크로스오버는 단순히 크로스오버 포인트를 나눠주는 기계일뿐이라고 생각할 수도 있지만 223XL과 234XL는 다른제품들과는 달리 이러한 생각을 거부한다. 223XL과 234XL는 모두 차별화된 발란스형 XLR입력과 출력을 제공한다. 공연도중 어떤설정에서의 돌발적인 변화를 막기위해서,223XL과 234XL의 콘트롤 부분중 몇가지는 뒷면 패널에 위치에 있다. 223XL는 스테레오 2웨이, 스테레오 3웨이,모노 4웨이의(선택된모드가 항상 두개의 녹색 앞쪽 패널 LED를 통해서 표시된다.)4개의 모드를 가지고 있고,223XL은 스테레오 2웨이나 모노 3웨이의 2개의 모드를 가지고 있다.


Let’s take a look at the construction features of the dbx® 234XL. At first glance you’ll notice the units are great looking, and as you turn the controls something else becomes apparent; 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 we know how difficult external powersupplies can be to work with and even though it costs a little more we put the high quality power supply right in the unit. All the inputs and outputs are balanced XLR connectors that are screwed directly to the chassis. Thisconnecting of the jacks insures that even if someone steps 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 two switches on the back panel you first select whether you’re operating your system in stereo 2-way, 3-way or mono 4-way. Another back panel switch also selects whether or not you want to mono sum the LF (subwoofer) out. (Most systems that use a subwoofer are mono summed 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 the X10 switch on the back panel is activated (we 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 6dB, to allow muting of individual outputs and for level matching. Also, these outputs each have phase reverse switches that’ll 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 world’s finest processors for over 20 years. The technology that made us famous brings you a dbx® crossover which has been tested to the highest professional standards at a price that’s just too low to admit!
