Sigma AMP MONO - Mono Power Amplifier

How to check the current Firmware of your Sigma AMP

• If the Sigma AMP is connected via CAN-Bus (to a SSP), you can check the installed Firmware Version using the Status Screen of your Classé Surround Sound Processor.
  
  
• If you have no CAN-Bus connection to verify the Firmware Version then we advise you update the Firmware using the Procedure below in any case.  It will take only a minute.

How to update  Firmware on a Sigma AMP (all models)

• download the latest Firmware package
• unzip the downloaded file on your local computer
• copy the unzipped file onto a new USB key.  This key must be empty.  The file must be located at the "root" level
• power off your Sigma AMP using the Power switch on the rear of the unit
• insert the USB stick in the front USB port
• Power on the Sigma AMP using the power switch in the rear of the unit
• the Firmware update will start automatically and will take less than a minute
• When finished the unit will go into Standby (solid red LED)

What to do when your Firmware Update fails

• simply power down the unit and remove the USB key, the unit will revert back to its previous Firmware Version when your power on again;
  
  Then what...?
  
  
  1. Our first suggestion is to try again using the same USB key;
  2. If the Update Fails once more, we suggest that you get a new, clean USB key and try again. We have seen updates fail because of fragmentation of the USB key, or because of vendor-specific key issues.
  3. If the Update still fails, we ask you to send us the APP.LOG and BOOT.LOG files that you will find on the USB Key:
     - insert the USB key into your local computer and open the USB key (file explorer)
     - you will notice that 2 LOG files have been written to the USB key.
     - Copy these log file to your local computer. 
     - Please send them to Classé Tech Support for further evaluation, with the Serial Number of the unit.
