The SMS-STR is a 25-volt system loudspeaker designed to generate the optimum masking sound for a variety of ceiling conditions. This sound masking speaker is equipped with a 5″ (13 cm) driver installed in a sealed enclosure.
The design is ideal in open structure ceiling configurations since the speaker, terminal and switch will be hidden when the speaker is hung from the deck. It can also be installed above suspended ceilings in typical sound masking installations. A rotary switch allows quick adjustment of the output level with 4W, 2W, 1W, ½W, ¼W power available at 25V. The sound masking speaker is also compatible with 70V systems with 8W, 4W, and 2W, adjustment available.
