    Construction

  • Automotive:
    The 24V variant of the XA88 is compliant with automotive regulation
    EN/ECE R10 encompassing the requirements of EN 50498:2010.

    Loop Performance:
    The XA88 will enable an Audio Frequency Induction Loop system that meets the requirements of EN 60118-4:2006 to be created, if the system is specified, installed and commissioned in an appropriate manner, including observing Ampetronic instructions.

    Standards compliance to IEC 62489-1
    T14 amplifiers are designed to form part of a system which can meet all requirements of international loop performance standard IEC 60118-4, and relevant parts of BS 7594. To fully meet requirements of these standards, correct design, installation, commissioning and maintenance are required.

    Ampetronic drivers have CE and UL marks to all relevant safety and EMC standards.
