The mode switches on the back panel of the unit are used to select one of the three modes of operation in the 234/234XL and one of two modes of operation in the 223/223XL. 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 dia- gram 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 maunfacturer’s guidelines carefully, as dbx is not responsible for dam- age relating to improper setup or implementation of the 234/234XL- 223/223XL.

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 234/234XL, or stereo 2-way or mono 3-way for the 223/223XL.

Use the literature that came with your speaker system to properly set up the mode of operation and crossover frequencies to the manufac- turer’s specifications.

There is one of the four possible mode button combinations for the 234/234XL which is marked “not valid”. Be sure you have not select- ed this combination as the 234/234XL will not operate correctly in this mode.
