It is built for creators who need dependable audio without a complicated setup.

• Up to 100 m line-of-sight range with stable RF output at 10 mW
• OLED displays on transmitter and receiver for quick status checks
• Omnidirectional lavalier microphone included for natural voice pickup

• Powered by 2x AA batteries or USB-C DC 5V, with up to 8 hours of runtime

In daily use

Clip the transmitter to a belt or pocket, attach the lavalier, and mount the receiver on your camera shoe. The OLED screen shows battery level, channel, and signal strength at a glance. A 3.5 mm headphone jack on the receiver lets you monitor audio in real time, so you catch issues before they ruin a take. The included TRS and TRRS cables cover both camera and smartphone inputs.
