Smallrig 3487 Forevala W60 Wireless Microphone 

Stereo Hi-Fi Sound - Equipped with a built-in professional-grade ARM Cortex-M4F Microprogrammed Control Unit (MCU), Digital Signal Processor (DSP), Radio Frequency Power Amplifier (RFPA), and Low Dropout Regulator (LDO), providing powerful computing power for superior digital signal transmission and 48kHz 16bits high-fidelity lossless sound quality.

• Dual-channel, low-latency wireless audio transmission, signal range of up to 100m (no obstacles)
• Long battery life of up to 8 hours on a single charge
• Professional and high-performance omni-directional condenser microphone for high-definition and high-quality recording
• Switch between mono and stereo; stereo recording and sound reproduction enhance post-editability
• Low cut function: eliminates low-frequency noise below 200Hz to make purer audio output
• Gain adjustment: input and output volume of TX-A and TX-B are partitioned and independently adjustable
• Three-screen display: power/signal/volume/low cut function all displayed on screens
• Plug and play, smart pairing

Up to 8 Hours of Nonstop Operation

The low power consumption transmitter (TX) and receiver (RX), coupled with high-capacity lithium-polymer batteries, ensure high-speed, high-sampling rate, pure sound quality recordings for up to 8 hours on a single charge (Data source: SmallRig Electrical Lab).

Excellent Audio and Video Synchronisation

Utilises 2.4G Adaptive Frequency Hopping technology, and has a built-in SMULL (Synchronise Multi-Node Ultra-Low-Latency) communication algorithm.  Sound Latency is as low as 10ms and stable transmission is possible up to 100m / 328ft away (in a barrier-free environment).

200Hz Noise Reduction for Crystal Clear Recordings

The one-touch Low-Cut Filter eliminates low-frequency noise below 200Hz (such as friction noise / current noise / outdoor background noise etc.)

Mono / Stereo Modes

Supports one-key switching between Mono / Stereo Modes, supports zone gain adjustment in stereo mode.

Three Separate LCD Displays

The receiver can view the status (recording mode / battery level / recording dynamics) of the transmitters in real time.

Compatible with Multiple Devices

Supports cameras / mobile phones / action cameras / tablets / voice recorders and other equipment
