Kramer 22-00010399 Audio Diode Analog to Analog Always Open No Microphone

Kramer 22-00010399 Audio Diode Features

The new HSL Audio Diode family of products connects a source (a PC usually) and an audio device (speaker/ headphone). The Audio Diode prevents attackers from exploiting audio-data leakage.

Unidirectional Flow The Audio Diode functions as a diode that forces audio signals from a PC to be unidirectional. This prevents hackers from manipulating a speaker/headphone to function as a microphone, for picking up surrounding conversations.

Low-Pass Filter All sounds passing through the Audio Diode go through a low-pass filter that restricts the audio frequencies to the range compatible with the human ear. This prevents hackers from attacking by broadcasting high-frequency signals to an external hacking device.

Features

• Unidirectional Audio Flow: Ensures audio signals flow only from the PC to the output device, preventing unauthorized audio capture.
• Low-Pass Filter: Limits audio frequencies to those detectable by humans, thwarting high-frequency hacking attempts.
• Secure Listening: Allows users to listen in on classified or sensitive conversations in secure environments.
• Network Transfer Capability: Enables data transfer from secure to unsecured networks, enhancing operational flexibility.
• Configurable Settings: Features push buttons to activate the speaker/headphone, with adjustable settings for call duration.
• LED Status Indicators: A bi-color (green and red) LED displays ON/OFF status and flickers before disconnection, ensuring user awareness.
• Single Event Detection: Detects press-and-release as a single event, preventing accidental activation from continuous button pressing.
