But first... A Word on Our Crossovers
The multiband crossovers in the AERO.mobile consist of second order Linkwitz Reilly
style filters that are hard coded to specific frequencies. As the processing required for tele-
vision applications is not as aggressive as other mediums, little advantage can be gained
from changing these values, and the remainder of the processing relies on these character-
istics remaining constant.
For reference, the crossover frequencies are:
• Band 1 (Low Bass): 20 Hz - 60 Hz
• Band 2 (Mid Bass): 30 Hz - 200 Hz
• Band 3 (Low Mid): 170 Hz - 1.15 kHz
• Band 4 (High Mid): 950 Hz - 6.1 kHz
• Band 5 (Brilliance): 5.2 kHz - 24 kHz
