An integrated 8-array omnidirectional microphone system provides long-range sound pickup from approximately 8 to 12 metres. Automatic gain control, echo cancellation, and intelligent noise filtering help improve audio capture during meetings and online collaboration.

30 W Built-In Stereo Speakers

Two built-in speakers provide 2.0-channel audio with a total front-facing power output of 30 W, consisting of 2 × 15 W speakers. The 150 Hz to 20 kHz frequency range supports presentations, training videos, video conferences, and multimedia playback.

Dual Wi-Fi 6 Connectivity
