Atlas Sound TSD-GPN1200 – Gen 2 Sound Masking Generator

Product Overview

The Atlas Sound TSD-GPN1200 is a Generation 2 sound masking noise generator engineered for basic commercial sound masking systems that require speech privacy and acoustic comfort. This compact device produces pink noise output through a DSP-based topology that eliminates the repeating cycles found in lower-cost digital designs, making it a reliable choice for open-plan offices, private offices, and conference areas. Long-tail applications include Atlas TSD sound masking generator for commercial offices, pink noise generator for speech privacy systems, and 24VDC sound masking module for distributed audio racks.

Product Description

The TSD-GPN1200 delivers a pink noise signal as its masking source and provides a variable balanced output to match the input sensitivity requirements of AtlasIED amplifiers in the field. Its variable high-cut filter operates between 2kHz and 16kHz at a 6dB-per-octave rolloff slope, allowing technicians to shape the masking spectrum to suit the acoustic environment and the characteristics of the installed speakers. The remote level control feature accepts an optional AtlasIED ATMASKSC masking attenuator, enabling precise system-level adjustments in 1dB increments from a remote location without accessing the device directly. The non-fluctuation output design ensures consistent masking noise levels once the system is commissioned, which is critical for maintaining acoustic performance in occupied spaces. The TSD-GPN1200 operates from a 24VDC power supply sold separately, drawing only 250mA, and is compatible with any AtlasIED TSD power supply. Multiple TSD devices can share a single power supply, reducing overall installation cost. The compact 1.5" x 4" x 2.5" chassis can be deployed as a standalone unit or mounted using an optional TSD-RMK rack mount kit. AtlasIED provides a 36-month warranty on this product, reflecting its use in permanent commercial installations.

Key Features

• Gen 2 DSP Noise Topology — Eliminates repeating cycles common in low-cost digital designs for natural-sounding masking.
• Pink Noise Source — Spectrally shaped output matches the acoustic characteristics required by most commercial masking systems.
• Variable Balanced Output — Adjustable level matches the sensitivity requirements of any AtlasIED amplifier input.

Frequently Asked Questions

Q: What type of noise does the TSD-GPN1200 produce?

A: The TSD-GPN1200 produces pink noise, which has equal energy per octave and closely matches the spectral profile used in most commercial sound masking systems. Its Gen 2 DSP topology avoids the repeating cycles that can make noise perceptible in quiet environments.

Q: Does the TSD-GPN1200 include a power supply?

A: No. A 24VDC power supply is sold separately. The unit draws 250mA, so it is compatible with the TSD-PS24V500MA or TSD-PS24V2500MA. Use the AtlasIED TSD Power Calculator when combining multiple TSD devices on one supply.

Q: How is the remote level control implemented?

A: The TSD-GPN1200 includes a remote level control port designed for use with the AtlasIED ATMASKSC masking attenuator. This allows adjustments in 1dB steps from a remote location without opening the equipment enclosure.

Q: Can the hi-cut filter be adjusted after installation?

A: Yes. The variable hi-cut filter is adjustable between 2kHz and 16kHz, allowing post-installation tuning to match the frequency response of the installed speakers and the acoustic characteristics of the space.

Q: Can the TSD-GPN1200 be rack-mounted?

A: The unit can be used as a standalone device or rack-mounted using the optional TSD-RMK 1RU rack mount kit. The GPN1200K bundle includes the generator, power supply, and rack mount kit together.

Q: How many TSD-GPN1200 units can share a single power supply?

A: At 250mA per unit, a TSD-PS24V500MA (500mA) can power two units, and a TSD-PS24V2500MA (2500mA) can power up to ten. Always use the TSD Power Calculator to confirm total current draw for your specific configuration.

Q: What is the output level of the TSD-GPN1200?

A: The maximum balanced line output level is 500mV with a 300Ω balanced output impedance. The level is adjustable to match the input sensitivity of the connected amplifier.
