ABSTRACT
Crossovers intended for sound reinforcement are often constructed so they can be used in several different modes. Figure 14.1 shows the block diagram of a stereo 2-way crossover that can be switched to act as a mono 3-way crossover, or as a 2-way crossover with a single mono LF output for a subwoofer. Alternatively, a crossover might be switchable between stereo 2-way and mono 3-way crossover, with a wholly separate mono subwoofer output always available.
