oversmp
This oversamples the signal going to the output meters to estimate the intersample peaks.
When on, the output meters will attempt to show the signal level after the DA converter and its
reconstruction filter.
Some poor quality reproduction systems don’t have enough headroom to handle analog signal
levels exceeding the equivalent of 0dBFS without distortion. Oversampled metering can be
used to predict such excessive levels. At this point, you can reduce the PSP Xenon output to
avoid them.
calibration buttons
The buttons under the calib label activate the pink noise generator for K-system speaker calib-
ration. The RMS level of the noise depends on which K-System scale is chosen. You can
choose to generate pink noise in the Left, Right, or Left+Right channels, depending on which
button you select.
PSP Xenon Operation Manual
Note: When you engage the oversampling option for the output meters, the signal level
displayed will only be an estimate. The actual level after the digital-to-audio converter
(DAC) will depend on the DAC reconstruction filter design, which there is no way for PSP
Xenon to determine.
TIP: If you engage the envelope detector oversampling mode, the envelope detector will
calculate the intersample peaks, and automatically compensate for them by applying the
requisite amount of gain reduction. This way, if you also oversample the output meters,
you can verify that absolutely no intersample peaks will exceed 0dBFS. This feature, by
the way, is unique to the PSP Xenon limiter!
