High-gain Laser Direct Structuring (LDS) antennas ensure stable audio transmission free of all sorts of interference from up to 1000' away. The transmitter features a dual-interference design with a metallic mesh that protects against dust and 2.4 GHz, infrared, and RFI interference. The receiver is dual-channel and features an integrated camera-mount interface. A 3.5mm TRS output port records audio directly to your device of choice. Environmental noise cancellation minimizes frequency interference for improved vocal clarity. The LARK M2 captures 24-bit 48 kHz audio with a 70 dB signal-to-noise ratio and 115 dB SPL. Connect your LARK M2 system to the LarkSound App to adjust parameters like volume and noise cancellation, update firmware, or check real-time audio statusall from your iOS or Android compatible smartphone.
