INSTALLATION
RACK MOUNTING
The processor is built for 19" racks/483 mm. The minimum mounting depth is 220 mm. The height is 44 mm.
You can fix the processor with four screws M6 in the rack.
When mounting the processor 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 processor into the rack. Put the heaviest devices into the lower part of the
rack. Be aware that fastening the processor 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 processor 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 SMP-152 are equipped with XLR and ¼“ jack-sockets and screw
connectors.
