damages and the guarantee becomes void. Furthermore, any other operation may lead to dangers like short-
circuit, burns, electric shock, etc.
DESCRIPTION
The OMNITRONIC crossover is designed for professional application. The inputs and outputs are located on
the rear panel, the gain controls on the front panel.
The OMNITRONIC XO-2300 is equipped with ¼“ input and output jacks.
INSTALLATION
RACK MOUNTING
The crossover is built for 19" racks/483mm. The minimum mounting depth is 220 mm. The height is 44 mm
only. You can fix the crossover with four screws M6 in the rack.
When mounting the crossover into a rack, please make sure that there is a proper air circulation.
Please make sure that there is enough space around the device so that the heated air can be passed on.
The rack should be provided with a cooling fan.
Be careful when mounting the crossover into the rack. Put the heaviest devices into the lower part of the
rack. Be aware that fastening the crossover with four screws on the front panel is not enough. In order to
ensure safety, additional fastening by using ground and side bars is necessary.
If racks are to be transported or used for mobile use, additionally fasten the devices by connecting the rear
brackets with the side or ground bars of the rack. In this way, the crossover cannot be pushed backwards.
The front panel alone is not designed to absorb acceleration forces occuring during transportation.
INPUTS
A good cable run improves the sound quality remarkably. Input cables should be short and direct, since high
frequencies will be mostly be absorbed if the cables are unnecessarily long. Besides that a longer cable may
lead to humming and noise trouble. If long cable runs are unavoidable, you should use balanced cables.
The inputs of your OMNITRONIC XO-2300 are equipped with 1/4" jack socket balanced and unbalanced.
OUTPUTS
The high damping factor of your crossover supplies a clear sound reproduction. Unnecessarily long and thin
cables will influence the damping factor and thus the low frequencies in a negative way. In order to
safeguard good sound quality, the damping factor should lie around 50. The longer a cable has to be, the
thicker it should be.
The outputs of your OMNITRONIC XO-2300 are equipped with 1/4" jack socket balanced and unbalanced.

CONNECTION TO THE MAINS
Connect the OMNITRONIC XO-2300 only after having made sure that the right voltage (115/230 V) is
available. This device features a T 0,25 A, 250 V fuse.
STARTING UP
Make sure to power-up before your power amplifier is turned in order to avoid loud transients which could
damage your speakers or annoy your audience.
STARTERS' GUIDE TO CROSSOVERS
With an active crossover, you can separate the output signal of your mixer in different frequency ranges. In
this way you can define which signal portion will go to which amplifier.
The Omnitronic crossover can either be run in 2-way stereo or in 3-way mono mode.
Stereo operation is to be used in medium-sized and larger discotheques.
Mono-operation is to be used for larger PAs and requires 2 crossovers.
The crossover is delivered in 3-way mono mode. If you wish to run the crossover in 2-way stereo mode,
please press the stereo/mono switch.
OPERATION
2-way stereo operation
Please switch the stereo/mono switch to 2-way stereo.
The frequency is devided into two sections marked as channel 1 (left) and channel 2 (right). This user guide
will only explain the functions of one section.
Example for setting the frequency ranges (depending on the system and the room):
Bass Highs
100 Hz - 10 kHz 100 Hz - 10 kHz
The frequency can be adjusted via the Frequency-control, depending on the Range-switch between 100 Hz
and 1000 Hz or between 1 kHz or 10 kHz (LED lit).
With the Gain-control, you can boost the incoming signal level by up to 15 dB.
With the Low Level and High Level controls, you can attenuate the respective output level in order to avoid
amplifier distorsion.
In the stero mode, both channels should be adjusted the same way.

2-way stereo operation with mono-subwoofer
Most common setting in discotheque appliances. Phase erasions in the bass-range can be avoided and the
system gains around 3 dB in the bass-range.
Please switch the stereo/mono switch to 2-way stereo.
The frequency is devided into two sections marked as channel 1 (left) and channel 2 (right). This user guide
will only explain the functions of one section.

Example for setting the frequency ranges (depending on the system and the room):
Bass Highs
100 Hz - 10 kHz 100 Hz - 10 kHz
The frequency can be adjusted via the Frequency-control, depending on the Range-switch between 100 Hz
and 1000 Hz or between 1 kHz or 10 kHz (LED lit).
With the Gain-control, you can boost the incoming signal level by up to 15 dB.
With the Low Level and High Level controls, you can attenuate the respective output level in order to avoid
amplifier distorsion.
In the stero mode, both channels should be adjusted the same way.
3-way mono operation
Please switch the stereo/mono switch to 3-way mono.
Please adjust the desired seperation frequency between mids and highs via the Frequency-control mid/high.
Make sure that the range-switch is switched to 1:10. The frequency range ranges from 1 kHz to 10 kHz.
The portion of the mids can then be cut via the Mid Level-control.
The portion of the highs can then be cut via the High Level-control.
Example for setting the frequency ranges (depending on the system and the room):
Bass Mids Highs
20-550 Hz 550-6000 Hz 6000-18000 Hz
Please adjust the desired seperation frequency between lows and mids via the Frequency-control low/mid.
Make sure that the relation-switch is switched to 1:1. The frequency range ranges from 100 Hz to 1000 Hz.
The portion of the bass can then be cut via the Low Level-control.
