Description
The KAC-SPK-40 USB-powered audio bar is a conference audio solution designed to deliver clear speech capture and natural playback. It provides integrated stereo speakers and a subwoofer to maintain voice clarity across medium to large rooms. The system is certified for Microsoft Teams and Zoom Rooms which ensures predictable interoperability and call quality.
The unit includes two satellite microphones each fitted with 6m cables and providing coverage up to 10m to capture participants across a broad table or meeting area. Built-in DSP performs echo cancellation and noise suppression to maintain intelligible speech in mixed-office environments. Onboard controls include power, mute, Bluetooth, and volume up/down for quick local adjustments.
Audio performance is specified with loudness up to 100dB and power output of 20+20W delivered through four speaker units. The speaker frequency response covers 250Hz to 20KHz while microphone response covers 300Hz to 8KHz to prioritize voice frequencies. The system supports Bluetooth 5.0 audio codecs including A2DP, SBC, MPEG-4 and AAC for wireless connectivity.
Connectivity options include USB 2.0 via a USB-C connector for plug-and-play PC connections and analog output jacks that support daisy chaining to extend audio output. Bluetooth 5.0 enables direct audio streaming from mobile devices while the Teams and Zoom Rooms certifications ensure platform-level compatibility. Mounting options include tabletop standalone placement, wall mounting, or TV mounting to fit varied room layouts.
The KAC-SPK-40 is suited to meeting rooms, training spaces and huddle areas where clear two-way audio is required. It captures multiple speakers across the table and provides reliable playback so remote attendees remain engaged. The included satellite microphones and onboard DSP reduce the need for additional audio processing and simplify system design.
Installation and day-to-day use focus on simplicity and reliability – the USB-C connection supports plug-and-play operation and the physical buttons deliver immediate control without software. The bar is compact and light enough for easy mounting or tabletop placement and ships with options to support wall or TV attachment. Build quality and tested certifications make it a practical option for integrated AV deployments.
