The signal levels for each channel, displayed in yellow in the factory pre-
sets, can be presented in two distinct modes, depending on the preset
confi guration used. The traditional mode is the Quasi-Peakmeter (PPM),
using one of the common scales such as DIN, British or Nordic. Alterna-
tively, the single channel signal levels can be displayed using the newly
developed True Peak scale conforming to the most recent standards. True
Peak measurements have been introduced to make sure that high-level
audio signals cannot produce unwanted artifacts even when processing
them in a codec for data reduction, in a sample rate converter or a D/A
converter. For codec processing, the EBU R128 recommends a maxi-
EN
mum level of –3 dBTP. For all other applications, it recommends a maxi-
mum level of –1 dBTP.
The loudness bargraphs, displayed in cyan in the factory presets, show
the momentary loudness values for each channel using an integration
time of 400 ms.
