Technical specifications
3.1 Current/power draw and thermal dissipation
Measurement references
For all noise signals, the values are measured at the maximum level
just before any amplifier limiter activity (no Gain Reduction).
Noise CF 12 dB: Noise signal according to EIA-426-B with a
crest factor of 12 dB.
This represents the use case of live music or less compressed
recorded music.
Noise CF 9 dB: Noise signal according to EIA-426-B with a crest
factor of 9 dB.
This represents the use case of music with medium compression.
Noise CF 6 dB: Noise signal according to EIA-426-B with a crest
factor of 6 dB.
This represents the use case of heavily compressed music.
Sinus (100 ms): 1 kHz sine wave signal, 0 dBFS input level and
a duration of 1 s.
The RMS current value is calculated over a 100 ms time window.
This window is stepped in increments of 10 ms over the recording.
The resulting value is the highest current within a window of
100 ms.
