grouping cables together in a bundle, all cables in that bundle should be intended for only
one signal type. Generally, cables should be grouped according to these categories:
1. Microphone
2. Line Level and communications (includes theatrical intercom)
3. Control and data
4. Speaker
5. Video
6. RF (includes wireless microphone and assisted listening antennae)
7. AC Power
Above all, keep the microphones cables separated from the others. They are the most
susceptible to interference since microphone signal level is so low.
If signal lines must cross, it is best if they do so at 90 degrees to minimize cross coupling.
The same grouping and separation also applies to cable tray paths and open cable routes (J-
hooks)
Cable bundling:
It shall be noted that where multiple cables of the same type, that conform to the groups above,
are to transit from a common source point to a common termination point, larger trunk conduits
should be used to carry these cables in bundles. Distribution boxes shall be added where the
Contractor feels that costs can be saved by doing so. This note also applies to the use of cable
trays and J-Hooks.
This approach shall be used wherever the Contractor sees the opportunity, and they shall provide
suitably sized junction boxes as part of their scope. Note: it is still the responsibility of the
Contractor to install the cable all the way from the source point to the termination point,
regardless of the conduit methodology used.
