When you plug the V-Mic D3 or D3 Pro into the 3.5mm microphone jack of a recording device the microphone’s microprocessor shakes hands with the device. In most instances, this means you won’t need any adapter cables, although there are some exceptions. Here is a list of devices that are INCOMPATIBLE. Late-model iOS devices will require the Apple Lightning to 3.5 mm Headphone Jack Adapter. Google Pixel 2, 2 XL, 3, and 3 XL require a USB-C Headphone Adapter. GoPro Hero 1, 2, 3, 3+, 4, 4+Black, 5 Black, 5 Session, and 6 need a USB to microphone adapter. Sony FS5 / FS5 ii, FS7, Z90, Canon XA-10, XA-11, XA-15, XA-20, XA-25, XA-30, XA-35, C100, C300, and C500 require the D-XLR adapter. However, note that the lists suggest some devices are compatible whereas several users have reported some issues. One such problem is the Zoom H1n. Using the supplied TRRS cable the microphone may not appear to register with the device. One solution is to pull the cable out of the H1n slightly. However, it appears swapping the supplied cable for a third party TRS cable solves the problem. This is also the case for some Tascam recorders; Blackmagic BMPCC, BMPCC4k, Micro Studio Camera 4, and Micro Cinema Camera; Olympus E-M1X, E-M1ii, E-M1, E-M5ii, E-M5iii, and E-M10ii cameras. If you wish to connect a D3/D3 Pro to a Zoom H4n pro use the D-XLR adapter and turn on the phantom power.
