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.

Select the [MENU] button

“AUDIO INPUT”

the input audio.

Select an effect menu item, then use the [VALUE]

knob to adjust it.

* For more information about effects, refer to the following

section.

Press the [VALUE] knob to apply the setting.

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

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.
