Destination Routing Inputs Options Outputs eAMP1-8M Destination Outputs On the left of the Global Output Routing screen are listed the Destination Outputs. These are the outputs to which any input can be routed. They are as follows: 1. Speaker/Headphone: Selected inputs will be sent to the left and right speakers.
4. Volume Control: This setting determines whether each output pair is adjusted by the Volume Control knob. Speaker/Headphone outputs are always affected by the volume control knob, as are any outputs that are in Speaker Mix mode. Page 62 eAMP1-8M/16M...
What signal outputs can be controlled using the Global Output Routing feature? All the outputs on the eAMP1-8M/16M can be controlled using the Global Output Routing feature. This includes – Internal Speakers and Analog XLR outputs. How do I route whatever is being monitored to the XLR? Using Global Output Routing, you may route any signals to the XLR outputs.
Analog XLR. In this way, the internal speakers will always be muted, but the audio will appear on the Analog XLR outputs (for amplified external speakers). Make sure that the Speaker Mix checkbox selection is unchecked for Analog/XLR. Page 64 eAMP1-8M/16M...
In the Output Routing setting, for the Analog XLR outputs, keep the Volume Control checkbox unchecked and the Solo/Mute checkbox checked. This ensures that the Volume Control is not applied to the outputs, while the Solos/Mutes are. Page 65 eAMP1-8M/16M...
Preset Replication is available if the OPTe Package is purchased. This feature allows you to copy presets from a master unit to multiple eAMP1-8M/16M units. This can save a lot of setup time if multiple units all need basically the same setup.
Page 67
The progress of the Preset replication for each unit, as the Presets are being copied, will be displayed in the Process column. When all of the Presets have been copied to each of the selected units, you may leave this screen. Page 67 eAMP1-8M/16M...
8M/16M. Likewise, it can be used to import a Preset database from the computer hard drive into the eAMP1-8M/16M. In this way, a Preset configuration may be only devised once and then duplicated into all of the eAMP1-8M/16M units in a system, saving significant effort.
Import Configuration Use the following steps to copy the Preset configuration into the eAMP1-8M/16M: 1. Click the Browse button as shown in Figure 4-21 and select the Preset Tag you would like to import.
These tabs are explained in the following two sections. System Information This tab displays a variety of information about the eAMP1-8M/16M. It is shown in Figure 4-22. This information could be useful to view if you are contacting Wohler Technical Service.
This tab displays the license number for each of the modules or features in the eAMP1-8M/16M. It is shown in Figure 4-23. You will use this tab to enter any new license numbers that you purchase. Contact Wohler Sales to obtain new license numbers.
If you have any doubt as to whether you should perform a Factory Reset, do not click the Initiate Factory Reset button. Contact Wohler Technical Service for advice. Factory Reset will also reset your IP address to the default one. After a Note: Factory Reset, the IP Settings will need to be updated.

Introduction This chapter describes how to download a software update file to your computer, transfer it to a USB flash drive and install the updated into an eAMP1-8M/16M. Download the Software The eAMP1-8M/16M software update can be found at http://www.wohler.com, under Product Downloads on the Products >...
Local Update from the Front Panel Use the following steps to update the eAMP1-8M/16M software: 1. Copy the unzipped Wohler Update Package file(s) from your computer to the root directory (not inside of a folder) of a USB flash drive. It must be FAT32 file type, and does not need to be empty.
Page 76
After the software update starts, the text on the left screen will change periodically to indicate the progression of the upgrade. The upgrade may take 5 minutes or more, after which the eAMP1-8M/16M will restart. After the system has completed its restart cycle and is once again operational, you may then remove the flash drive.
USB flash drive. 2. Connect to the eAMP1-8M/16M with the Wohler Web GUI. Navigate to the System | System Update menu, as shown in Figure A-5.

Web GUI until the update process is complete. When it is complete, the eAMP1- 8M/16M will restart. Updating an eAMP1-8M/16M Remotely Use the following steps to update the eAMP1-8M/16M software: 1.
Page 80
3. At this point, wait for the update to complete. It may take several minutes, it is critical not to disturb the eAMP1-8M/16M or the Web GUI until the update process is complete. When it is complete, the eAMP1- 8M/16M will restart.
Use the following steps to update one or more eAMP1-8M/16M units remotely by transferring the software from a previously updated eAMP1-8M/16M: 1. If any of the eAMP1-8M/16M units that you intend to update remotely may be in use, contact the people using them and let them know what you will be doing.

Figure A-15 – System Update Progress 6. At this point, wait for each update to complete. It may take several minutes, it is critical not to disturb any of the eAMP1-8M/16M units or the until the update process is complete. When it is complete, each Web GUI eAMP1-8M/16M will restart.
If the OPTe Package is purchased, then the Application Program Interface (API) is available for use. This appendix discusses ways to use the API to allow third party equipment to remotely access options and settings of the eAMP1-8M/16M. It includes specific code examples for commonly used requests. The API uses JavaScript Object Notation (JSON) as its communication language.
