Á High-pass filter
Cuts off unneeded low-band audio. The cutoff frequency is 80 Hz.
Á Echo canceller (p. 40)
Suppresses the voice echo that can occur when using a web
conferencing system that includes a speaker and mic.
Á Anti-feedback (p. 40)
Suppresses audio feedback.
Á Noise gate
Eliminates audio that is lower than the specified threshold level.
This is effective when the noise that you want to remove is separate
from the audio that you want to keep, and can be used to remove
hiss or other noise that is heard during periods of silence.
Á De-esser
Reduces sibilant noise (the sounds you hear when pronouncing “s”
words and other hissing sounds).
Á Compressor
Audio that exceeds the specified threshold level is compressed.
This reduces the difference between the maximum volume and
minimum volume, making the audio more comfortable for listening.
Á Equalizer
This is a three-band equalizer. It lets you adjust the volume by
boosting or cutting three frequency regions.
Á Voice changer (p. 41)
Transforms the pitch or character of the voice.
Á Delay (p. 41)
Outputs audio with a delay.
Á Reverb (p. 42)
Adds reverberation to the sound.
Using an Effect Preset
The V-160HD is equipped with effects that are adjusted for specific
environments. These are called “effect presets.”
The effect presets are created using a combination of three effects
(high-pass filter, compressor, equalizer).
Simply by selecting an effect preset, you can easily apply an effect
that’s appropriate for your situation.
MEMO
¹ If you want to make fine adjustments to a preset, use the
AUDIO INPUT menu to edit the high-pass filter, compressor,
and equalizer settings.
¹ You cannot overwrite the effect presets. Use the preset memories
to save the settings for presets you’ve edited (p. 48).
¹ When you load an effect preset, each preset setting is restored
to its default setting (factory defaults).
