signal balance: This indicates the deviation from level-match of the
incoming balanced signal between pin 2 and pin 3 in percent (%).
The position of the arrow indicates the following:
• Arrow in center, the input signal is balanced.
• Arrow out of center, linear indication of a balancing problem, e.g.
arrow moves left nearer to the number 2 shows the signal level
on pin 2 is higher than on pin 3.
• Left or right end, the signal balance error is 33% or higher. 33%
equals a difference in the signal level of 6 dB.
• UNBAL, the signal balance symbol changes to UNBAL at the
signal balance error exceeding 90%.
result and unit: Level RMS. The units dBu, dBV, V are selectable.
Bargraph: The bargraph provides an analog display of the RMS level.
The scaling may be controlled automatically or manually.
• Select manual (M) or automatic (A) scaling by the bargraph zoom
