PROSAFE Standard \u2013 Acoustic Safe<\/h2>\n

Protect sensitive conversations from mobile phone recording<\/h3>\n

The PROSAFE Standard Acoustic Safe<\/strong> is designed to protect confidential meetings and conversations from unauthorized audio recording through mobile phones, voice recorders, dictaphones and other devices equipped with microphones.<\/p>\n

By placing mobile phones and recording devices inside the acoustic safe and activating the integrated noise generator, the PROSAFE Standard creates an acoustic environment that makes it difficult for the devices’ microphones to capture intelligible speech.<\/p>\n

With a capacity for up to six mobile phones<\/strong>, the PROSAFE Standard is suitable for board meetings, management meetings, confidential negotiations, security-sensitive environments and other situations where sensitive information must remain within the room.<\/p>\n

Acoustic protection<\/h3>\n

The PROSAFE Standard combines acoustic isolation with active acoustic jamming. It provides:<\/p>\n

    \n
  • 35 dB acoustic attenuation<\/strong><\/li>\n
  • 50 dB acoustic jamming inside the box<\/strong><\/li>\n
  • Multiple selectable noise and sound patterns<\/li>\n
  • Smooth adjustment of the noise level via a control knob<\/li>\n
  • 350 mW output power<\/strong><\/li>\n
  • 36 \u03a9 \/ 500 mW loudspeaker<\/li>\n<\/ul>\n

    The integrated acoustic generator provides several types of signals, including:<\/p>\n

      \n
    • White noise \u2013 2 types<\/strong><\/li>\n
    • Speech-like noise \u2013 2 types<\/strong><\/li>\n
    • Metronome \u2013 2 types<\/strong><\/li>\n
    • Rhythmic sound with different frequencies \u2013 1 type<\/strong><\/li>\n
    • Combined mode \u2013 four different noises alternating sequentially<\/strong><\/li>\n<\/ul>\n

      The different sound modes allow the system to be adapted to different acoustic protection and testing requirements.<\/p>\n

      Designed for confidential environments<\/h3>\n

      The PROSAFE Standard allows mobile phones to remain in the meeting room while their microphones are acoustically protected. Users can therefore keep their devices nearby rather than leaving them outside the room or removing their batteries.<\/p>\n

      The system is designed for use during:<\/p>\n

        \n
      • Board and management meetings<\/li>\n
      • Confidential negotiations<\/li>\n
      • Strategic discussions<\/li>\n
      • Sensitive business meetings<\/li>\n
      • Security-sensitive environments<\/li>\n
      • Meetings involving confidential or classified information<\/li>\n<\/ul>\n

        Capacity and configuration<\/h3>\n

        The standard PROSAFE accommodates up to six mobile phones<\/strong> and can optionally be equipped with individual compartments for each device.<\/p>\n

        The standard external dimensions are:<\/p>\n

        33 \u00d7 24 \u00d7 15 cm<\/strong><\/p>\n

        The internal dimensions are:<\/p>\n

        23 \u00d7 19 \u00d7 12 cm<\/strong><\/p>\n

        The safe is available with a standard solid lid, while a transparent lid<\/strong> is available as an optional modification. USB and USB-C charging outputs are also available as options.<\/p>\n

        Optional EMI shielding<\/h3>\n

        For applications where protection against wireless communication is also required, the PROSAFE Standard can be supplied with optional electromagnetic (EMI) shielding<\/strong>.<\/p>\n

        The EMI-shielded configuration is designed to prevent the devices inside from maintaining connections to mobile networks, Wi-Fi and Bluetooth. Selcom specifies approximately 35 dB attenuation across 400 MHz\u20136500 MHz<\/strong> for the shielded configuration.<\/p>\n

        The standard acoustic model itself does not perform radio jamming<\/strong>; EMI shielding is an optional modification.<\/p>\n

        Power and charging<\/h3>\n

        The PROSAFE Standard can be powered using an external 12 V power supply<\/strong> or a 9 V 6F22 non-rechargeable battery<\/strong>.<\/p>\n

        Battery operation provides:<\/p>\n

          \n
        • At maximum noise level:<\/strong> \u2265 5 hours<\/li>\n
        • At minimum noise level:<\/strong> > 10 hours<\/li>\n<\/ul>\n

          Optional USB outputs are available with:<\/p>\n

          USB-A<\/strong><\/p>\n

            \n
          • 5 V \/ 3 A<\/li>\n
          • 9 V \/ 2 A<\/li>\n
          • 12 V \/ 1.5 A<\/li>\n<\/ul>\n

            USB-C<\/strong><\/p>\n

              \n
            • 5 V \/ 3 A<\/li>\n
            • 9 V \/ 2.22 A<\/li>\n
            • 12 V \/ 1.67 A<\/li>\n<\/ul>\n
