The camcorder features two-channel linear PCM audio recording and playback with a sampling frequency of 48,000 kHz. You can record audio using the built-in microphone, optional external microphone (XLR terminal) or line input (XLR terminal). You can select the audio input independently for channel 1 and channel 2.
Using the Built-in Microphone
Set the <AUDIO IN> switch of the desired channel to <INT>.
- Configuring the Low-Cut Filter
Audio recording can be optimally configured to match the characteristics of the audio source.
1. Press the <MENU> button.
2. Open the [Int. Mic Low Cut] submenu.
Select [Audio Setup] -> [Audio Input] -> [Int. Mic Low Cut] in that order.
Push the <joystick> up/down or turn the <SELECT> dial to select the desired submenu, and then press <SET>.
3. Select the desired option and then press <SET>.
OFF: For recording audio under usual conditions.
LC1: For recording mainly peoples voices.
LC2: For reducing the background sound of wind when recording outdoors in windy surroundings (for example, on a beach or close to buildings). Note that when you use this setting some low-frequency sounds may be suppressed along with the sound of wind.
- Selecting the Built-in Microphones Sensitivity
Audio recording can be optimally configured to match the sensitivity of the audio source.
1. Press the <MENU> button.
2. Open the [Int. Mic Sensitivity] submenu.
Select [Audio Setup] -> [Audio Input] -> [Int. Mic Sensitivity] in that order.
3. Select the desired option and then press <SET>.
Normal: For recording audio under usual conditions.
High: For recording audio at a higher volume (+6 dB).
- Activating the Built-in Microphones Attenuator
If the audio level is too high and the sound sounds distorted, activate the microphone attenuator (12 dB).
1. Press the <MENU> button.
2. Open the [Int. Mic Att.] submenu.
Select [Audio Setup] -> [Audio Input] -> [Int. Mic Att.] in that order.
3. Select [On] and then press <SET>.
Using an External Microphone or Line Input
2. Set the <AUDIO IN> switch of the desired channel to <EXT>.
3. Set the XLR terminal switch of the desired channel to <LINE> or <MIC>.
- To supply a microphone with phantom power, set the switch to <MIC+48V> instead. Make sure to connect the microphone first, before turning the phantom power on. Keep the microphone connected when turning off the phantom power.
- When using the XLR terminal to record to only one channel, use the CH1 input terminal and set the XLR terminal switch for CH1 to <LINE>, <MIC> or <MIC+48V>.
- Selecting the Recording Channel
You can select to which channel the camcorder will record audio.
1. Press the <MENU> button.
2. Open the [XLR Rec Channel] submenu.
Select [Audio Setup] -> [Audio Input] -> [XLR Rec Channel] in that order.
3. Select the desired option and then press <SET>.
CH1: Records audio to each channel separately. Audio input into CH1 is recorded to channel 1, while audio input into CH2 is recorded to channel 2.
CH1/CH2: Audio input into CH1 is recorded to channels. Audio input into CH2 will not be recorded.
- Adjusting the External Microphones Sensitivity
You can adjust the external microphones sensitivity if the XLR terminal switch is set to <MIC> or <MIC+48V>.
1. Press the <MENU> button.
2. Open the desired XLR terminals sensitivity submenu.
Select [Audio Setup] -> [Audio Input] -> [XLR1 Mic Trimming] or [XLR2 Mic Trimming] in that order.
3. Select the desired level and then press <SET>.
[+12 dB], [+6 dB], [0 dB], [6 dB], [12 dB]
- Activating the External Microphones Attenuator
You can activate the external microphones attenuator (20 dB) if the XLR terminal switch is set to <MIC> or <MIC+48V>.
1. Press the <MENU> button.
2. Open the desired XLR terminals microphone attenuator submenu.
Select [Audio Setup] -> [Audio Input] -> [XLR1 Mic Att.] or [XLR2 Mic Att.] in that order.
3. Select [On] and then press <SET>.
CAUTION
- When connecting a microphone or device that does not support phantom power, make sure to set the XLR terminal switch to <MIC> or <LINE>, respectively. If you set the switch to MIC+48V, the microphone or device may be damaged.
- If [XLR Rec Channel] is set to [CH1/CH2], audio that is input to CH2 cannot be recorded.
Adjusting the Audio Level
You can set the audio level to auto or manual for each channel. When CH1 and CH2 are set to the built-in microphone, the settings for CH1 will automatically be applied to CH2.
- Automatic Audio Level Adjustment
Set the <AUDIO LEVEL> switch of the desired channel to < A > (automatic) to let the camcorder automatically adjust that channels audio level. If CH1 and CH2 are set to the built-in microphone and you set CH1 to automatic audio level adjustment, then the camcorder will also automatically adjust the audio level for CH2.
REFERENCE
When CH1 and CH2 are set to the same audio input (external microphone or external line input), if the audio level is set to automatic, you can use the [Audio Setup] -> [Audio Input] -> [XLR ALC Link] setting to link the audio level adjustment of channels.
- Manual Audio Level Adjustment
You can set the audio level for each channel manually from -  to 18 dB.
1. Set the <AUDIO LEVEL> switch of the desired channel to < M >.
2. Turn the corresponding <AUDIO LEVEL> dial to adjust the audio level.
- For reference, the 0 corresponds to - , 5 corresponds to 0 dB, and 10 corresponds to +18 dB. - As a guideline, adjust the audio recording level so that the audio level meter on the side panel will go to the right of the 18 dB mark only occasionally.
3. Setting the switch to <  > will keep the dial set at its current position and prevent it from being turned.
REFERENCE
You can activate the audio peak limiter to prevent audio distortions. When activated, the audio peak limiter will limit the amplitude of audio input signals when they exceed -4 dBFS. Use the [Audio Setup] -> [Audio Input] -> [Limiter] setting. The audio peak limiter can be activated if at least one of the channels is set to manual audio level adjustment.
NOTE
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.
