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.

When you are certain that the proper selections have been made, com-

plete the steps described below and in the “234/234XL-223/223XL Audio

Connections” section on page 7.
