Dbx 234X Professional Audio Stereo 2/3 Way, Mono 4-Way Crossover

dbx 234XL 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 power supplies 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
XLR balanced jacks that are bolted down to the chassis. This "nutting
down" 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 24 dB per octave
filters, the professional standard, but then again, what did you
expect?
