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”.

Á

Adaptive 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.

Á

Low 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

.

The MAIN bus setup screen appears.

3 .

Touch .

The adaptive noise reduction setup screen appears.

4 .

Touch to turn this “ON”.

Adaptive noise reduction function turns on.

5 .

Touch to set it to “ENABLE”.

The noise is automatically detected, and the noise is reduced.

* If you want to detect noise manually, touch .

When you touch , measurement occurs

automatically. When measurement finishes, the message

“COMPLETED” appears.

6 .

Touch to set the depth (how aggressive the noise

reduction is).

7 .

If the ambient noise level is high, touch

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 .

* 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 to turn it “ON”.

Low frequency cut turns on.
