Hello-

I have been in the Live Sound/lighting/productions business for a few years, but am looking to expand my business to include landscape sound installation. In the summer months, I work as a coach at the U.S. water-ski training facility. The owner has asked me to research and build a sound-system that will meet the following requirements:

I can simplify the explanation by saying this should be a sound system for a "summer camp"

The purpose of the sound system is to wake up the "campers" with a bugle reveille (form a central computer) and to announce when Lunch and other various activities are ready.

1. the system needs to be weather rated. The speakers will be outside in the heat and rain.
2. I will need in excess of 10 speakers, i think, to do the job adequately. I need to cover a main area of about 1 acer and a few smaller areas spread around the campus.
3. the dock's are over a thousand feet away from the main area. It will be necessary to have long underground runs of cable.
4. there are 10 dorm rooms along a common outdoor hallway they will need to be hit by sound.
5.i need to be able to adjust the volume of a certain "zone" fairly easily. I will install a few speakers inside, but i need them on their own volume control (preferably in-line).


My general idea is to have 6-10 speakers within 200' of the amp and 2-4 speakers 1000'-1500' away. There will also need to be 4+ speakers inside the main building.

I can split the system into a couple amps if necessary, but the only source of household power is inside the main building.


I no verry little about 70V systems, but im wiling to learn if someone can give me a brief overview. I know 70V is bad because it has bad freq. responce. I just dont know how to run the length of 1000 feet.

Thanks!
