I have a situation that needs professional help!

Here's what I have and want to do. Several times a year, our local high school baseball stadium is used for other venues, with a stage area setup out in center field, a distance of about 200' back to the press-box where the stadium's PA system is installed. In previous venues, we had two choices; 1) announce from the press-box, 2) place a system (with a generator) out near the stage and announce from there. Also during these other venues, we've used a 2nd amp and speaker--a BOSE system on the press-box roof and have sent sound and music to an adjoining field and the parking areas which works well.

Here's what I want to do: Link a small system out in center field with the system in the press-box. I have tried a Nyrius 5.8 ghz wireless audio/video sender-receiver model NY-GS3200. This seems to work--it is "line of sight" but sometimes there's "gaps" in the signal and the receiving system(s) will emit rushing noise as if the squelch was turned off. So, this brings a couple more questions:

1) is there a better solution--but not as expensive as a kings ransom--that will accomplish this? Has anyone tried using a low power FM broadcast transmitter and an FM receiver at the receiving end with any success? I would guess that selection of the right frequency would be important--and anything that would work in the daytime might not work after dark and many stations crank up their power and could cause adjacent channel distortion.
2) Is there some additional setup I should consider--should the transmitting station be raised up? I don't think that it's so low that the signal is being blocked by anything, but I'm just wondering.
3) Is there a WIRED solution I could consider? I could string a wire, using temporary posts pounded into the ground so that it wouldn't get stepped on or tripped over. But in this situation, what would you suggest? A shielded XLR cable--I would suspect it would need to be custom made for this length? And if I did this would there be enough signal to feed the line-in(s) of my secondary amps? I know that the 70v line for speakers has nearly an unlimited length--but how would I go about making the appropriate connections and conversions?

I know I've probably asked more than my share of questions here--but I can't be the only person that has this need--so your professional guidance is much appreciated!

thnx, ja

1) there's always better.. but given that I've never heard of the brand of wireless you're talking about, definitely you could go much better without breaking the bank.
2) yes, raising the transmitter and receiver up is a good first step for any wireless transmission that is borderline or mission critical setups that need an extra safety margin.
3) wired is always the cheapest and most reliable way, but if you can't run any cables on the ground that may be an issue.
it may seem really far to go around the crowd, but I'd personally rather go 500'+ wired if feasible than attempt wireless on a budget. no need for custom. if you don't have what you need you can rent more XLR from your local rental shop for next to nothing.

BUT the biggest consideration that you probably haven't thought about is that there will be a significant delay between the sound wave leaving the stage and getting to the stands, so you'll have to delay your pressbox system so that it lines up with the arrival of that sound wave and not the original output (ie: sound on wires or airwaves are way faster than a sound wave through air)
you can rent a delay when you get the cables...

Not to be a jerk, but would you go to the forums for "professional help" on medical issues? Perhaps you should look at consulting a local professional.

David, the guy is not asking how to perform brain surgery. Some folks have the time and aptitude to learn and execute solutions to problems that are not within their normal field. I say give him the info and let him have a whirl at it. Maybe he'll learn something new and have some fun while he's at it. If he fucks up, nobody dies. If it's important enough to get right, he'll figure that out and hire in someone who knows what they are doing if he has the budget.

may want to check this out...
AS-WSS11T
saw at infocomm and may be a reasonable solution...looked at the wireless system you indicated from Nyrlus...i would not use that at all....i would be very leery of it beyond 25' or so...
maybe post a diagram of what you are wanting to do with the amps, speakers, etc. would help
 
Re: I have a situation that needs professional help!

If it is several times a year maybe you should consider having a permanent run installed. Allow you to just plug and play in the future.
Just what I was going to say. Have an electrician drop in a pair of conduits (one for audio and the other for power) to the stage area. That way you can power a system at the stage and delay a hard wired line to grand stand system. Run multiple balanced audio lines from the stage so that you can run several mics, if needed. Pretty much all bases (no pun intended) covered. This is definitely hired high volt electrician work as it will require permits and inspections.

"Professional" meaning someone with more experience than I! I've found out a lot of forums without even posting, and I did search many of these looking for similar situations--none found. Now I have some good starting points! Thanks to all for the assistance.
 
Re: I have a situation that needs professional help!

I'm not clear on the overall situation and am having some difficulty seeing how the installed baseball field sound system would be used for events with a stage in center field. What are these special events and what do they involve? Is it just one or two microphones out on the field or bands or what? How do you plan on handling mixing, level control, etc. for the special events? What is the installed system and what areas does it cover? When you have these special events are all the audience in the coverage of the installed system or are you looking at the installed system being just part of a larger system that has additional temporary components?

Is there a reason you can just run a few longer cable runs, they don't have to be exact length, using cable covers or protectors/ramps? You might even be able to rent these as needed.
 
Re: I have a situation that needs professional help!

I've been using ordinary IEM transmitters/receivers for distances up to 600' .
 
Re: I have a situation that needs professional help!

Sorry for the thread hijack, but how are those of you using IEMs for remotely driving a speaker connecting them to powered speakers (or remote power amp)?

While I've not done it personally, I expect that they are just using the headphone output of the IEM beltpack and plugging it into the amp rack, or into a preamp that then drives the amp rack.

This can be done in much the same way that you take the headphone output of your iPod or cell phone and plug it into the system for testing or walk in music.

If I'm driving two speakers, I normally use a Stereo 3.5 mm to dual momo 6.3 mm lead into a stereo DI-box, running XLR to the active speakers. If only using a single active speaker, i plug one of the mono 6.3mm jacks into a jack to xlr adapter, shorting xlr- to ground with tip going to xlr+. It isn't balanced, but that doesn't matter at all.

Perhaps you meant "expert" rather than "professional" (which means someone who does it for money). Not all experts are professionals - and not all professionals are experts!!!
