Automute disabled – Register x04h set to x60h. Reference voltage is 20.6 V. FFT size 16k.
Figure 17. Idle Noise FFT Spectrum (PBTL)
Channel separation is tested for two channels in a different package, channel 1 and channel 2. 4- Ω loads
are used for both channels. Channel 1 input signal is 0 dBFS; channel 2 is muted. Reference voltage is
20.7 Vrms
