Setting the Microphone

Content Id: 8204444200


Introduction

The camcorder features 4-channel linear PCM (LPCM) or 2-channel AAC audio recording and playback for MP4 clips, and 4-channel LPCM audio recording and playback for XF-AVC clips. The sampling frequency is 48 kHz.

You can record audio using the INPUT terminals* (commercially available microphones or analog line-in audio sources), the MIC terminal (commercially available microphones) or the built-in microphone.

The audio signal will be output along with the video signal from the SDI OUT terminal ( only) and HDMI OUT terminal. You can record this audio signal on an external recorder.

* Requires that the handle unit be correctly attached to the camcorder.

Selecting the Audio Format of MP4 Clips

When recording MP4 clips, you can set the audio format to AAC (2 channels, 16 bit) or LPCM (linear PCM, 4 channels, 16 bit). When the resolution is set to 1280x720, the audio format is set to AAC and cannot be changed.

1. Set the power switch to CAMERA.

2. Press the MENU button.

3. [ Recording Setup] -⋗ [ Audio Format].

4. Select the desired option.

5. Select [ ].

Caution

Select AAC format when versatility (the ability to play back on most devices) is more important. Select LPCM format when audio quality is the priority.

Audio Settings and Recorded Audio Channels

Which audio inputs are recorded to which audio channels is determined by a combination of menu settings, whether the handle unit is attached, and other audio-related controls on the camcorder. The following table gives an overview of the possible combinations.

Recording Audio from the INPUT Terminals to CH1/CH2

1. Set the corresponding AUDIO IN switch to INPUT 1 or INPUT 2.

2. To select the audio source, set the corresponding INPUT switch to MIC (microphone) or LINE (audio device).

Caution

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.

Recording the Same Audio Input to Two Channels

By default, when using the INPUT terminals, each audio input is recorded to a separate audio channel (INPUT 1 to CH1 and INPUT 2 to CH2). If necessary (for example, as an audio backup recording), you can record the audio input into the INPUT 1 terminal to both audio channels, CH1 and CH2. In that case, you can adjust the audio recording levels of each channel independently of each other.

1. Select [ Audio Setup] -⋗ [CH2 Input].

2. Select the desired option.

[ INPUT 2 ]: Records audio to each channel separately. Audio input into INPUT 1 is recorded to CH1, while audio input into INPUT 2 is recorded to CH2.
[ INPUT 1 ]: Audio input into INPUT 1 is recorded to both channels. Audio input into INPUT 2 will not be recorded.

3. Select [ ].

Selecting the Audio Input Recorded to CH3/CH4

When the audio format is LPCM (4-channel audio recording) and CH1/CH2 are set to the INPUT terminals, you can select the audio input that will be recorded to channels CH3/CH4.

1. Select [ Audio Setup] -⋗ [CH3/CH4 Input].

2. Select the desired option.

When [ Built-In Mic/MIC Terminal] is selected, the camcorder will record audio from the built-in microphone unless an external microphone is connected to the MIC terminal.

3. Select [ ].

Recording Audio from the Built-In Microphone or MIC Terminal to CH1/CH2

1. If the handle unit is connected to the camcorder, set the corresponding AUDIO IN switch to INT.MIC/MIC.

2. To use an external microphone, connect it to the MIC terminal.

Caution

You can supply power to an external microphone compatible with plug-in power.
The camcorder will record audio from the built-in microphone unless an external microphone is connected to the MIC terminal.

Adjusting the Audio Recording Level

You can adjust the audio recording level of the various audio channels using the audio controls on the handle unit or the audio screen in the FUNC menu. The audio screen shows an overview of the audio channels used and, for each audio channel: the audio input currently selected, whether the audio recording level is adjusted automatically or manually and the audio level indicator.

Automatic Audio Level Adjustment for CH1 or CH2

When the handle unit is attached to the camcorder, set the audio level switch of the desired channel to A (automatic) to let the camcorder automatically adjust that channel’s audio level. If the handle unit is not attached, adjust the audio levels using the FUNC menu.

Caution

Automatic Level Control (ALC): Linking or separating the audio adjustment of CH1/CH2 or CH3/CH4 (INPUT terminals / MIC terminal)

When the INPUT 1 and INPUT 2 switches are both set to the same type of audio source (line input or microphone), you can link the audio level adjustment for both inputs with the MENU -⋗ [ Audio Setup] -⋗ [INPUT 1/2 ALC Link] setting. When the [ Linked] option is selected, you can use CH1’s audio level switch and dial to adjust both CH1 and CH2, or select [CH3/4] in the FUNC menu's audio screen to adjust both CH3 and CH4.

Conversely, you can set MENU -⋗ [ Audio Setup] -⋗ [MIC ALC Link] to [ Separated] in order to separate the audio level adjustment for the L and R channels of an external microphone connected to the MIC terminal. This allows you to adjust each channel independently in the FUNC menu's audio screen.

Manual Audio Level Adjustment for CH1 or CH2

When the handle unit is attached to the camcorder, adjust the audio level using the controls on the handle unit. If the handle unit is not attached, adjust the audio levels using the FUNC menu.

1. Set the audio level switch of the desired channel to M (manual).

2. Turn the corresponding audio level dial.

Caution

For reference, 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 screen will go to the right of the –18 dB mark (one mark right of the –20 dB mark) only occasionally.

3. Close the protective cover to prevent the audio controls from being changed inadvertently.

Audio Level Adjustment Using the FUNC Menu

When the audio format is LPCM (4-channel audio recording), use the audio screen in the FUNC menu to adjust the audio recording levels for CH3 and CH4. If the handle unit is not attached to the camcorder, you must use the audio screen to adjust the audio recording levels for CH1 and CH2 as well.

1. Select -⋗ [ Audio ].

2. Select the channel or pair of channels to adjust.

3. Select [ Automatic] or [ Manual].

If you selected automatic adjustment, skip to step 5.
If you selected manual adjustment, continue the procedure to adjust the audio recording level.

4. Touch and hold [ ] or [ ] to adjust the recording level as necessary.

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.

5. Select [ ].

Caution

When the audio level meter reaches the red point (0 dB), the sound may be distorted.
If the audio level display is normal but the sound is distorted, activate the microphone's attenuator.
We recommend using headphones to check the sound level while adjusting the audio recording level or when the microphone attenuator is activated.

Caution

Audio peak limiter

If at least one of the channels is set to the INPUT terminals and manual audio level adjustment, you can activate the audio limiter to lessen audio distortions. When activated, the audio limiter will limit the amplitude of audio input signals when they start to distort. Use the MENU -⋗ [ Audio Setup ] -⋗ [INPUT 1/2 Limiter] setting.

Microphone Sensitivity (INPUT Terminals)

When one of the audio channels is set to the INPUT terminals and the corresponding INPUT1 or INPUT2 switch is set to MIC or MIC+48V, you can select the external microphone’s sensitivity.
