AGC Mode
For setting whether to link the limiter operation of [CH1] and [CH2].
Select “Link” to link or “Separate” to separate.
[Setting Values: Link, Separate]
Enabled only when both the [AUX] input terminal and [INPUT1/INPUT2] input terminal are set to “LINE” or “MIC”, and CH1/CH2 of the [CH1/CH2 AUTO/MANUAL] switch is set to “AUTO”.
XLR Manual Level
For setting whether to link manual audio adjustment operation between [INPUT1] and [INPUT2] terminals.
Select “Link” to link or “Separate” to separate.
When this item is set to “Link”, adjust the recording level using the [CH1] recording level adjustment knob.
[Setting Values: Link, Separate]
Enabled only when both the [INPUT1/INPUT2] input terminals are set to “LINE” or “MIC”, and both [CH1]/[CH2] of the [CH1/CH2 AUTO/MANUAL] selection switches are set to “MANUAL”.
When this item is set to “Link”, [CH2] recording level adjustment knob is disabled.
Int. Mic Separation
For setting the enhancement level of the stereo effect of the built-in microphone.
On:
Enhances the stereo effect.
Off:
Does not enhance the stereo effect.
[Setting Values: On, Off]
Both [CH1] and [CH2] selection switches are set to “INT”.
When [Int. Mic Separation] is set to “On”, a 
icon is displayed on the status screen (audio input) while the function is operating.
Test Tone
For specifying whether to output the audio test signals (1 kHz) during color bar output.
[Setting Values: On, Off]
INPUT1/2 Wind Cut
For selecting whether to cut the low frequencies of the audio input signals (low-cut) when the [INPUT1/INPUT2] switch is set to “MIC” or “MIC+48V”.
Set this item to reduce wind noise from the microphone.
Both:
Enables low-cut on both the [INPUT1] and [INPUT2] terminals.
INPUT2:
Enables low-cut on the audio of the [INPUT2] terminal only.
INPUT1:
Enables low-cut on the audio of the [INPUT1] terminal only.
Off:
Disables low-cut.
[Setting Values: Both, INPUT2, INPUT1, Off]
Int. Mic Wind Cut
For selecting whether to cut the low frequencies of the audio input signals (low-cut) from the built-in microphone. Set this item to “On” to reduce wind noise from the microphone.
[Setting Values: On, Off]
Equalizer
You can correct the characteristic and enhance the sound of the connected microphone using this equalizer setting.
For setting the audio frequency from a 5-band equalizer.
Frequency:
100Hz, 330Hz, 1kHz, 3.3kHz, 10kHz
Variable level:
± 6dB (1dB step)
Audio will be recorded in the characteristic set in the equalizer.
Set all bands to “0 dB” to bypass the equalizer.
When the equalizer level is set to the + side, the audio may be distorted. In this case, reduce the recording level in Manual mode.
If the values of multiple frequencies are changed, the specified levels and the actual levels may be different due to interference between the frequency bands.
This function is enabled only when both [INPUT1/2 Wind Cut] and [Int. Mic Wind Cut] are set to “Off”.
Monitor
For setting the audio sound of the [ 
] terminal to stereo or mixed sound when the [MONITOR] selection switch on the LCD monitor is set to “BOTH”.
Mix:
Outputs mixed sound (mixed sound of CH1 and CH2) to both L and R.
Stereo:
Outputs stereo sound (outputs audio sound of CH1 to L, and CH2 to R).
[Setting Values: Mix, Stereo]
If both CH1 and CH2 are built-in microphones, stereo sound is output from the [ ] terminal regardless of the [Monitor] setting.
IFB/RET Monitor...
CH1(/2)
For configuring the output from the [ ] terminal during IFB Return over IP of each channel.
Auto:
Outputs upon mixing the IFB/Return over IP audio with the microphone audio when IFB/Return over IP audio input is detected. Outputs only the microphone audio when IFB/Return over IP audio input is not detected.
