dbx 223 Crossover
Let's 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". All the inputs and outputs are balanced XLRs that are screwed directly to the chassis. This connection of the jacks to the chassis ensures 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. 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. 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 indicating 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.
You'll get great performance, all the features you'd expect from a professional product and the knowledge that you're buying a processor from the people that have been producing the worlds finest processors for over 25 years. The technology that made dbx famous brings you a dbx crossover that has been tested to the highest professional standards at a price that's just too low to admit!
