Audio Operations
Applying Effects to Audio
You can apply effects and adjust the sound quality.
Applying Effects to Input Audio
This applies effects and adjusts the sound quality for AUDIO IN, SDI IN, and HDMI IN audio.
1.
Select the [MENU] button 0 “AUDIO INPUT” 0 the input
audio.
2.
Select an effect menu item, then use the [VALUE] knob to
adjust it.
* For more information about effects, refer to the following
section.
3.
Press the [VALUE] knob to apply the setting.
4.
Press the [MENU] button to quit the menu.
High-pass filter (HPF 75Hz)
This cuts off unneeded low-band audio. The cutoff frequency is 75 Hz.
Menu item Explanation
HPF 75Hz This sets the high-pass filter on or off.
Delay (DELAY)
This outputs audio with a delay.
Delaying audio output lets you align the output timing of video
and audio.
Menu item Explanation
DELAY This adjusts the delay time for input audio.
Gate (GATE)
This mutes audio that is below a specified level.
Menu item Explanation
GATE This sets gate on or off.
THRESHOLD
This sets the level used as the threshold for removing
audio. Audio below the level set here is removed.
RELEASE
This adjusts the length of time until the audio is fully
attenuated after audio falls below the threshold.
Compressor (COMP/LMT)
This compresses audio that exceeds a specified level.
Menu item Explanation
COMP/LMT This sets the compressor on or off.
THRESHOLD
This sets the level used as the threshold at which the
compressor is applied. Compression is applied to
audio that exceeds the threshold.
RATIO
This species the degree of compression applied
to the audio. The state in which no compression is
applied is defined as “1.”
ATTACK
This sets the time until compression starts when
audio exceeding the threshold is input.
RELEASE
This adjusts the length of time until compression
ends after audio falls below the threshold.
AUTO GAIN
This switches the auto makeup gain feature on and off.
When this is set to “ON,” the final output volume
level after applying the compressor is automatically
adjusted according to the “THRESHOLD” and “RATIO”
settings.
The total of the “MAKEUP GAIN” setting value
described below and the value calculated by auto
makeup gain becomes the final output volume level
(up to +34 dB).
MAKEUP GAIN
This adjusts the final output volume level after
applying the compressor.
MEMO
When the compressor is turned on, the COMP/LMT indicator
lights up while compression is applied to the input audio.
Equalizer (EQ)
This adjusts the sound quality for each frequency band.
Menu item Explanation
EQ Hi This boosts or attenuates the high band.
EQ Hi FREQ
This adjusts the center frequency when changing the
sound quality in the high band.
EQ Mid This boosts or attenuates the middle band.
EQ Mid FREQ
This adjusts the center frequency when changing the
sound quality in the middle band.
EQ Mid Q
This adjusts the width of the frequency band when
boosting or attenuating the middle band.
EQ Lo This boosts or attenuates the low band.
EQ Lo FREQ
This adjusts the center frequency when changing
the sound quality in the low band.
Using an effect preset
The V-60HD provides seven types of effect presets that are
appropriate for specific environments. Simply by selecting
a preset you can easily apply the appropriate effect for your
purpose.
Each preset consists of a combination of three effects (high-pass
filter, compressor, equalizer).
