JVC GY-HM600/620 Camera

Recording Audio

The JVC GY-HM600/620 uses a built-in

(Internal) microphone and two XLR (3-pin)

cable inputs for microphones such as

stick (hand-held) or wireless. 

The Internal microphone is used to

record NAT audio (natural or ambient

sound). This microphone records stereo

(2-channel) audio, which is great for

NAT audio, but bad for recording

interviews. Often, the voice ends up

competing with the NAT sounds,

especially if the ambient noise is

overwhelming. Also, voices tend to

sound distant when the person is a

distance away. When shooting

interviews, it's much better to use the

stick microphone or wireless.

Using Stick Microphones or Wireless

These accessory microphones can be connected to either the Input 1 or the Input 2 XLR terminals. The stick and the wireless microphones are ideally suited to record voices during interviews. For the clearest, sharpest reproduction of voices, it’s important to always consider first using the stick or wireless… and only use the built-in camera microphone as a last resort. Never start with the last resort first because audio quality is as important as video quality.

Using the Wireless Microphone

Connect the wireless receiver to INPUT 1 or 2 and attach it to the camera’s shoe (top track on the camera – see picture). Make sure the receiver is connected securely to the camera.

Audio Input Settings

The controls for setting the audio input of the microphones are found inside the LCD Monitor compartment. The controls are divided between CH 1 AND CH 2 settings and recording level thumbwheels, INPUT 1 and INPUT 2, and MONITOR

The CH 1 and CH 2 settings allow you to send audio from a selected microphone input to a specific audio channel. Typically, CH 1 is considered to be the left channel and CH 2 is the right. The settings allow users to set the camera’s internal (INT) to either or both channels. In addition the microphones that are attached to the INPUT 1 and INPUT 2 terminals can be sent to specific channels. 

Under INPUT, the user can select microphone options attached to the input terminals. For both INPUT 1 and INPUT 2, there are three microphone options:

  • LINE – allows you to connect the output from a sound board or other audio device.
  • MIC – this setting is used when connecting to a stick microphone or wireless
  • MIC+48V – this setting is used when connecting a microphone that requires phantom power, such as a shotgun microphone to the camera.

You adjust the recording levels for the

two channels manually or

automatically. When adjusting the

recording levels manually, make sure

that the audio bars, displayed in the

monitor/viewfinder, don’t peak in the

red, otherwise, the audio will become


BEST PRACTICE: Always wear headphones when recording. You must be able to monitor the quality of the audio, not just simply look at the meter to know that you’re recording sound. Headphones will help you hear for distortions, including unwanted static, cracks, pops and hissing sounds that could interfere with the audio. Without headphones, you’ll never know the quality of the audio.

As an example, when using the wireless microphone:

  • Plug the receiver into INPUT 2
  • Set CH 2 to INPUT 2 (you can leave CH 1 to INT so that you’re still recording with the camera's internal microphone at the same time you’re recording with the wireless.
  • Set the AUDIO INPUT for INPUT 2 to MIC
