특징
Stereo 2-Way or 3-Way. Mono 4-Way Crossover
크로스오버는 단순히 크로스오버 포인트를 나눠주는 기계일뿐이라고 생각할 수도 있지만 223XL과 234XL는 다른
제품들과는 달리 이러한 생각을 거부한다. 223XL과 234XL는 모두 차별화된 발란스형 XLR입력과 출력을 제공한
다. 공연도중 어떤설정에서의 돌발적인 변화를 막기위해서 223XL과 234XL의 콘트롤 부분중 몇가지는 뒷면 패널
에 위치에 있다. 223XL는 스테레오 2웨이 스테레오 3웨이 모노 4웨이의(선택된모드가 항상 두개의 녹색 앞쪽 패
널 LED를 통해서 표시된다.)4개의 모드를 가지고 있고 223XL은 스테레오 2웨이나 모노 3웨이의 2개의 모드를 가
지고 있다.
◈ 스테레오로 사용시:2웨이 또는 3웨이
◈ 모노로 사용시:4웨이
◈ 40Hz 이하 저음필터 스위치
◈ 각 주파수 밴드별로 위상전환 스위치 있어서 편리
◈ 저음 주파수를 모노사용 혹은 스테레오사용으로 전환하는 선택 스위치
Description
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!
