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. This connecting 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?

- FUNCTION SWITCHES
Front Panel (Low Cut): Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one switch per channel
Phase Invert: Inverts the phase at the output, one switch per output
Rear Panel:
x1 / x10: Multiplies the low-mid (mono: low/low-mid) crossover frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel
Mode: Selects stereo 2-way, 3-way or mono 4-way operation and disables all LEDs for controls that are non-functional in the mono mode
LF sum: Selects normal (stereo) or mono-summed low frequency operation and disables Ch 2’s low output phase invert LED to indicate that this output is not operational in the LF sum mode
