Audio Performance & Control
An advanced ATS3031 audio chip enables high-quality 48 kHz / 24-bit recording with built-in auto-limiting for consistent, distortion-free sound. The system features three selectable noise reduction modes, five-level gain adjustment, and nine EQ presets, including general, rich, bright, male, female, singing, guitar, violin, and ambient profiles.
Three mixing modes allow users to switch between mono, stereo, and safety track recording, offering greater flexibility during post-production.
Connectivity & Power
The USB-C plug-in receiver draws power directly from a connected mobile device and includes a pass-through port for simultaneous device charging. The camera-mount receiver features a 3.5mm TRS output for direct connection to cameras and other compatible equipment.
Each transmitter delivers up to 8 hours of operation on a single charge, while the included charging case boosts total system runtime to more than 40 hours, making it ideal for long shooting days.
