SB 33 A Series • Setup Guide
Product Description
The SB 33 A speaker is an under-the-display powered soundbar speaker for use in small-to-medium conference rooms. It
features two 3" full range speaker drivers driven by an internal amplifier module. The SB 33 A accepts analog and unbalanced
stereo input signals. Three individually buffered inputs are available so three separate sources can be connected without altering
performance.
The SB 33 A speaker enclosure is adjustable to match the width of the display and is mounted under the display. It features
an adjustable shelf to accommodate the mounting of a web cam or small conferencing camera. The SB 33 A is offered in six
different sizes to accommodate screen sizes from 46" to 100" (117 - 254 cm), as shown in the table below.
