1.1 Introduction
Congratulations on your purchase of the dbx 223s/223xs or 234s/234xs crossover. We are
confident you will find this crossover to be the finest product of its kind. We have taken
care to include all of the features you need to make your system sound its best. Some of the
features common to both the 234s/234xs and the 223s/223xs crossovers are:
• back panel switches for selecting the operating mode of the crossover.
• back panel switches indicating the selected range of crossover frequencies. Both of these
features have LED indicators on the front panel so you can see at a glance which mode
the unit is in.
• low frequency summed output designed specifically for mono subwoofer applications.
• phase invert switches on all outputs.
• individual level controls on every output.
We are sure you will agree that these crossovers are built to provide extremely high quality
frequency division for all your PA applications.
