1UNDER THE INPUT DEFAULTS MENU FOR THE CHOSEN INPUT, SELECT OFFSET AND PRESS EITHER OF THE VOLUME +/– KEYS

You will see a screen which looks like the following:

INPUT DEFAULTS

OFFSET 0

2USING AN APPROPRIATE TEST SIGNAL ON THE SOURCE COMPONENT, ADJUST THE INPUT LEVEL OFFSET UNTIL THE REFERENCE LED IN THE MAIN DISPLAY JUST ILLUMINATES

Appropriate test signals may be found on: Chapter 5 of Lucasfilm’s WOW! laserdisc; Track 1 of the Stereophile Test CD; or copies of either of these sources made on your tape decks or VCRs. (Note that the meters of analog tape decks such as cassette decks should read -20 dB when recording and playing back this signal.) Using the volume +/– buttons, adjust the input level offset up and down as needed until you find the setting at which the LED first illuminates.

3PRESS ENTER TO SAVE YOUR NEW DEFAULT INPUT LEVEL OFFSET.

This setting will automatically be used whenever you select this input. You are, or course, still free to adjust it manually should you run across a re- cording which was made at an unusual level.

Repeat these programming steps in turn for any inputs which will be used in your system’s configuration.

The PAV also allows you to set up a preferred surround mode for each input, which will be engaged automatically whenever that input is selected. For ex- ample, you might want to use stereo surround for most of your music listening.

As such, it would make sense to set that as your default surround mode for your CD player and other music sources. Similarly, you would probably choose THX cinema as your default for a laserdisc player. By doing so, you will automatically be in the most appropriate surround mode the majority of the time, without hav- ing to pay any attention to it yourself.

Any surround mode may be assigned to each input. In addition, there is also a choice given for none, which will leave the PAV in whatever surround mode it happens to be in at the time of the input selection. (Note that none is not the same as surround off which will force the PAV into two-channel stereo operation.) When the PAV leaves the factory, all inputs use “none” as their default surround mode, which leaves the PAV in the same mode all the time until you change it manually.
