Figure 40. A Single-Supply, 2-Way Active Crossover
T he crossover example frequency of 500 Hz can be shifted
lower or higher by frequency scaling of either resistors or capaci-
tors. In configuring the circuit for other frequencies, comple-
mentary LP/HP action must be maintained between sections,
and component values within the sections must be in the same
ratio. T able II provides a design aid to adaptation, with sug-
gested standard component values for other frequencies.
