ENC-powered Clear Audio for Efficient Team Coordination

Unparalleled Dual-Mic ENC

The Solidcom C1 Pro boasts unparalleled dual-mic ENC technology that delivers clear sound captured from challenging loud environments. Its directional main mic focuses precisely on the speaker’s voice range, and simultaneously, the omnidirectional secondary mic collects environmental noise from different directions as noise samples. The sound signal is processed with the advanced ENC algorithm, effectively cancelling the environmental noise and delivering crystal-clear sound quality.

Note: The ENC technology functions by removing the environmental noise at the speaker side, so that the listener can hear the speaker’s voice clearly.

150Hz–7kHz Wideband Audio with AEC

The Solidcom C1 Pro intercom system is capable of delivering authentic and clear sound even in the most demanding production environments. Its premium Acoustic Echo Cancellation (AEC) function effectively removes unwanted echo within the 150Hz to 7kHz frequency response range, bringing in more efficient teamwork.

Robust Wind Noise Removal

Troubled by wind noise in outdoor production environments? The Solidcom C1 Pro offers a versatile solution that prevents airflow from directly hitting the mic. With the Y5 felt paper designed for the main mic as the wind filter as well as the microphone cushion, you can enjoy complete peace of mind in production environments where wind noise is a major challenge.

ANNOUNCE for Emergencies

The Solidcom C1 Pro hub is designed with a one-button “ANNOUNCE” function for emergencies. By activating this function in an emergency, all headsets in the system are instantly muted, allowing the entire team to only hear the direct instructions or commands from the user of the wired hub headset.

Customizable and Expandable for Varying Team Sizes

The Solidcom C1 Pro is available in a variety of non-hub packages for accommodating team sizes ranging from 2 to 8 members. If A & B grouping and the ANNOUNCE function are desired, a hub (including a wired headset) can be easily incorporated into any number of headsets. A hub-based system supports a communication team with up to 9 members.

Note: A master headset cannot be used in a hub-based system.
