The lightning flash with arrowpoint in an equilateral triangle means that there are dangerous voltages present within the unit. The exclamation point in an equilateral triangle indicates that it is necessary for the user to refer to the owner's manual. These symbols warn that there are no user serviceable parts inside the unit. [. . . ] LEDs are disabled for controls which are non-functional in mono 4-way mode.

LOW/LOW-MID X10 LED Indicates that the LOW/LOW-MID crossover frequency range is 450 Hz to 9. 6 kHz. LOW-MID/HIGH-MIDSelects the crossover point between LOW-MID and HIGH-MID frequencies. HIGH-MID/HIGH Selects the crossover point between HIGH-MID and HIGH frequencies. LOW OUTPUT Controls the LOW frequency output level with a range of - to +6 dB. Controls the LOW-MID frequency output level with a range of - to +6 dB. LOW-MID OUTPUT PHASE INVERT Switch for reversing the polarity on the Low-Mid Output. Controls the HIGH-MID frequency output level with a range of - to +6 dB. HIGH-MID OUTPUT PHASE INVERT Switch for reversing the polarity on the High-Mid Output. HIGH OUTPUT Controls the HIGH frequency output level with a range of - to +6 dB.

LED indicating mono mode operation. ® 6 223/223XL - 234/234XL 2-Way, 3-Way 4-Way Crossovers 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. There is a mode diagram on the back panel to help you understand at a glance how this is done. [. . . ] If the power cord must cross over audio lines, you should take care to have them cross at 90 degree angles. The input and output connectors are balanced/unbalanced 1/ 4" TRStype connectors. The tip of the plug is wired as hot (+), the ring is wired as cold (-), and the sleeve is wired as the ground or shield. The 234/234XL-223/223XL crossovers have differentially balanced input and output circuits. [. . . ]
