RDL ST-NG1 White and Pink Noise Generator

For secure sound masking and surveillance privacy, the Radio Design Labs ST-NG1 noise generator delivers truly random analog white and pink noise to protect conversations and support accurate audio testing. As a Pro Sound Masking Generator from Radio Design Labs, the ST-NG1 produces broadband noise spanning 20 Hz to 20 kHz with amplitude-limiting circuitry that preserves at least 20 dB of natural variation while preventing damaging peak excursions. Because the ST-NG1 uses analog randomness rather than predictable digital patterns, it resists decoding by advanced intelligence or signal-analysis tools—making it a preferred choice for counter-intelligence, security, and monitoring deployments. Small and versatile, the unit offers mic- and line-level outputs for easy integration with amplifiers, audio systems, or surveillance monitoring racks. For installations exposed to high RF environments (Wi-Fi, transmitters), mount the ST-NG1 in an STS-RF1 shielded chassis to maintain signal integrity. Backed by a 3-year limited warranty and U.S. design, the ST-NG1 is an efficient, reliable component for engineered sound masking and secure audio applications—contact sales or add it to your system build today.

• Delivers truly random analog white and pink noise across 20 Hz–20 kHz to preserve speech privacy and improve masking performance
• Amplitude-limiting preserves at least 20 dB of dynamic variation while preventing extreme peaks for more consistent system behavior
• Mic and line-level outputs make integration with existing amplifiers, paging systems, or monitoring gear quick and flexible
• Compact, stick-on form factor (3" x 1.6" x 0.7") for discreet installation or mounting in shielded STS-RF1 chassis when RF immunity is required
• Ideal for security, surveillance, and counter-intelligence applications where non-repetitive, un-decodable noise is essential
