Crestron UC-SB1


UC Video Conference Smart Soundbar

A sleek and stylish soundbar comprising a high‑performance conferencing speakerphone in one front‑of‑room device. Installs cleanly beneath the room display, and interfaces with a computer via USB. Includes connectivity for an external USB camera (not included).


The Crestron® UC Video Conference Smart Soundbar (UC-SB1) is a front‑of‑room device that eliminates the need to install additional microphones or speakers in a conference space. Mounted on the wall or placed on a credenza beneath the room display(s), the smart soundbar looks great and sounds even better in a small to medium‑sized meeting space.

High‑powered stereo speakers, adaptive beamforming microphone, and advanced digital signal processing deliver exceptional full‑duplex speakerphone performance with highly intelligible, echo‑free voice clarity. A USB camera can be connected via a USB 3.0 port on the rear panel.

NOTE: See also model UC‑SB1‑CAM for a similar solution with built‑in camera.

USB Speakerphone
The UC-SB1 is a high‑performance AEC‑enabled speakerphone. A USB camera can also be connected for a full video conferencing solution. The soundbar integrates with a computer running UC conferencing or web collaboration software, and also supports presentation of computer‑based AV content. A single USB 3.0 (2.0 compatible) connection provides a plug‑and‑play interface to a computer.

The soundbar behaves like most USB Audio Class devices, enabling use as a speaker and microphone for all types of multimedia applications running on a computer. Even if you’re not on a call, you can use the smart soundbar to share content with everyone in the room, or make a professional recording of the meeting.

Superb Sound Quality
The soundbar facilitates conversations with exceptional audio fidelity and pickup. Its integrated 180° far‑field microphone array faithfully captures voices throughout the room using adaptive beamforming technology. Its high‑powered, two‑way stereo speakers produce full, rich and real sounding audio. High‑performance AEC technology achieves transparent full‑duplex performance free of distracting echo or noise. Additional digital signal processing assures optimal sound quality for an immersive experience.

USB Camera Input
The UC-SB1 includes a USB 3.0 camera port to accommodate an external USB camera. Connect the camera to the soundbar to facilitate full audio and video connectivity to a computer through a single USB interface.

Enhanced Functionality
The UC-SB1 integrates seamlessly with a wide variety of computer‑based UC platforms. Plug‑and‑play USB connectivity enables control of the soundbar through the computer without requiring extra software, remotes, or a control system. The computer detects the soundbar connection automatically, and the soundbar responds when a conference call is started, speaker volume is adjusted, or the speaker or mic is muted. On the front of the soundbar, operational status is displayed by a multicolor LED status bar that illuminates as the volume is increased, and changes colors to indicate connection and mute status.

Analog Audio Input & Output
Additional audio connectivity is provided through unbalanced stereo analog input and output jacks on the rear panel. The input accommodates a line‑level audio source, which feeds to the internal amplifier and speakers with no volume control or other signal processing. The output is provided to feed an assistive listening system, and carries the same audio signal as the soundbar speakers.

Easy Installation
The integral hinged mounting bracket attaches easily to a wall surface using four screws. A total of eight mounting keyholes, arranged in 2 in. (51 mm) increments, accommodates wall stud spacing from 12 to 24 in. (305 to 610 mm). The mounting bracket allows the soundbar to be tipped forward for full access to the rear panel connections. Once installed and connected, the soundbar is held upright magnetically for normal operation. Alternately, the soundbar can be placed on a shelf or credenza. Optimal results are achieved by positioning the unit at ear/face height when seated. A single 100‑240 VAC outlet is required to power the unit.
