nal going into the ADC). You should also probably save this new setting as the default setting for that input, which will save you from running into this problem again—unless you later play something that is even louder. (In which case, you simply repeat the process outlined below.)

1TURN THE MASTER VOLUME CONTROL ON THE AVP2 DOWN

When the analog to digital converter clips, it distorts the waveform much as a power amplifier does when it clips. This is both unpleasant to hear and potentially dangerous to speakers at high volumes. Turn the volume down to a quiet, but still audible level just to be on the safe side, but so you can still hear what you are doing.

2PLAY THE LOUDEST SELECTION YOU CAN FIND ON THE ANALOG SOURCE IN QUESTION

Mind you, you are not playing this “loud section” loudly: keep it quiet, but play the biggest musical crescendo or movie explosion available on the source at hand.

3PRESS INPUT LEVEL ON THE FRONT PANEL OF THE AVP2 AND RAISE/ LOWER THE INPUT LEVEL WITH THE VOLUME KNOB UNTIL THE DISPLAY JUST READS “ADC CLIPPING”; THEN LOWER THE INPUT LEVEL BY 1-2 DB.

The goal here is to give yourself just a little “headroom” in case the next recording you play is a bit louder than the one you are using for this ad- justment. Note that some source components may have lower-than-normal output voltages, in which case you will end up “turning up” the input level setting to compensate.

4CONTINUE TO MONITOR THE RECORDING THROUGH ONE OR TWO MORE LOUD PASSAGES TO ENSURE THAT THE ADC DOES NOT CLIP; SAVE THE NEW DEFAULT VALUE BY PRESSING AND HOLDING THE INPUT LEVEL BUTTON

When you press and hold the input level button on the AVP2, the current value for the input level adjustment is automatically entered as the default input level setting for the currently selected analog source. (You can check this for yourself by going into the define button menu for that input, and checking the analog connection.) Whenever you select this input in the fu- ture, this setting will be loaded for you to protect against harsh-sounding ADC overload.

When you are all done defining how you want to us the nine input buttons on the AVP2, you may discover that you have some input connectors on the rear that are as yet unused. Since different people require different complements of con- nectors; we provide some redundant ones to ensure that everyone was likely to have what they needed. As a result, the AVP2 has nine input buttons, but fifteen audio inputs (eight analog pairs plus seven digital inputs of various types).

If you have additional sources beyond the nine most commonly used ones that you would also like to have as part of your AVP2-based system, you can access “virtual input buttons” via the more button (and by cycling through the defined inputs on the remote control).
