How to Check and Update Firmware

How to check the current Firmware of your Delta II Series Amplifier

  • The first option is through CAN-Bus. In that case, the amplifier must be connected to another Classé unit that has a TFT Touch Screen (like the SSP-800 or Sigma SSP). Press MENU > STATUS > MORE to view a list of CAN-Bus devices in the system. Select the amplifier and press SELECT > STATUS to view the current version. If the amplifier does not show up on the CAN-Bus list it should be updated.

  • The current Firmware can also be checked through a Classé Diagnostic Utility called Delta_CT_User_Interface_Installer.  As it name states, it allows you to access a Delta II amplifier (like this model) through a PC-based interface.  Please note that the Utility is only available for PC, due to limitations imposed by the Communications module.

Is a Firmware Update important?

Yes, a Delta II Amplifier Firmware Update solve issues that are found "in the field". Improvements can range from increasing the span of time between filter cleaning warnings, to important adjustments in soft start timings and shut down timings.

How to update Delta II Series Amplifier Firmware

This Firmware update must be transferred from a local Windows PC to the unit using the “Classé Amploader 3.5” utility. The Classé Amploader 3.5 utility is a small standalone application that can run from your computer's Desktop or your Program Files folder. It is included in the ZIP archive.

In most cases there are TWO software components to update: The so-called "Front Panel" (which holds the operating software to the unit) as well as the "Heat Sink" (which deals with equal temperature, and other Heat Sink considerations),  

Both must be updated. Make sure to update the Front Panel Software FIRST, prior to updating the Heatsink Software.

Home Automation

All Delta II amplifiers can be controlled via CAN-Bus, DC Trigger (in-out), IR in-out and via RS232.  The latter is available via a DB-9 connector on the rear panel.

IR Remote Control Codes

All Delta II Amplifiers can be controlled using RS232, a protocol used by Home Automation Systems like Crestron, Control 4, etc. Delta II Amplifiers are equipped with a DB-9 connector.
