Signal Balance Error
The signal balance error reects the deviation from the perfect
balance status. No signal balance error indicates that the absolute
levels at XLR-pin 2 and pin 3 relative to pin 1 (ground) are identical
and opposite in polarity.

Bargraph with Scaling Information
In the BALANCE mode, the signal balance error is shown in a numerical
value, which is the deviation from the optimum in percent.
Balance Indicator: The direction of the deviation is indicated by the
arrows like 2 < 3 or 2 > 3, whereby the numbers 2 and 3 represent
the signal at XLR-pin 2 and pin 3.
In the Level, THD+N and Polarity (electrical input only) measurement
function, the Minilyzer permanently monitors the balance of the input
signal by a graphical indicator. This enables e.g. to check whether
cable connections are made correctly.
Bargraph: The bargraph shows an analog display of the signal
balance error. The scaling may be controlled automatically or
manually.
• Select manual (M) or automatic (A) scaling by the bargraph zoom
mode eld.
• Within the manual scaling press the left/right keys to scroll through
the actual range or the up/down keys to increase or decrease the
range (sensitivity) of the bargraph scale.
• Press enter to conrm your setting.
