The sensitivity level of the high- and low-pass outputs of the crossovers can be independently adjusted
from 0 dB to -7.5 dB in 0.5 dB increments. The maximum attenuation level of -7.5 dB will compensate for
an approximate 4 dB difference in sound pressure level (SPL) between the tweeter and the mid-
range/woofer drivers. The sensitivity is adjusted using the HighPass[3:0] and LowPass[3:0] bits in the
Sensitivity register. Note that these bits affect the sensitivity of both channel A and channel B high- and
low-pass outputs.
The 2-way crossover can be enabled by setting the En2Way bit in the Volume Cfg register.
