Hollyland Solidcom C1 Pro 3S full duplex ENC wireless intercom system with 3 headsets is the first system with dual microphone Environmental Noise Cancellation (ENC) technology that is incredibly lightweight and easy to use. This next-generation headset system features advanced DECT 6.0 technology, wideband audio range from 150Hz to 7kHz, and reliable LOS communication range up to 350m. The main directional microphone focuses precisely on the speaker’s vocal range, and at the same time, the secondary omnidirectional microphone picks up ambient noise from different directions as noise samples. The audio signal is processed with the advanced ENC algorithm, which effectively cancels ambient noise and provides crystal-clear sound quality. The Solidcom C1 Pro 3S is able to deliver authentic and clear sound even in the most demanding production environments. Its AEC (Acoustic Echo Cancellation) function effectively removes unwanted echo in the 150Hz to 7kHz frequency range, making teamwork more efficient. Your team can stay connected and move freely in a large space at important events, such as TV and film productions, live shows and events, and more. Operating in the 1.9GHz band with a dual-antenna design scheme for each headset, the full duplex ENC wireless intercom system with 3 headsets enables interference-free communication stability and clarity, with double the user capacity on the communication channel.
