WebDec 14, 2024 · Typically, a topology filter encompasses most of an adapter's topology nodes, although other devices within the adapter might contain additional topology nodes. For example, a wave device, which is represented as a wave filter, might contain DAC ( KSNODETYPE_DAC) and ADC ( KSNODETYPE_ADC) nodes. Second-order Linkwitz–Riley crossovers (LR2) have a 12 dB/octave (40 dB/decade) slope. They can be realized by cascading two one-pole filters, or using a Sallen Key filter topology with a Q0 value of 0.5. There is a 180° phase difference between the low-pass and high-pass output of the filter, which can be corrected by inverting one signal. In loudspeakers this is usually done by reversing the polarity of one driver if the crossover is passive. For active crossovers inversion is u…
