223s, 223xs, 234s, 234xs Rear Panel Operations Section 3 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.
Section 3 Rear Panel Operations 223s, 223xs, 234s, 234xs On the back panel of the 234s/234xs, there are markings to help you connect the source devices and amplifiers to your crossover. To operate the 234s in stereo 3-way application, follow the top row of markings horizontally along the length of the 234s. For stereo 2-way operation of the 234s, use the second row of markings above the connectors. For mono 4-way operation of the 234s, use the markings directly below the connectors.
223s, 223xs, 234s, 234xs Electrical Connections Section 4 Section 4 - Electrical Connections Ensure that your 234s/234xs or 223s/223xs crossover conforms to the AC power specifications in your area, by checking the marked voltage spec on the rear of the unit. Never plug the incorrect voltage into your crossover, as this may cause severe damage not covered under the dbx warranty. Connect the power cord to the crossover first, then to a power source that is properly grounded.
Section 5 Features 223s, 223xs, 234s, 234xs Section 5 - Features x10 OPERATION If you are using your system in stereo 2-way or 3-way mode, the needed crossover frequency may be higher than 960 Hz, making it necessary to set the x10 switch to the active position. This changes the range of operation of the frequency selector from 45-960 Hz to 450 Hz to 9.6 kHz. All other frequency selectors remain the same.
223s, 223xs, 234s, 234xs Troubleshooting Section 6 Section 6 - Troubleshooting NO SOUND If there appears to be no power: • Check that either the stereo or mono LED on the front panel of the 234s/234xs or 223s/223xs is lit. • Check that the power cord is seated properly in the back panel of the crossover and that it is plugged into an active AC power source. If there appears to be power, but no audible signal: • Confirm that active audio lines are connected to the crossover’s inputs and outputs.
