Deity V-Mic D3 Pro Shotgun Microphone - Like New. Used a number of times. I have 2 of them and need to let one go. It charges thru USB-C and lasts a long time. When plugged into the camera, it is in standby mode until the camera is turned on, Great power saving feature. --------- The World's Only Microphone with a Stepless Gain Knob|: The V-Mic D3 Pro features a +20dB step-less analog gain adjustment dial. On each side of the dial the V-Mic D3 Pro features a bump guard that helps prevent the dial from being accidentally rotated. The +20dB of gain is added on a linear scale so you can dial in the exact amount of gain you need for the shot. Broadcast Quality Sound|: Superior off-axis sound performance. Low noise circuitry, Extremely Low Distortion THD (<0.1%), High-grade SNR (max. 84dB @-24dB sensitivity), 14mm Prepolarized Condensor Capsule. Smart 3.5mm TRS/TRRS Mic Output|: Out-of-the-box the V-Mic D3 Pro is compatible with DSLRs, Camcorders, Smartphones, Handy Recorders, Laptop, Bodypack Transmitters and Tablets. Please Note that some iOS devices require Apple's Lightning to 3.5 mm Headphone Jack Adapter(NOT Included). 75/150Hz Low Cut Filters|: Instead of a switch that is sunken into the frame that's hard to toggle, the D3 Pro does it all with a single button on top of the unit. With two levels of low cut the V-Mic D3 Pro is ready for even the windiest day. Intelligent Power On/Off|: The D3 Pro is ready in Stand-By-Mode and automatically goes into Run-Mode when the camera or device turns on. When the recording device is turned off, the D3 pro will automatically shut down after 15 minutes of standby to save power.
