The GPN1200K is a compact sound masking generator kit designed for basic sound masking applications in offices, medical facilities, and other environments where speech privacy and noise control are important. The kit includes the AtlasIED TSD-GPN1200 generation 2 sound masking generator, TSD-PS24V250MA 24VDC power supply, and TSD-RMK 1RU rack mount kit. The generator uses digital signal processing (DSP) to produce a non-repeating pink noise signal, eliminating the repeating cycles commonly found in lower-cost digital noise generators.
The TSD-GPN1200 features an adjustable balanced line output for connection to compatible AtlasIED amplifiers and other commercial audio equipment. A variable high-cut filter, adjustable from 2 kHz to 16 kHz with a 6 dB-per-octave slope, allows installers to tailor the masking signal to the acoustic requirements of the space. The generator also supports remote level control through the optional AtlasIED ATMASKSC masking attenuator, which provides adjustments in 1 dB increments. The ATMASKSC is sold separately, and an external amplifier and masking loudspeakers are required for a complete sound masking installation.
The included TSD-PS24V250MA power supply provides 24VDC power from a universal 100-240VAC input. The TSD-RMK features a black brushed aluminum 19" rack panel that occupies one rack space and supports up to four compatible TSD Series modules. The rack kit includes three blank filler panels for unused positions, providing a compact mounting solution for the sound masking generator.
