Description of change:

The New C Series firmware update on network models adds:

  • SNMP for status reporting and monitoring 
  • A priority input option
    Input 2 (mic/line or 100V) can now be used to override other inputs when active 
  • Tooltips to the web interface
  • Status reporting for configuration of alerts and notifications
  • and support for DHCP Option 61
  • The ability to assign a single channel amplifier to either phase for use of perimeter loop drivers as part of a larger multiloop installation e.g. theatre balconies 

All models now have:

  • HF Boost MLC option added to better optimise frequency response for systems where metal losses have caused a more significant high frequency attenuation.
  • An Input 250Hz low cut option added to the front panel of non-network drivers, to improve intelligibility by attenuation of lower frequencies when using a mic directly with the driver. 

Additional improvements:

  • Sleep and Standby mode improvements
    • Standby indicated by Amber flashing LED
    • Sleep is Green flashing
    • Return to home screen on front panel when returning from Standby
    • Standby maintained despite test tones or input signal
    • Change default Sleep time to 30 mins
    • Reliable recovery from Sleep
  • Wholesale Network revision
    • Improved compliance with RFC standards
    • Management of Static / DHCP / Link local IP slots
    • IP address added to front panel status page for easy reference
  • Website improvements
    • Power status – Active / Standby / Sleep – added to website ‘Status’ page
    • Error configuration / management improvements
    • Help Text added to all key features
  • Variable Speed fan – to enhance product lifespan
  • Various other bug fixes
