Sigma AMP5 - 5-Channel 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.

CAN-Bus stands for "Controller Area Network (CAN) Bus".  Classé's implementation of CAN-Bus allows for communication and control between Classé components.  All you need is to connect the CAN-Bus port as a "daisy chain" and make sure the last unit connected has a "terminator" on the CAN-Bus out.

Note that some older Classé equipment may not recognize more recent Classé Models via CAN-Bus. In case of doubt, please contact Classé Techical Support.

The IR in and output port allow for an electrical IR signal to control the "standby" and "operate" mode on a Classé Amplifier.  This is not an infrared signal, but a electrical signal obtained by using standard IR receivers, distribution amplifiers, and emitters (available from your dealer) that will translate the remote’s flashes of infrared light into corresponding pulses of electricity.

Classé Amplifiers will consider the constant presence of a 5V-12V DC signal on the DC input as an "operate" signal.  The unit will go into standby when the DC voltage is absent.

This must be done manually, using the Front LED Standby button of the Sigma AMP.

1. The first step is to activate the "Configuration Mode" using the Front LED button:
   
   While holding the LED button depressed, plug in the AC power cord. Once the amber or green LED comes on, let go of the button (make sure you can actually see the light of the button, so put your finger halfway). Do not let go too quickly otherwise the unit will default to standard operation.  If you see an alternating Green and Amber LED, you have successfully entered the Configuration Mode.
2. Once in Configuration Mode, the LED indicates whether each feature is enabled (= solid) or disabled (= flashing).
   
   Wake on Network = Amber LED
   flashing = disabled, solid = enabled.
3. To change from flashing to solid, wait until the color lights up, then press the LED button once and let go. You have now changed the status.
4. In order to verify the new Status, wait until the LED passes by again.  It will now indicate the new Status.
5. To return to normal operation, simply disconnect and reconnect the AC Power Cord.

This must be done manually, using the Front LED Standby button of the Sigma AMP.

1. Enter the Configuration Mode using the procedure mentioned above in A1.
2. The Green LED indicates the Status of Auto Standby. Flashing = disabled.  Solid = enabled.
3. To change from solid to flashing, wait until the color lights up, then press the LED button once and let go. You have now changed the status.
4. Follow Steps 4 and 5 outlined above.

This must be done using the CAN-Bus feature of the attached Classé Sigma SSP or CT-SSP/SSP-800.

• Sigma SSP
  From the MENU, select STATUS > click RIght Arrow at the top > The CAN-Bus devices now show on screen > Select the unit
• CT-SSP/SSP-800
  From the MENU, select System Setup > Status > More > select unit > configuration.
