Just take a look at the construction features of the dbx® 223XL. As you turn the controls you will notice that these units are extremely well built. The controls exude great precision, and the feel is a solid “click.” Also, when you open the box, you won’t find the external power supply that accompanies most processors in this price range. That’s because dbx knows how difficult external power supplies can be to work with and even though it costs a little more they put the high quality power supply right in the unit. All the inputs and outputs 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 all feature Linkwitz-Riley 24dB per octave filters, the professional standard. But then again, what did you expect?

Via a switch on the back panel, you first select whether you’re operating your system in stereo 2-way or mono 3-way. Then you also set, on the back panel, whether or not you want to mono sum the LF (subwoofer) out. (Most systems that use a subwoofer are mono subbed to take advantage of amplifier power and because low frequencies are non-directional.) 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 (they wouldn’t make you check the switch position on the back every time you wonder where it’s set). All these switches are on the back panel because it could be disastrous if you were to change them mid-program. On the front panel you’ll 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’s 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.

Function Switches
Low Cut Activates the 40 Hz Butterworth 12dB/octave high-pass filter, one switch per channel
Phase Invert Inverts the phase at the output, one switch per output.
x1 / x10 Multiplies the low-high(mono: low/mid and high/mid) crossover frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel.
Mode Selects stereo 2-way or mono 3-way operation and disables all LEDs for controls that are non-functional in the selected mode.
LF Sum Selects normal (stereo) or mono-summed low frequency operation and disables Ch 2’s low output phase invert LED to indicate that this output is not operational in the LF sum mode.
