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?

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 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 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 - to +6 dB, 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.
