OMNIA MPX NODE MANUAL
14 Technical Notes
Firewall and Security
MPX Node has basic internal firewall functionality which is designed to protect the unit
from certain types of network probes and intrusions. It is not meant to replace a properly
implemented external firewall or security plan, and it cannot protect any devices other
than itself. The firewall blocks certain ports coming into the device to keep system ser-
vices from becoming potential attack vectors into your LAN. For best results, a properly
configured external firewall is recommended.
Tilt Correction
MPX Node is flat and expects to receive a signal that does not require tilt correction.
If either end of your chain requires tilt correction this must be accomplished external to
the MPX node. To test if Tilt correction is necessary, feed a square wave through the audio
processor into the MPX node, and verify you see square wave on the meters of the MPX
Node.
Cooling
MPX Node’s thermal design transports heat through the chassis, to exchange with the
outside air. For best results, do not block air vent holes on the top or sides of the unit, and
maintain ambient air temperatures below 40C in your rack. As with all electronic equipment,
heat ages chips and circuits faster, and cooler environments will prolong equipment life.
