The two-channel receiver clips to your camera shoe and features easy-access volume knobs, a 3.5mm headphone monitoring output, a 3.5mm line output, and an easy-to-read OLED screen that shows the connection and battery status of all three units along with metering for audio levels.

The system uses automatic frequency selection with FHSS (Frequency Hopping Spread Spectrum) technology in the 2.4 GHz bandwidth to ensure a clean signal without interference or dropouts at a range of to 328′ line of sight and 65′ with limited obstacles. The receiver also supports switchable safety, stereo, and mono modes for different configurations and a low latency rate of 5ms.

Both the transmitters and the receiver feature built-in rechargeable batteries. The transmitters will each run up to 4 hours, while the receiver offers up to 7.5 hours of operating time; this means that for single-person shoots, the second transmitter can be used to extend your shooting time if necessary. The included storage and transport case automatically pairs the components and recharges them in 2.5 hours using its USB input port.

A USB cable, 3.5mm TRS audio cable, 3.5mm TRRS cable, two furry windscreens for the lavalier mics, and a storage bag are also supplied with the Lark 150. The system can be expanded with additional transmitters and receivers (available separately) to accommodate up to 8 wireless mics on set at one time.
