Using the same wireless system in three rooms
« on: November 19, 2008, 02:27:41 pm »

Hey Everyone,

I've got a possible install coming up that requires the same wireless system (most likely Shure ULX) to be used in three different rooms.  Two of the rooms are adjacent and the third is just a small hallway away.  I would like each room to have full diversity.

This is really to save money, instead of each room getting its own rack of wireless, there will be one rack of wireless to serve the entire facility, Probably a total of 6 receivers that could be used in any combination amongst the different rooms.  

I flat out don't understand enough about RF to pull this off.  I would appreciate any ideas or examples!

Thanks,

Chris Parsons

How are the rooms wired for sound now?  More information, please.

Hello Chris,

   This can be very complicated to the unexperienced.... you should hire someone from this site as a consultant... a few hours of work and they could get you headed in the right direction.

Cheers,

I will be using Symnet for audio routing/processing.  I've got all of that worked out actually.  All I need is a little help with this RF problem.  Have any of you encountered any similar situations?

Thanks!

Chris-

The simple solution here is to just have a single rack of wireless or several single or dual receiver wireless packs that can be toted from one room to another. Then the output(s) can be plugged into regular wired jacks in each room.

This also affords you the flexibility of putting regular wired microphones in the rooms as well.

This will be a LOT less expensive than installing a bunch of antennas throughout your facility and combining them into a single wireless receiver or four.

I have done several divide/combine type applications with three or more rooms and a central rack with the wireless receivers.  The RF part is usually pretty easy to address if the rooms are adjacent, but figuring out what transmitter and corresponding receiver is being used in which space and how to tell the system that can be more complex.

Would you mind elaborating on this?

In the combinable room projects I've had it was possible to locate the antennas out over the ceilings such that the antennas, or at least one of them, could still pick up a transmitter in any of the rooms.  For example, with three divide/combine rooms we might locate an antenna above the ceiling near each of the two room divisions.  As you move from room to room or around the spaces it may switch which of the two antennas is in use but you can usually move throughout the space with pretty good coverage.  It may not be the ideal, but so far it has worked without any problems.

Also, if I have more than a couple of receivers, I usually use an antenna distribution system.
