Audio Operations
Applying Effects to Audio
You can apply effects and adjust the tone quality.
Applying Effects to Input Audio
This applies effects and adjusts the tone 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.
Menu item Explanation
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)
This compresses audio that exceeds a specified level.
Menu item Explanation
COMP This sets the compressor on or off.
COMP THLD
This sets the level used as the threshold at
which the compressor is applied. Compression is
applied to audio that exceeds the threshold.
COMP RATIO
This species the degree of compression applied
to the audio. The state in which no compression
is applied is defined as “1.”
COMP
ATTACK
This sets the time until compression starts when
audio exceeding the threshold is input.
COMP
RELEASE
This adjusts the length of time until compression
ends after audio falls below the threshold.
COMP AUTO
G
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 “COMP
THLD” and “COMP RATIO” settings.
The total of the “COMP MAKE UP G” setting value
described below and the value calculated by
auto makeup gain becomes the final output
volume level (up to +34 dB).
COMP MAKE
UP G
This adjusts the final output volume level after
applying the compressor.
Equalizer (EQ)
This adjusts the tone 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 tone 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 tone 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 tone quality in the low band.
