Audio Level Adjustment for CH3, CH4 or CH3/CH4
1 Select > [
¡
Audio Setup] > [Audio Rec Level CH3], [Audio Rec Level CH4] or [Audio Rec Level
CH3/CH4] > [Automatic] or [Manual].
• If you selected [Automatic], the rest of the procedure is not necessary. If you selected [Manual], continue the
procedure to set the audio recording level.
2 Select > [
¡
Audio Setup] > [CH3 Level], [CH4 Level] or [CH3/CH4 Level] > Desired audio level.
• For reference, 0 corresponds to – , 50 corresponds to 0 dB, and 100 corresponds to +18 dB.
• As a guideline, adjust the audio recording level so that the audio level meter on the screen will go to the right
of the –18 dB mark (one mark right of the –20 dB mark) only occasionally.
NOTES NOTES
• We recommend using headphones when adjusting the audio level. If the input level is too high, audio may
become distorted even if the audio level indicator shows an appropriate level.
• If you set an assignable button to [Audio Level Indicator] (
A
123), you can press the button to turn the
onscreen audio level indicator on and off.
Advanced Audio Input Settings
In CAMERA mode, you can adjust various settings that affect the audio input depending on the terminal and
audio source used.
Microphone Sensitivity (INPUT Terminals)
You can select the external microphone’s sensitivity. The setting is applied when one of the audio channels in the
[
¡
Audio Setup] status screen is set to [INPUTx MIC] or [INPUTx MIC+48] (where “x” indicates the number of
the corresponding INPUT terminal (1 to 4)).
Select > [
¡
Audio Setup] > [INPUT 1 Mic Trimming] to [INPUT 4 Mic Trimming] > Desired
sensitivity level.
• You can select one of 5 sensitivity levels from –12 dB to +12 dB.
Automatic Level Control (ALC): Linking the audio level adjustment of CH1/CH2 or CH3/CH4
• When both CH1 and CH2, or CH3 and CH4, are set to the MIC terminal or INPUT terminals and to the
same type of analog audio source (external line input or external microphone), you can use the >
[
¡
Audio Setup] > [CH1/CH2 ALC Link] or [CH3/CH4 ALC Link] setting to link the audio level adjustment
of both channels.
• When CH1 and CH2 are linked, you can use the CH1 audio level switch and dial to affect both CH1 and
CH2. When CH3 and CH4 are linked, you can use the [Audio Rec Level CH3/CH4] and [CH3/CH4 Level]
settings to affect both CH3 and CH4.
Audio peak limiter
• If at least one of the channels is set to the INPUT terminals, an analog audio source and manual audio level
adjustment, you can activate the audio limiter to lessen audio distortions. When > [
¡
Audio Setup]
> [INPUT Limiter] is set to [On], the audio limiter will limit the amplitude of audio input signals when they start
to distort.
