The Chat Attach is a specialized accessory designed for scaling ClearOne’s Chat 150 USB group speakerphones. By connecting two identical Chat 150 units using the Chat Attach cable and power supply, users can extend the audio pickup and clarity across larger meeting spaces—ideal for mid-size to large conference rooms.

This setup retains full-duplex communication—meaning conversation flows naturally without users talking over one another—and integrates ClearOne’s HDConference™ suite, which includes echo cancellation, noise reduction, automatic level controls, first-mic priority, and adaptive acoustic modeling. The linked speakerphones provide 360° microphone coverage (up to about 8 feet) and strong audio playback.
