F11-2 Wireless Lavalier Microphone

The F11-2 Dual Wireless Lavalier Microphone system is an affordable, entry-level audio tool built specifically for mobile content creators. Below is an in-depth breakdown of its technical specifications, features, and settings:

Technical Specifications

Transmission Technology: 2.4GHz digital frequency protocol for stable, real-time sync with approximately 9ms ultra-low latency.
Operating Range: Offers up to 20 to 30 meters (65–100 feet) of barrier-free wireless transmission.
Polar Pattern: Omnidirectional (360-degree high-sensitivity sound capture).
Battery Performance: Built-in rechargeable batteries delivering 6 to 10 hours of continuous runtime per full charge via USB Type-C.

Key Features & Design

3-in-1 Universal Receiver: The single compact receiver contains three distinct hardware outputs: a Lightning plug for older iPhones, a USB Type-C plug for modern Android/iOS devices, and a 3.5mm TRS audio jack for DSLR cameras, laptops, and field recorders.
Clip-On Furry Windshields: Includes removable furry "deadcat" wind muffs (visible in the image) designed to dramatically cut out wind hiss and ambient air currents during outdoor shoots.
True Plug-and-Play: Operates completely driver-free. It pairs automatically as soon as the units are switched on, completely bypassing the need for dedicated mobile apps or Bluetooth pairing settings.

On-Device Controls & Audio Modes

The transmitters (TX clips) typically feature a power/mode toggle button alongside side-mounted volume controls:

Acoustic Mode: Standard, flat audio transmission without heavy electronic alteration.
DSP Smart Noise Reduction: Active filtering that isolates human vocals and aggressively suppresses persistent background noise (like traffic or fan hum).
Reverb Mode: Adds a simulated spatial echo/reverberation effect to the voice feed, popular for live streaming music, karaoke, or dramatic audio.
