| Let's take a look at the construction features of the dbx® 234. 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 TRS
differentially balanced 1/4" 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. Owners Manual
