The Extron SB 33 A is the industry's first adjustable-width sound bar for enhancing the audio experience in collaboration spaces. It features two 3” full-range drivers with a tuned port, powered by an ENERGY STAR qualified Extron Class D amplifier. Designed to mount under a display, the SB 33 A features an innovative adjustable width capability, allowing it to match the precise width of the display for a custom look. The center panel accommodates an internal webcam and can be configured for PTZ cameras using an optional shelf.  There is also an optional blank center grille for applications where no camera is required. The SB 33 A is compatible with the VCM series volume and mute controllers. The SB 33 A mounts to an included wall plate or to an optional VESA mounting kit for use with display mounts.

Adjustable Width

Since display bezel widths vary, the unique design of the SB 33 A allows its width to be adjusted during installation to precisely match the width of the display. Installed under a display, the SB 33 A provides a clean, custom look without the expense or extra time needed for a custom solution.

Camera Customization

Not all collaboration spaces serve the same function or have the same requirements, particularly when it comes to conferencing support. For some, a highly streamlined solution with a simple webcam meets the requirement. For others, a full PTZ camera is required to visually track individual conference participants. Still others are pure local collaboration spaces that require no conferencing at all or require an installed webcam to be blocked at will for security purposes. The SB 33 A meets all these needs through the use of its optional PTZ camera shelf, blank center grille, and standard webcam slot with a built-in door.

Configurable Mounting

A wall bracket is included, providing an easy way to flush mount the unit under a display. For installations involving an articulating mount or when the display is not directly mounted to a wall, an optional VESA mounting kit is available. When the SB 33 A is installed with the VESA mounting kit and an articulating mount, the sound bar and display move together as one unit.
