Wireless Remote Switch

Hollyland Solidcom C1 Pro is the world’s first wireless dual-mic environmental noise cancellation (ENC) intercom system! The sound is captured with a directional microphone with ENC switch, that uses a secondary microphone in the headphone listening to environmental noise from all directions. The signal is then processed with the advanced ENC algorithm to ensure crystal clear voice reproduction. The C1 Pro has been created for production teams working in noisy environments where exceptional communication clarity is crucial, including music festivals, sports events, TV & film set production etc. The C1 Pro line is also backwards compatible with the possibility to mix-and-match with standard C1 system headsets and hubs. Furthemore, the Colidcom C1 Pro features a Push-to-Talk (PTT) functionality with Talk/Mute button and indicator light, and a button long press momentary mode where pushing the button enables the talk mode, releasing enables mute. The Hollyland Solidcom C1 Pro is a full duplex wireless intercom operating in the 1.9 GHz band (DECT 6.0) with a range of up to 350 m (line-of-sight). By integrating all components into the headset, it offers maximum convenience and easy portability, without additional beltpacks or base stations. The headset weighs approx. 170 g and is supplied with a spare battery for continuous operation, with no dropouts. The Solidcom C1 Pro intercom offers audio transmission in the frequency range 150 Hz - 7 kHz, AEC (Acoustic Echo Cancellation) technology, directional microphone for ambient noise cancellation, additional omnidirectional microphone for ambient detection and Environmental Noise Cancellation (ENC; can be deactivated), Push-to-Talk operation, transmission encryption, etc. It comes in several variants as a set for teams of two to six.
