Just got the Sound Devices MixPre-3 Audio Recorder/Mixer and USB Audio Interface in today and did a quick unboxing for a friend. The clicking you hear is the lens auto focusing ( yes it sucks but oh well hit mute if it bothers you )
UPDATE: So with more research the external battery will not work properly with the MIXPRE3 or 6. You will need an external battery that has a USB-C output to it. I just got the Anker PowerCore+ 20100 USB-C [ Ссылка ]
MixPre-3: [ Ссылка ]
