constant tone issue with some new iConnectAudio4+ units

We have had reports from some users who have recently bought iConnectAudio4+ units that their interface is producing a constant tone at around 2 kHz when it is switched on. After testing we have found that this issue only affects a small batch of units with serial numbers between 000011A7 and 0000139B and is because of a faulty firmware being loaded at the factory. It is not a hardware fault with the unit itself

If you have one of these units, the problem should be easily fixed by simply installing the latest beta firmware. Just follow this procedure to fix:
  1. Uninstall any version of iConfig older than 4.2.5
  2. Download iConfig 4.2.5 from https://www.iconnectivity.com/software/iconfig
  3. Download beta firmware for your device from https://www.iconnectivity.com/firmware (note this is a .MID file)
  4. Run iConfig 4.2.5, go to Device -> Upgrade Firmware From Local Drive and install the firmware file you just downloaded
  5. Your device should go into bootloader mode (flashing yellow lights on the front panel), install the firmware, and restart itself. 
  6. If not, check you are connected the correct USB port on your device (only one of the USB ports will work for firmware loading). Choose a different port and try again.
  7. When your device has reset, check under the Device Info tab in iConfig that the new firmware version has been installed. 
This should give you a pristine interface the way it was supposed to be :-)

We are very sorry for any inconvenience this may have caused anyone. Do let us know if you have one of the affected units and still have any issues after following the procedure above.
