The SMG-40 Sound Masking Generator Keeps Office Conversations Private
Acoustic tiles, carpeting, and fabric-covered cubicles have helped to make the modern office a quiet place to work. But the lack of noise has the unintended effect of making even the smallest sound seem loud by comparison, distracting from the task at hand.

Full Description & Specifications
The Contemporary Research SMG-40 Sound Masking Generator has the power to drive over 30 25V plenum and ceiling speakers, 70V transformer, 4/8 ohm speakers, and over 100 Cambridge Qt® Emitters. Many masking generators use standard pink noise while the SMG-40 filtered noise is optimized for masking speech in real-world applications.
Housed in a compact metal enclosure, the amplifier can output 40W audio over two RJ-45 ports and a 3-pin Phoenix terminal for 25V, or 4/8 Ohm speakers and 70v transformer. A stereo Music input and level control is available for BGM applications. A contact closure input can mute the amplifier when activated.
