3.1 Rear Panel Operations
The mode switches on the back panel of the unit are used to select one of the three modes
of operation in the 234s/234xs and one of two modes of operation in the 223s/223xs. There
could be disastrous consequences if the crossover were improperly setup or the switches were
mistakenly pushed during the regular operation of a sound system. Therefore great care should
be taken when setting these switches. There is a mode diagram on the back panel to help you
understand at a glance how this is done. The following steps should be taken in setting up
your system:
• Know the loudspeaker manufacturer’s requirements regarding the amplification needs
of your particular speaker system. Follow the manufacturer’s guidelines carefully, as
dbx is not responsible for damage relating to improper setup or implementation of the
234s/234xs or the 223s/223xs.
• Without any audio or power connections in place, use the back panel switches on the
crossover to set it to the proper mode of operation; either stereo 2-way, stereo 3-way, or
mono 4-way for the 234s/234xs, or stereo 2-way or mono 3-way for the 223s/223xs.
• Use the literature that came with your speaker system to properly set up the mode of
operation and crossover frequencies to the manufacturer’s specifications.
• There is one of the four possible mode button combinations for the 234s/234xs which is
marked “not valid”. Be sure you have not selected this combination as the 234s/234xs
will not operate correctly in this mode.
