Description
The Atlas Sound TSD-GPN1200 sound masking generator is perfectly suited for basic sound
masking systems. The analog topology design eliminates repeating cycles commonly found in other
manufacture’s low cost digital designs.
The TSD-GPN1200 includes a selectable pink or white noise generator and incorporates a variable
balanced output to match input requirements of Atlas Sound equalizers and amplifiers.
In addition to the line level output, a 4W (70V Masking System) 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 4W
amplifier 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 amplifier with spectrum control from the internal high cut filter.
The TSD-GPN1200 is part of a full line of Atlas Sound Time Saving Devices. These compact
(1.5" x 4" x 2.75") units are designed to solve some of the common audio system problems in the
easiest and in the most efficient and cost-effective way. All models are made from high quality
components and include removable individual I/O connectors for quick and precise wiring, separate
ground terminals for all I/Os assuring secured connections, and removable level controls that can be
replaced with tamper-proof security covers. The TSDs are highly efficient and meet Energy Star™
standards as one 24V DC power supply (available separately) can power multiple Time Saving
Devices.
