there is no analog video associated with the new input, a message will be displayed on the component output.

Note

If both Standard and High Definition inputs are assigned, the Input Menu will display Video: (2). If only one is assigned, it will display the slot and offset it is assigned to. If neither are assigned, it will display Video: Unassigned.

Note

You can associate the same physical connector with more than a single input.

Sound Profile

One of the most powerful uses of the sound profile capability of the Nº40 is to associate a default sound profile with an input. You can always override this default profile, but used intelligently, this feature can largely automate the reconfiguring of the system to suit different situations. This will be discussed in more detail later, see �Advanced Features� on page 7-1 for more information. If you would like to automatically switch to a particular sound profile whenever you select the input you are defining, select it from the list of profiles provided here. Of course, you cannot select a profile that has not yet been defined; this is why the sound profile menu comes before the inputs menu. (Naturally, you can jump back and forth between the menus as needed to get the job done.)

Analog Input Offset

If you have an analog connection associated with the input you are defining, you can set an analog input offset that will be implemented for that connection whenever it is used. This adjustment serves two purposes: it allows you to match the perceived volume of all the analog sources to that of the digital sources in your system (which are normally already matched fairly closely); it also allows you to adjust the level of the incoming analog signal to prevent it from overloading the analog to digital converters. Doing either of these adjustments with any degree of accuracy will accomplish both ends. The Nº40 includes a state of the art analog to digital converter (ADC). Since all processing in the Nº40 is handled in the digital domain, analog signals must first be converted to digital form. It is extremely important to avoid overloading or �clipping� the ADC, since doing so results in a nasty burst of distortion that sounds similar to a power amplifier clipping. Unlike power amplifiers, this sort of clipping can occur at any volume level, since the ADC is being clipped well before the volume control in the signal path. Fortunately, the Nº40 can detect when its ADC is being clipped, and posts a notice to that effect in its front panel display and on the onscreen display. If you see such a message, you should turn down the input level on the Nº40 (which turns down the volume of the signal going into the ADC). You should also probably save this new
