Hi folks:
I welcome advice from experts and non-experts alike
I have been asked to setup a semi-temporary sound system for a large outdoor swimming pool at a local YMCA.
During the fall and winter, the pool is covered with a 'dome' (think circus tent) that is roughly 200' x 100'.
It is out of the elements, but it can't be permanently installed.
Purpose:
PA during swim meets, Music during swim meets, Music during practices
'Audio quality' is not really a requirement
In past years, they have used:
- a 250w Radio Shack amp and 8x 4-olm un-powered speakers (wired in a mixture of serial and parallel)
There were complaints that it wasn't load enough and the amp got really hot.
They have basically no money to spend on something professional
They have a small mixer (that will allow a microphone and some audio device input) and several XLR outs.
I have come across 6x Anchor AN-120 powered speakers (for inputs, they have unbalanced RCA jacks and a balanced TRS/.25" port). They are crazy loud (and quality was acceptable) when I tested them connected to a PC (with a short 3.5mm-to-RCA cable). The speakers aren't 'active' so I don't think that I can daisy chain them together.
I would like to have a run of 3 speakers on each long wall (each spaced roughly 50 feet apart), with a cable OVER the pool connecting the two together. Imagine a big H, where the mixer is half-way up the 'right upright'.
I also have a couple Whirlwind Split 6 parallel line splitters.
I was thinking that I would have the following:
-- mixer-to-splitter (at the center of the 'right upright') -- 1 ft XLR-XLR cable
-- mixer-to-splitter (at the center of the 'left upright' -- on the other side of the pool) -- 125 ft XLR-XLR cable
-- splitter (center of 'left upright')-to-speaker (center of 'left upright') -- 1 ft XLR-TRS cable
-- splitter (center of 'left upright')-to-speaker (top of 'left upright') - 50 ft XLR-TRS cable
-- splitter (center of 'left upright')-to-speaker (bottom of 'left upright') - 50 ft XLR-TRS cable
-- splitter (center of 'right upright')-to-speaker (center of 'right upright') -- 1 ft XLR-TRS cable
-- splitter (center of 'right upright')-to-speaker (top of 'right upright') - 50 ft XLR-TRS cable
-- splitter (center of 'right upright')-to-speaker (bottom of 'right upright') - 50 ft XLR-TRS cable
Am I crazy (will I get line data to the far end of the cables)?
Are there any other recommendations about how to solve this?
Thank you so much!
Jeff
