Tannoy QFLEX User Manual page 28

The Logs area contains graphs of events against time, recording events over a period of up to three days. Since the
loudspeaker cannot record any events whilst powered-off, breaks in a log due to power-downs are indicated by a
discontinuity symbol '||' in the log. The events recorded are: Thermal, which is the used thermal capacity, Amplifier
Protect Gain, which is a measure of how much the loudspeaker is 'dimming' itself in order to protect itself from potential
damage, Driver Protection, which is a measure of how much the loudspeaker is 'dimming' itself in order to protect the
drivers from damage and Supply, which shows how the mains power voltage compares with nominal voltage. The data
in a log can be exported by right-clicking on the log to launch a context menu, and selecting "copy log data to clipboard".
The data could then be pasted into a spreadsheet for further analysis. Your dealer may ask you to do this is you have
experienced a problem. Note that in addition to showing amplifier protection due to over-heating, the Amp Protection log
will also show protection of individual amplifiers if they attempt to drive into an open circuit (if a driver has 'blown'). This
will be shown as a protection gain of approximately -9dB.
Power Save
At the bottom left hand corner of the control panel there is a power save button. Activating this button will shut down
the amplifier into a lower-power standby mode. The DSP section remains active. If you set the Power Save control to
anything other than Manual, the loudspeaker will automatically go into power-save mode after a period without any audio
signal, the time being set by this control. Whenever a signal is applied in this mode, the loudspeaker will rapidly wake-up.
You can change the view to the MonIcon panel by clicking the "<<" button.
