Impedance Test in Generator Mode
The MR-PRO measures phantom voltages and displays imped-
ances and the impedance balance in the SINEWAVE operating
mode. Using the SINEWAVE sinusoidal test signal, the MR-
PRO measures the load connected to the output between PIN
2 and 3 (RL=R2+R3). The measured values of R2 and R3 will
be displayed by selecting RL with the rotary wheel.
If only R2 or R3 can be measured, RL is replaced by R2 or R3
accordingly.
In the case of balanced connec-
tions (XLR), interference radiated onto
the receiver side will be eliminated.
For this to work there must be a balanced
impedance distribution on both signal lines.
In the case of unbalanced impedance dis-
tribution, signal interference could occur.
The MR-PRO allows you to test the connec-
tions for balance.
