1.8.2 Center Frequency
Figure 13 shows the four possible center frequencies 10k, 12.5k, 15k and 17.5kHz.
Figure 13. Treble Center Frequencies @ Gain = 15dB
1.9 Speaker Attenuator
Due to practical aspects the steps in the speaker-attenuators are not linear over the full range. At attenuations
more than 24dB the steps increase from 1.5dB to 10dB (please see data byte specification).
1.10 Subwoofer Attenuator
The Subwoofer output is a single ended stereo output. The attenuator is exactly the same like the other speak-
ers.
