Mode 11 : AD values of the fader test. "FDR AD"
• Mode for displaying the AD values of the faders on the FL display for confirmation
When this mode is entered, “FDR AD” is displayed at the top of the FL display and the TAP key lights.
• Mode 11 consists of 5 pages for indicating the values of 5 faders.
The pages can be changed by pressing the BEAT

,
d
button.
When the groups are switched, the name of the
V
R at the top of the group list is displayed at the bottom of the FL display
and its AD value is displayed in the middle.
• The maximum amplitude value among AD conversion values for a fader being tested can be confirmed on each page of
this mode. The value is expressed with the number of segments lit at the bottom of the FL display. The measurement
procedure is as indicated below.
Set the fader you wish to test to a desired position then press the EFFECT CUE key to start measurement. To reset, press
the EFFECT CUE key again. During measurement, the maximum amplitude value will be continuously displayed.
The EFFECT CUE key is lit during measurement and goes dark when reset.
Details on the amplitude value display are shown in the figures below.
An amplitude value in the range of ±1 to ±7 with regard to the
V
R value at the beginning of measurement is displayed.
For a value greater than +7 or less than -7, all the 7 segments are lit.

The
V
Rs can be set to any position during measurement. Possible symptoms are shown below.
• The volume changes arbitrarily.
• Interrupted sound leakage occurs even if the volume is decreased to the minimum at the fader.
• The MIDI signal is output even if the corresponding
V
R is not operated.
• For operation check of a fader after replacement
