Record up to two people for mobile journalism or content creation applications to your USB-C mobile device using the blackLARK C1 DUO Wireless Microphone SystemfromHollyland. The system includes two transmitters with built-in, omnidirectional microphones and one dual-channel receiver—all with a compact form factor. Clips on the back of each transmitter allow you to attach them to the lapel of a shirt, while the plug-in receiver attaches directly to the USB-C port on your smartphone or tablet, which also supplies it with power.
Audio can be transmitted wirelessly from up to 656' away thanks to the LARK C1's 2.4 GHz auto frequency hopping technology. Integrated into each component's design are LED indicators to display power and connectivity statuses. Each transmitter features a built-in rechargeable battery that will power it for up to 8 hours. Noise cancellation technology can be toggled using the onboard controls and helps highlight vocals over ambient noise. Intuitive plug and play pairing allows you to use the system right out of the box. The free LarkSound app allows you to view the remaining transmitter battery time as a percentage and make volume, playback, and noise-cancellation adjustments.
