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,234XL은 스테레오 2웨이나 모노 3웨이의 2개의 모드를 가지고 있다.
