Signal Levels
The Pu n signal levels can be monitored between Set? and olume. These show a dB
full scale (dBFS) value, so +00dBFs is the max signal the Pu n can handle at that stage
in the Pu n, and this is normally a nega ve value. The more nega ve, the smaller it is.
The Pu n routes the signal in the follow way:
Input -> Adjustable Analog Gain -> ADC (Analog-Digital Converter) ->
DSP (Digital Signal Processing) -> DAC (Digital-Analog Converter) -> Output
If +00dBFS peak signals regularly occur at either the le or right ADC, lower the
PuYn's Gain.
If +00dBFS peak signals regularly occur at either the le or right DAC, lower the
PuYn's Gain or Volume.
The Select bu on can change between the Average and Peak signal mode. Peaks can
easily happen with vinyl pops, and these clip events don't harm the PuYn and are
handled gracefully and not set downstream. Any DAC clipping is handled in the DSP
¯oa ng point math and causes no issues other than small amounts of higher order
distor on. The main goal is to avoid distor on caused from constant clipping. For ref-
erence, -20dBFS to -10dBFS is a typical Average signal level range at the DAC.
