Zoom f4 multitrack field recorder mixer xlr sd card recording microphone sound. XLR outputs not compatible with my Sony NXCAM I use for videography. Camera is looking for +4dbu and the XLR outputs on the recorder are -10dbv (or something of that nature). For that 1 reason, I cannot use this mixer. Never used in the field, only used in testing at home prior to realizing I needed a different device.
