Automatic Calibration
This is the easiest way to set the input level for any source. It lets the advanced circuitry of the 7.0 do most of the work
for you. Unless you have specific requirements, this is the option to choose.
1. At the “Source Edit - Input Level Adjust” the “
Î
“ indicator should point toward “Auto Adjust”. (If it is not, press “
Ï
“
to move it up.) Press “Select” to move to the next menu.
2. The 7.0 will now take a few minutes to adjust the input level setting to match the output of the source machine. You
will be able to tell that the process is underway by The movement of the on screen slider bar and changes in the two
digit readout in the center of the screen and on the front panel display are indications that the calibration process is
underway. (Figure #xxa {on screen menu} and figure #xxb {two line display} ). During the process, the front panel LED
indicators on the front panel’s input level display will rise or fall. When the level is adjusted to the correct setting, the
green LEDs on the scale will flash at the “0db” indicator on the level scale.
NOTE:
To set a good baseline reference for the system, we suggest that the first component adjusted is your
laser disc player, if available. Use the THX “WOW!” disc supplied with the 7.0, and play the Test Signal on Side Two,
Chapter Five. If necessary, set your player to repeat the section so that there is sufficient time to properly calibrate the
system. Once the level has been set to this standard, the unit will operate properly with other program materials. Other
test discs, such as the Stereophile Magazine Test CD, may be used provided that a full range, full level signal is
played.
If the output level of the source machine is outside the range of the 7.0’s adjustment capabilities, either too high or too
low, a “Failure” message will appear(Figure #xx). This indicates that the source should be checks. See the Trouble
Shoot Guide in Appendix #xx for suggestions, or consult your dealer or installer for assistance. The inability to properly
calibrate the input level does not necessarily indicate a problem with the 7.0, as improper source output level may be
caused by a number of situations. It may also indicate that a manual calibration is needed.
When a level adjustment is successfully completed, the menu screen will return to the “Input Level Adjust” screen”.
Press “Exit/OK” to return to the “Source Edit” menu.
Manual Calibration
If you prefer to set the input levels yourself, or if a manual calibration is needed as the result of repeated failure
messages when attempting to calibrate the input levels automatically, follow the steps outlined below.
1. At the “Source Edit - Input Level Adjust” press “
Ð
“ so that the on screen “
Î
“ indicator is pointing toward “Manual
Adjust”. Press “Select” to move to the next screen.
2. The on screen display will show a slider bar as well as a two digit indication of the level setting. (figure #xx) At this
point turn on the source machine, and put it into play. Make certain that the program material is representative of the
type that will normally be played. For example, if this machine will typically play classical music, use a classical
selection. The same holds true if the machine will typically play action movies, heavy metal, jazz or popular music. The
selection need not be exact, but the closer the piece used during the input adjustment is to the type that will typically
be used, the more accurate the process will be. Note that unless the source machine is connected to the Citation 7.0
using an output jack with variable audio level, the actual volume setting is not relevant to the process.
3. Adjust the input level using the “
Ï
“ and “
Ð
“ buttons on the remote until the green LED indicators on the front panel
level control flash at the ”0db” mark. (Figure #xx, as used above). During the adjustment, you will see the slider bar on
the on screen display move left and right, and the numerical readout will change in reaction to the remote commands.
