d&b D6 Software - Manual (Page 25)

InpMonErr
A numerical value indicating the number of times the D6 has entered
the error condition "InpMonErr" due to an Input Monitoring fault,
possibly caused by a missing external pilot signal.
DSP Halt
A numerical value indicating the number of times the D6 has entered
the error condition "DSP Halt" due to an internal fault.
Temp. (Temperature Log)
Proportionate temperature ranges.
They display the proportion of "On Time" the D6 has been operated
within the temperature ranges listed.
Input Monitoring off Input Monitoring
According to the European Standard EN 60849 "Elektroakustische
Notfallwarnsysteme" (equivalent to international standard IEC 60849
"Sound Systems for Emergency Purposes") the complete signal chain
needs to be monitored. Therefore the "d&b Input Monitoring"
functionality allows the detection of an incoming pilot signal to be
inserted into the signal chain in front.
Important notes on Input Monitoring
Input Monitoring can supervise the D6 analog or digital inputs. It is not
linked to the channel input routing, therefore it is possible to monitor an
input connector while it is not routed to an amplifier channel.
Depending on the selected input mode of the D6 the following Input
Monitoring modes are functional:
D6 Input mode Analog Pilot Digital Pilot Digital Lock
analog Yes No No
digital Yes Yes Yes
Tab. 2: Input Monitoring modes depending on D6 Input mode
The submenus "Input A" and "Input B" within the "Input Monitoring"
menu are related to the D6's input connectors according to the
following conventions:
D6 input mode is set to "analog"
The analog input connectors INPUT A/B of the D6 can be monitored for
incoming pilot signals.
When setting the D6 to input mode analog it is not possible to monitor
the digital input or whether the digital input has locked to the incoming
digital audio signal (as indicated in the table above - Tab. 2) In this case
a error message "A/B: Input monitoring Fault” is given out on the LCD.
D6 input mode is set to "digital"
In this case "Input A/B" in the "Input Monitoring" menu are related to
the AES channel. The analog input connectors INPUT A/B or the
DIGITAL AES/EBU input connector of the D6 can be monitored for
incoming pilot signals or whether the digital input has locked to the
incoming digital audio signal (Clock).
Example:
The D6 input mode is set to digital while the analog input connectors
are monitored for incoming pilot signals (Analog Pilot). The program
signal is fed to the digital input while for emergency calls the D6 will be
switched (routed) to the analog inputs of the D6 and the program fed to
the digital input will be interrupted.
