DBX 223 2-Way Stereo / 3-Way Mono Crossover
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 understands 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 TRS differentially balanced 1/4″ jacks that are bolted down to the chassis. This “nutting down” of the jacks ensures that even if someone stomps on a cable plugged into the unit, it’s not going to tear up the circuit board inside. Every dbx crossovers features 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 (so you won’t have to 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 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 20 years.
