SUPER-X PRO CX2310

3.5 SUBWOOFER Output
To achieve a very loud and deep bass playback the SUPER-X PRO has an additional mono subwoofer output
for 2-way and 3-way operation. In this sense the CX2310 is a stereo 2-way + mono 1-way or mono 4-way
frequency crossover. The subwoofer signal is mono, since people cannot sense the location of lower frequencies.
Another reason is that combining all bass signals into a single signal produces an excellent effect. This is
because two bass speaker boxes combined together produce 3 dB more sound pressure than if they were
separated from each other by a small distance. The increased pressure is due to the speakers producing a
single wave front. With four loudspeaker boxes the increase is 6 dB. The reason here is the spherical shape of
the expanding low-frequency sound waves. Bass boxes which are separate from each other can mutually
disrupt each other where their sound waves meet (what happens here can be easily imagined if you throw two
stones into water—first separately and then stuck together).

As a standard, the BEHRINGER SUPER-X PRO CX2310 is equipped with electronically servo-balanced inputs
and outputs. The circuit design features automatic hum suppression for balanced signals and so ensures
trouble-free operation, even at the highest operating levels. Externally induced mains hum, etc. can therefore
be effectively suppressed. The automatic servo-function recognizes the presence of unbalanced connectors
and adjusts the nominal level internally to avoid level differences between the input and output signals
(6-dB correction).
