user preset to be monitored.
In
Normal Operational Mode
each press of the

cycles through the following sources:
Analog
,
AES1
(
unbalanced),
AES2
(
balanced
)
,
SD-SDI1
(or
HD-SDI1
), and
SD-SDI2
(or
HD-SDI2
). In models without
SDI
capability,
only the
Analog
and
AES
inputs are cycled through.
When
Preset Mode
is enabled (see
Preset Mode Enable
section on page
29
), each press of the
Input Button
cycles through
the
named presets
set up by the user (instead of cycling through the available inputs).

Pressed by itself, the

Φ
Button
enables the
Phase/Correlation Indicator
in the
LCD Display
. The
average
correlation (phase) for the selected channel pair is indicated by a stationary block in one of three positions on the
second line of the display. A moving block may also be present in these positions to indicate the
instantaneous
(short
time sample) phase correlation. The three positions are as follows:
Center:
Only one channel active or zero correlation between the two channels
Left (-):
Selected channels are
out-of-phase
(
-1
correlation maximum)
Right (+):
Selected channels are
in-phase
(
+1
correlation maximum)
Note:
With typical stereo program material, the moving block display is normal. With a single signal, or two completely
un
-
related signals selected for the speaker(s), no correlation information is available, so the phase indicator block will be at rest
in the
center
of the LCD. A mono
in-phase
signal fed to both right and left channels would result in the block being in the
right-most
position indicating complete correlation of the two signals.
