11 Saving Your Work

The SDEC-3000 and SDEC-4000 DO NOT REQUIRE that you save at any time. When you are online and operating the unit your settings are being stored in protected memory at all times and no save process is required or possible. Saving your work is completely a safety copy in case anything happens to either the SDEC or your computer.

Once you have completed the calibration and the final subjective listening tests you can save your work. Two copies should be saved. The first is a copy on your computer that you can distribute to other installers or keep as a backup on your own computer incase anything happens to the SDEC. The second is a copy that will be kept on the SDEC itself that can be retrieved in case your copy becomes corrupted or lost.

11.1 Save a copy using SAVE AS

Once finished but still connected to the Ethernet Network go OFFLINE by clicking on the green check box labeled ONLINE. This will disconnect your software from actively controlling the unit. It is now possible to use Save As from the File menu and save a copy as any other Windows file can be saved.

12 Recalling Saved Settings

Recalling your settings assumes that you are using London Architect to open and control the SDEC. If you are using the web interface (version 1.01 of the design file or higher) you will not need to recall settings as the settings will automatically be recalled. Settings can be retrieved from a number of different ways. Please read below for the different options. The London Architect software will automatically check to match the settings in your software against the hardware and give you options when opening the file and going online.

Note: If you do not have a copy of the saved file and cannot recall from the device network DO NOT update the design file. You MUST have the same design file that was used to calibrate the system, even if it is not the saved file. Please contact JBL Synthesis Tech Support for more information if you have this problem.

12.1 Recalling from a Saved File

If you have the saved file from the London Architect software you can simply open it with London Architect and you will now have the same settings as before.

12.2 Recalling without a Saved File

You must have a copy of the same design file that you originally used to do the calibration, even if you have not a saved copy. This is the same file that is saved in the SDEC but all the settings are flat with no EQ or calibration settings saved. This is the file you would have received from JBL Synthesis or opened from the device network originally. Using this “blank” file to connect to the SDEC. When you first go online you will be prompted to select from synchronizing the settings from your computer software or synchronizing from the hardware device. Choosing hardware device will recall all the settings from the hardware and show them in the software on your computer.

12.3 Recalling from Network Device

If a copy of the file has been saved to the SDEC itself it can be recalled from the device. After opening the London Architect software go to File￿ Open from Network Device. You will be prompted for a password and user login if necessary and shown a list of available files to open.

11.2 Save to Network Device

Once finished but still connected to the Ethernet Network go OFFLINE by clicking on the green check box labeled ONLINE. This will disconnect your software from actively controlling the unit. You must first save the file to your computer using SAVE AS and name it a unique name for this install. It is now possible to use Save To Device Network from the File menu and save a copy to the SDEC itself. This can be retrieved by using the Open from Device Network menu explained below.
