Audio Operations
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 <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.
