The AtlasIED TSD-GPN1200 Sound Masking Generator provides a flexible solution for commercial sound masking and speech privacy applications. Designed for offices, conference rooms, medical facilities, and other professional environments, this compact analog noise generator produces consistent background sound to help reduce the intelligibility of nearby conversations and minimize distracting speech.
Unlike basic digital generators that may repeat short noise patterns, the TSD-GPN1200 uses an analog noise generation design with selectable pink or white noise. This provides a continuous, non-repeating masking signal for properly designed sound masking systems.
The TSD-GPN1200 features both a balanced line-level output and an integrated 4-watt, 70.7V amplified output, allowing it to support small masking speaker zones directly or feed compatible external amplifiers for larger installations. Both outputs can operate simultaneously, providing additional flexibility when designing sound masking systems with multiple coverage requirements.
A variable high-cut filter, adjustable output levels, and compact AtlasIED Time Saving Devices (TSD) Series construction make the TSD-GPN1200 a practical choice for basic commercial sound masking installations.
Features and Benefits
Selectable Pink and White Noise Generation
The TSD-GPN1200 provides selectable pink or white noise sources to accommodate different sound masking requirements.
Its analog noise generation circuitry produces a continuous, non-repeating signal, helping maintain consistent background masking sound without audible looping.
Built-In 4W, 70.7V Amplifier
An integrated 4-watt, 70.7V amplifier output allows the TSD-GPN1200 to power a small zone of compatible constant-voltage masking loudspeakers without requiring a separate power amplifier.
For example, the output can support up to six masking speakers tapped at 0.5W each, provided the total connected speaker load remains within the amplifier's rated capacity.
This makes the unit useful for small offices, private workspaces, and localized sound masking installations.
Balanced Line-Level Output for Larger Systems
The TSD-GPN1200 includes a variable balanced line-level output for connection to compatible external amplifiers, equalizers, and other sound masking equipment.
This allows the generator to serve as a noise source for larger distributed sound masking systems.
Simultaneous Line and Amplified Outputs
Both the balanced line output and the internal 70.7V amplified output can operate simultaneously.
Installers can use an external amplifier for larger masking areas while using the built-in amplifier for a smaller nearby speaker zone.
Adjustable High-Cut Filtering
A variable high-cut filter allows the masking signal's high-frequency content to be adjusted to suit the installation.
This provides additional flexibility when tailoring background masking sound to the room's acoustic characteristics.
Line Output EQ and Level Bypass
Rear-panel switches provide additional configuration flexibility, including selection of pink or white noise and line-output EQ and level routing.
These controls allow installers to adapt the generator to different system configurations.
Compact Installation Design
The compact TSD Series enclosure is suitable for standalone installation or optional rack mounting.
Its small size makes it convenient for commercial audio equipment cabinets and installations where space is limited.
External 24V DC Power Supply
The TSD-GPN1200 requires an external 24V DC power supply rated for its 250mA current requirement.
The power supply is sold separately. For installations using multiple TSD devices, the total current requirement should be calculated before selecting a shared power supply.
