The two built-in XLR Terminals with independent audio level control on the XH G1S helps you to record audio at as high a level as your video. They provide phantom power and 3.5mm microphone and headphone terminals. With independent audio level control, you'll be in better command over the sound you record. You can simultaneously use the built-in microphone of the XH G1S and the XLR input, with individual sensitivity settings for each channel. The XLR sensitivity setting is selectable, from -12dB through +12dB. Line output level switching is provided, along with an audio volume lock to help prevent variations in the recorded sound.
