- Real time operating headroom shown as discrete parameters or a combined curve
- Curves display performance changes over time for accurate system evaluation
- Metering switchable for peak or average characteristics
- Unique colors for each curve allow simultaneous monitoring of multiple channels
The History Tab shows headroom graphs for critical amplifier and speaker parameters for a selected load and the amplifier channels driving it. The graphs extend four hours back in time and display the amount of headroom available for the given parameter. Both the peak and average values are shown for each two-minute sampling interval.
