <AUTO LEARN> to set it to "ENABLE".
The noise is automatically detected, and the noise is reduced.
* If you want to detect noise manually, touch <MANUAL MEASURE>.
When you touch <MANUAL MEASURE>, measurement occurs
automatically. When measurement finishes, the message
"COMPLETED" appears.
6 .
Touch <DEPTH> to set the depth (how aggressive the noise
reduction is).
7 .
If the ambient noise level is high, touch <TALKING
DETECTOR> to adjust the sensitivity.
* Increasing the value raises the sensitivity of the talking detector,
making detection easier even in noisy environments.
8 .
If you want to reset the noise-reduced result to its original
state, touch <FORGET LEARNING>.
* For details on the menu items, refer to "2: AUDIO" (p. 99).
9 .
Press the lit [SETUP] button to close the setup screen.

Low Frequency Cut

You can set low frequency cut as well from the MAIN bus setup screen.
1 .
Touch <LO FREQUENCY CUT> to turn it "ON".
Low frequency cut turns on.
