Setting Input Defaults

Tip:

Programming a New On Screen Alias

3ADD 15 TO THE NUMBER OBTAINED IN STEP #2 AND SELECT THIS SUM IN THE SET DELAY MENU

For example, if your rear speakers are 7 feet closer to you than the front speakers, add 7 to 15 to get 22 msec, which is the optimum delay for your system. Use the volume +/– keys to set this value in the set delay menu.

4MAKE A NOTE OF THESE SETTINGS UNDER “YOUR SYSTEM SETTINGS” IN THE BACK OF THIS MANUAL

Having these settings handy will prove helpful should anyone ever tamper with your careful calibrations.

Don’t be overly concerned about this setting—by its very nature, it does not have to be exact. The goal is to delay the rear speakers enough to make them be per- ceived as secondary sources of sound, without introducing so much delay that they sound like echoes of the original. In most systems, anything from 20–25 msec or so will perform just fine.

Although not really necessary for proper operation of the Proceed PAV, the input defaults section of the setup menu allows you to customize certain aspects of your PAV’s behavior.

The video portion of the input defaults menu also tells the PAV whether a par- ticular video input is using the composite or the S-video connectors. This is im- portant because it necessitates a change in the way on screen messages are gen- erated. (If set incorrectly, the blue field against which the characters are normally displayed may be gray. No real harm is done, but you may wonder why the pic- ture keeps losing its color momentarily when on screen messages are displayed.)

Before adjusting your input defaults, we suggest turning the master volume down to a relatively low level on your PAV (since you will be using strong signals to calibrate the system’s input levels and don’t want to endanger your loudspeakers). Then place the PAV into either THX cinema or pro logic mode (which engages the reference level LED in the main display). The following sections outline the various input defaults you may customize.

You can go directly from normal operation to the input default menu for a partcular input by pressing and holding the input button for about five seconds. When finished, pressing menu once will take you back to normal operation without having to do any further navigation of the menu system.

The PAV allows you to re-name its inputs for the purposes of the on screen menus, for greater clarity and simplicity of subsequent use. These “aliases” (alter- native, on screen names) may be up to five characters long.
