Starting Up; Starter's Guide To Crossovers; Operation - Omnitronic XO-23 Mode D'emploi

The device must only be connected with an electric installation carried out in compliance with the IEC
standards. The electric installation must be equipped with a Residual Current Device (RCD) with a maximum
fault current of 30 mA.

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.
System test
After connecting all cables, you should carry out a system test. Press all four Mute buttons in order to mute
all outputs.
Activate the HF outputs first. In case of wrong cabling, HF signals will come out of bass speakers that cannot
be harmed this way. Vice versa, the LF signals would destroy your HF speakers.

Starter's 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 2-way stereo mode. If you wish to run the crossover in 3-way mono mode,
please press the stereo/mono switch.

OPERATION

Front panel
Channel A and B are identical.
1. POWER Switch

avoid loud transients which could damage your speakers or annoy your audience.
2. INPUT LEVEL Control
To adjust the input level from - to +6 dB.
3. LOW CUT Selector
This switch activates the highpass filter and allows you to cut down unwanted low frequencies.
With the Low Cut function, you can attenuate all signals below 30 Hz. Please keep this button pressed if you
do not need these extremely low frequencies at any rate. If your speaker-system does not support these
frequencies, there is danger of speaker damage!
4. PHASE Control
This control reverses the polarity of the Low output.
5. LOW OUTPUT LEVEL Control
