Physical Installation
Logitek Audio Engine Reference Manual 9
For installations where an intense AM RF field is present, shielded CAT5 cable may also be used.
Coaxial 75-ohm cable may also be used for digital audio. Connection to devices, which do not have
coaxial connectors, will require use of an impedance matching balun at the device. Be sure to set
the impedance jumpers on the Digital I/O cards to 75-ohms if such cables are used.
Data Cable
Recommended cable for the Control Surface data is CAT5 cable. The maximum length cable for
Control Surface
connections is 1000 feet (300 meters). Shielded cable can also be used if there is a
risk of heavy interference to the signals, however this is normally not required.
 See Appendix C for pinouts of all cards.
Pre Assembled Cables
Logitek offers pre-made cable assemblies to M-66 block, Krone block, XLR connectors, BNC
connectors, or bare ends.
