Level RMS
The units dBµ, dBV, dBSPL and V are selectable.
Distortion THD+N
The distortion measurement is carried out within the bandwidth 10 Hz...20 kHz.
The results are given in dB or in %.
Signal Balance
The signal balance field shows the matching deviation of the incoming signal
between pin 2 and pin 3 in %. The signal balance field indicates the following:
• Arrow in center: the input signal is balanced.
• Arrow out of center: linear indication of a balancing problem.
E.g. the arrow shifted to the left shows the signal level on pin 2 is higher than
on pin 3.
• Arrow at the left or right end: the signal balance error is 33% or higher.
33% corresponds to a difference of the signal level of 6 dB.
• 2UBAL-: indicates a signal only on pin 2 of the symmetrical XLR cable, no
signal at pin 3.
• -UBAL3: indicates a signal only on pin 3 of the symmetrical XLR cable, no
signal at pin 2.
Note: Use the adapter –20 dB for balanced input levels higher than 3.8 V
(unbalanced).
