Detection Time
The maximum time in which a loudspeaker malfunction will be detected
by the system. The interval of the pilot signals is derived from this
parameter.

Calibrate Now The LF Driver menu serves as an example. The same menu is also
available for the HF and/or MF Driver.
Notes: All settings (except for "Last-Err") are determined during
the Calibration process. Only experienced users should
edit the following settings.

Definition of values:
Min
Lower limit of the impedance window which is set to –20 % by default.
Max
Upper limit of the impedance window which is set to +30 % by default.
Calibration
The impedance reference values derived from the calibration.
Last Mon
Impedances detected during the last measurement.
Last Check
Impedances detected during the last System Check (see also section
System Check on page 15).
Last Error
Last impedance values determined that led to an impedance error.
These values are kept even after acknowledgment of the error
message. They are only overwritten when another error occurs. A
calibration resets them to 0.
Pilot Freq.
Test frequency of the pilot signal for the respective driver.
Pilot Level
Reference level of the pilot signal derived from the calibration
procedure.
Threshold
Large signal threshold. If the output signal exceeds this voltage level
during the measurement, the tolerance limits for this particular
measurement are increased in order to compensate for the reduced
accuracy.
