Contact Microphone

AT880b
  • Surface contact piezo microphone
  • Can be used for multi-purpose such as underwater and flat vibration. The piezoelectric sensing device is housed in a waterproof metal case
  • Phantom powered with internal preamp for clear sound even with low impedance inputs and long cable connections
  • Permanent 25m cable and built-in dedicated power module for microphone
  • Aluminum cutting case with corrosion and water resistance, the housing provides sensitive vibration conductivity
  • Low profile design, can be installed in small and confined spaces for concealment
  • Equipped with mounting holes can be fixed with screws for security

    The AT880b is a waterproof Contact Microphone. It is suitable for sound pickup underwater or collecting the sound of objects vibrating from a flat surface.
    There is a high-sensitivity piezoelectric sensor inside, which is installed in a sturdy aluminum case with good corrosion resistance and waterproof performance. The aluminum case of the AT880b is thin in design, with a thickness of 10mm. It can be placed in small and narrow spaces for operation and can be fixed and installed with screws.
    The microphone is equipped with a 25m long cable, which is convenient for long-distance installation. AT880b has a built-in preamplifier, which can deliver clear signals over long distances, even when using equipment with low-impedance inputs.
    The AT880b microphone requires 48V DC phantom power for operation.
    Exposure of the microphone too high temperatures may result in a gradual and permanent reduction in output level. Avoid leaving the microphone in the open sun or in areas where temperatures exceed 43°C for extended periods.
