1 Overview The SMS-FLAT loudspeaker is designed to generate the optimum masking sound in a tight space where a more standard loudspeaker wouldn’t fit. Equipped with two drivers in dipole configuration, the SMS-FLAT provides an effective loudspeaker in a very compact form factor.

3.2 Connecting the Speaker 1) Unscrew the cover plate to access the connector block: 2) Remove the connector block, connect the wires and put back the connector block in place. Use plenum rated cable and follow local regulations. Typical wire will be 18/2 FT4. If you connect more than one speaker, simply twist the wires in the same connector block.
3.3 Securing the Speaker Secure the speaker by fastening the mounting bracket to the building structure using screws (not supplied). Slide the speakers on the mounting bracket. Note: When mounting the speaker on a vertical surface, be sure to mount the bracket with the forks facing up to avoid the speaker from falling down.
3.4 Setting the Transformer Tap Remove the rubber cover from the tap knob. Adjust the tap setting using a flat head screwdriver: The recommended tap for most applications is 4W @ 25V. Some limitations may apply to the sound masking controller. See controller specifications for more details.
4 Raised Floor Application The SMS-FLAT speakers can also be used in a raised floor configuration where space is limited. Raised floor panels Since a raised floor panel has a high sound transmission loss, the sound power required to meet the sound masking target can be quite high, especially for low-frequency (bass) content.
