In the EARS (Enhanced Ambience Retrieval System) Surround Mode, a realistic level of ambience of surround sound is added to a normal stereo source such as a CD or FM radio.
Surround Mode Off switches to normal Stereo operation.
NOTE: When using Digital Audio Input 3, the Surround Mode Off is selected, the analogue inputs will be selected. Therefore, ensure that the analogue outputs of the digital sources are connected as well to the same input the Digital Audio input has been assigned to.
As an additional convenience feature, your T770 memorises which surround mode you have used with the given input selection. When you next select that input, your T770 will automatically choose the same Surround mode again.

20. MULTI SOURCE
The NAD T770 allows you to change source and alter volume for another room by remote control, independently from the main listening room. This means you could be enjoying a DVD in Dolby Digital Surround Mode CD in the main room and somebody else to a radio broadcast in another room at the same time.

NOTES: As it is possible to use the Multi Source facility independent from the main listening room, an extra remote control handset can be useful. Your NAD dealer can advise you regarding the availability.
With the Multi Source facility in use, the source indicated in the main display for the main listening room can be recorded from.
ON SCREEN DISPLAY (OSD)
The NAD T770 is equipped with an elaborate On Screen Display facility (OSD). As the OSD is an essential tool to set up the various parameters for Surround sound correctly it is recommended that you connect your monitor or television to the T770.
For 230V versions only; not on 120V (North American versions): Depending on your source and/or the television system used you must first select the correct video system. If the OSD rolls over the screen you must select another system: PAL or NTSC.
•While pressing the Memory button (No. 14), press the Video 1 input selector button (No.6) repeatedly until the desired system is shown in the display area.
•If your television and your sources are
The OSD can be engaged by pressing one of the four cursor buttons on the remote control (No. 9). The main menu will appear (see Fig. 6).
Use the cursors buttons on the remote control to navigate, select
the desired menu and options. The 
and 
buttons are used to navigate and select an option (indicated by highlighting
the available option), the 
and 
buttons to change a setting from the highlighted section. Selecting “EXIT” from the Main menu will switch the OSD off. Selecting “EXIT” from any of the other menus takes you to the previous menu.
The OSD menu are at maximum three “layers” deep; this means that from the main menu (layer 1) you can select a sub menu (layer 2), from which you can again select a submenu (layer 3). The number of starts left and right of the menu header indicates which layer is displayed; 1 star for layer 1, 2 stars for layer 2, 3 stars for layer 3.
There are various ways in which the OSD can appear and function:
•From the Main menu select and enter the “Screen Setup” menu (see Fig. 7).
•Select “Superimpose = ON so that the OSD is superimposed over the video signal received from the T770 input selector. By selecting “OFF” the OSD will always be displayed with a solid blue background.
•Select “Temporary Display = ON” if you wish to see the OSD confirming each time an operation is performed for 5 seconds (such as volume change, different input selected, etc). By selecting “OFF” the OSD will only be shown when calling up the Main menu.
