Audio Operations
Applying Effects to Audio
You can apply effects to audio that is input and output to adjust its sound quality.
Applying Effects to Input Audio
This applies effects and adjusts sound quality for
audio input via AUDIO IN, MIC, SDI IN, and HDMI IN.
The following table shows the effects you can use
with the different input audio streams.

1.
Display the AUDIO menu (p. 12), then select the
effect menu item you want to use.
* For more information about effects, refer to the following
section.
2.
Use the A/B fader to adjust the setting value.
3.
Quit the menu (p. 12).
Equalizer (EQ)
This adjusts the sound quality for each frequency band.
SDI 1 (page 4/15) – MIC IN (page 10/15)
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.
Delay (DELAY)
This outputs audio with a delay.
Delaying audio output lets you align the output
timing of video and audio.
AUDIO DELAY (page 3/15)
This adjusts the delay time for audio inputs.
High-pass Filter (HPF)
This cuts off unneeded low-band audio. The cutoff
frequency is 75 Hz.
MIC IN (page 10/15)
Menu item Explanation
HPF This sets the high-pass filter on or off.
Compressor (COMP)
This compresses audio that exceeds a specified level.
MIC IN (page 11/15)
Menu item Explanation
COMP This sets the compressor on or off.
THRESHOLD
This sets the level used as the threshold when
compressing audio. Compression is applied to
audio that exceeds the level set here.
RATIO
This specifies 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.
Gate (GATE)
This mutes audio that is below a specified level.
MIC IN (page 11/15)
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.
