SYSTEM SETTINGS
THE SYSTEM SETTINGS MENU
• These are general settings which affect all Stages and overall
operation.
• The Harmony will generally operate satisfactorily with the default
settings. However, it is recommended that each of these settings be
checked on Startup to tune the Harmony to the particular system.
• From the main display, press the ADJUST/SELECT knob and release
it to reach the Settings display.
• Scroll down to <System Settings> and select it.
• The System Settings 1 menu will be shown.
SYSTEM SETTINGS 1
AUTO ROTATE Default - Time
• The Lead Stage will always be the first stage activated when there is
a call for output.
• Automatically rotating the Lead among the active stages promotes
more even wear on the Stages and can help prolong the life of each
unit.
• The Lead Stage is shown on the main display in brackets.
• The Harmony has three selections for rotating the Lead Stage. Each
is described below.
Manual
• If Manual is selected, the Lead Stage will not automatically rotate.
• In Manual, whichever stage is presently the Lead Stage will remain
the Lead Stage until there is a power failure. Then the Harmony will
revert back to the lowest Stage in Auto Mode (that is, A first, then
B, C, or D).
Time
• On power up, or any time the Harmony loses power, the Lead Stage
will be the lowest stage in Auto Mode (that is, A first, then B, C, or
D).
• If the default 24 hour rotation is used, at 2 am every morning, the
Lead Stage will change to the next stage in Auto Mode. Note: If you
do not set the system time (see pg. 21), the Harmony will assume it
was installed at 2 pm.
• If the Rotate Time is changed (see pg. 20), the Lead Stage will
change to the next stage in Auto Mode every time the Rotate Time
has elapsed. For example, with a 12 hour Rotate Time, the Lead Stage
will rotate from A to B after the first 12 hours of operation, and then
from B to C after the next 12 hours, and so on.
• The Lead Stage will always be the first stage brought on and
modulated when there is a call for output. As more output is needed,
additional Stages are added.
• When less output is needed, the additional Stages are turned off in
the reverse order of how they were added. For instance, if the
stages were added in the sequence A, B, and C, then they will be
turned off in the sequence C, B, and finally A.
