SYNCO G2(A2) 2.4GHz Wireless Lavalier Microphone System SYNCO G2 furthers the stability and articulation with Syncoder Encrypted Transmission Algorithm 2.0, which greatly improves the channel option principle and signal transmission capacity. It actively detects the current environment, then automatically switches and assigns the optimal frequencies with Frequency Hopping Spread Spectrum (FHSS) technique before conflicts occur. FHSS offers a broad frequency band to improve privacy, reduce interference, and increase signal capacity. With the advanced algorithm, SYNCO G2 provides secure, stable and quality audio within 492ft/150m (Line-Of-Sight) and 98ft/30m (Non-Line-Of-Sight) range. To restore the subtle changes in sound, SYNCO G2 coalesces low cut, gain control, and a real-time audio monitoring system. You have a larger adjustment range for various conditions.
