SOFTWARE INSTALLATION Place the installation CD into the CD drive. The XTD-680 Setup Screen will appear. To continue with the installation, choose “Next >”. If this is the first time setting up and installing an XTD-680, it is recommended that the precaution be taken of turning down the gain of the stage speaker amplifiers to a low level and turning OFF the amplifiers for the surrounds and subwoofer. A shortcut to the installation program will be placed on your desktop.
XTD-680 CROSSOVER SETUP Connect to the XTD-680 using the connect icon. Upon connection to the XTD-680, the window at the bottom right of the main screen changes from Select “Biamp” or “Triamp”, to The software starts, by default, in Triamp. If you wish to switch to Biamp, a warning window appears prompting you to change the speaker. When connected, the system will automatically mute the stage channels only at this time. Clicking on the “Default Triamp” button will bring up a Speaker Library.
In the “Speaker Library” window, use the pulldown to select the speakers. You may load channels by checking the boxes in the library window. When you have selected the channels you want, click “OK” to close the “Speaker Library” window. At this time, the settings you selected are loaded into the XTD680 and will be reflected in the display and the data at the bottom of the display. You may un-mute the system and audio should be present. This would be a good time to do a Disconnect and select “Save”.
