This fully integrated, highly cost effective Sound Masking System is an ideal solution to commercial office building noise reduction. Designed specifically with medium sized office spaces and commercial environments in mind, this system makes a great addition to any cubicle divided space, conference room, reception area, or any area needing additional sound masking.

The installer friendly AtlasIED DT22 provides clear paging and background music in a labor saving package. Ideal for use in shopping malls, department stores, and anywhere large quantities of loudspeakers are to be utilized.

The AtlasIED DT22 2' x 2' drop-in loudspeaker system simplifies loudspeaker installation by providing an all in one loudspeaker package in acoustic ceiling grids. The system includes the loudspeaker/transformer, enclosure, and grille. Enjoy clear, crisp paging and background music from the installation friendly DT22 without compromising building cosmetics.

Small and compact, and engineered for reliability, the AtlasIED MA40G amplifier is the perfect choice for distributed business paging and background music (BGM) systems, and small to medium speech privacy systems. It provides 40W into a 70.7V/100V line and has three total inputs including a balanced mic/line input featuring phantom power and variable mute sensitivity control as well as two unbalanced, summing line level inputs. Additional features include Removable Level Controls with set it and forget it security cover, contact closure mute terminals, and a global (100VAC-240VAC) power supply. The MA series of amplifiers are part of a new line from AtlasIED that are designed from the ground up and include the important features professional installation personnel require to meet or exceed their customer's expectations.

The AtlasIED TSD-GPN1200 sound masking generator is perfectly suited for basic sound masking systems. The analog topology design eliminates repeating cycles commonly found in other manufactures low-cost digital designs.

The TSD-GPN1200 allows selection between pink or white noise sources and incorporates a variable balanced output to match input requirements of AtlasIED equalizers and amplifiers. In addition to the line level output, a 4W, 70V output is provided to power up to six masking loudspeakers tapped at .5W each.

A variable hi-cut filter with operating range between 1kHz and 8kHz at a slope of 6dB per octave supports equalization requirements for most basic Sound Masking systems. Both outputs may be used simultaneously allowing large zones to be addressed with external equalization and amplification while a smaller zone is powered by the internal 70.7V amplifier with spectrum control provided by the on board hi-cut filter.
