INSTALLATION

Rack mounting

The system-controller is built for 19" racks/483mm. The minimum mounting depth is housing depth plus 100
mm for plugs and cables. The height is 44 mm only. You can fix the system-controller with four screws M6 in
the rack.
When mounting the system-controller 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.

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 DXO-26/DXO-24 are equipped with electronically balanced XLR-
connectors.

Outputs

The outputs of your OMNITRONIC DXO-26/DXO-24 are equipped with electronically balanced XLR-
connectors.

Connection with the mains

Connect the device to the mains with the enclosed power supply cable.
The occupation of the connection-cables is as follows:
Cable Pin
Brown Live
Blue Neutral
Yellow/Green Earth
The earth has to be connected!
If the device will be directly connected with the local power supply network, a disconnection switch with a
minimum opening of 3 mm at every pole has to be included in the permanent electrical installation.

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 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.
