DBX 223

All the inputs and outputs on the dbx 223XL are balanced XLRs that are screwed directly to the chassis.  This connection of the jacks to the chassis insures that even if someone stomps on a cable plugged into the unit, it's not going to tear up the circuit board inside.  All dbx crossovers feature Linkwitz-Riley 24dB per octave filters, the professional standard.

Via a switch on the back panel, you first select whether you're operating your system in stereo two-way or mono three-way.  Then you also set, on the back panel, whether or not you want to mono sum the LF (subwoofer) out.  Back panel switches allow you to select the range of the crossover frequencies individually for both channels. The crossover frequency controls have a green LED that indicates when the x10 switch on the back panel is activated. On the front panel you notice there are LEDs that indicate whether the unit is in mono or stereo mode.  Each channel has an input gain control for proper level setting. There?? a recessed 40 Hz low cut (HPF) on each channel to remove unwanted low frequencies.  Both the low and high outputs on each channel have a gain control ranging from -infinity to +6 dB to allow muting of individual outputs and for level matching.  Also, these outputs each have phase reverse switches that will help get you out of a bind without having to reconfigure your system. These phase reverse switches may be internally reconfigured as mute switches.
