 Section 3 - Rear Panel Operations

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.

When you are certain that the proper selections have been made, complete the steps 
described below and in the “234s/234xs or 223s/223xs Audio Connections” section on page 9.
