T Series Default Configuration: Total.zip

This file contains the default configuration of a T Series unit following a factory reset. This can be used to restore a unit back to its default configuration in the event of a problem, e.g. in case inadvertent setting of the Ethernet parameters prevents access to the web interface.

Please note this file must be downloaded, extracted (unzipped) and copied to the T14-1 via its USB port. See the ‘Firmware / Web / Config / VoIP USB Upload instructions‘ document for guidance on how to use this file.

Note that restoring the default configuration will not reset the driver name, user passwords or VoIP unlock status.

C Series v1.2.zip


  •  alp.bin
  • cwebsite.bin

Description of change:

  • Switchable low cut filter added on both inputs with a networked amplifier – for applications where a microphone is plugged directly into the input. This is applied to the input, so does not affect test signals. Web configurable only. Default = off
  • DC output can be configured to flag faults with a networked amplifier. Web configurable only. Default = no error reporting (12V DC output)
  • Website enhancements:
    • Scaling on Compression & Current meters
    • Hidden channel B & current offset for single channel models
    • Added control of new features as detailed below
  • Improved management of settings restore to ensure compatibility with older units and enhance reliability.
  • Greater network security
    • Digest authentication
    • Monitoring and blacklisting multiple failed login attempts,
    • Stricter password rules
    • Telnet user authentication.

Note: Network security revisions may require adjustments to other systems which have been configured to communicate with C-series units – e.g. Telnet authentication. Please amend your systems as necessary.

  • Improved handling of GUI (front panel menu).
  • Improved handling of ‘Local Link’ network connection.
  • Support for up to 4 simultaneous website interface users
  • Fixes an issue on some units where output current is indicated without signal being delivered. In some extreme cases this causes a red screen start-up error “Loop A/B function test high over current’.
  • Enables upload of all files by USB power cycle.
