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. [. . . ] 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. Switch for reversing the polarity on the Low Output. An LED indicates the PHASE INVERT selection. 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. PHASE INVERT Switch for reversing the polarity on the High Output.

Switch for selecting the 40 Hz high pass filter. Selects crossover point between the LOW and HIGH outputs. Indicates that the LOW/HIGH crossover frequency range is 450 Hz to 9. 6 kHz. Controls the Low Frequency output level with a range of - to +6 dB. Switch for reversing the polarity on the Low Output. [. . . ] You may also use unbalanced cables to connect to and from the crossover. TROUBLESHOOTING NO SOUND If there appears to be no power: · Check that either the stereo or mono LED on the front panel of the 234/234XL-223/223XL 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. · Check that both the input and output gain controls are advanced sufficiently.
