distributed / wireless speakers
Daniel Levi:
I know Thomann have one of their own brand installation mixer amplifiers that will run on 24V DC so that could be a solution if getting power is a problem and generator noise is also an issue, https://www.thomann.de/gb/swissonic_sa_125.htm has 8Ω, 50V and 100V outputs, plus has balanced line inputs so could be connected to a good distance of balanced cable. Only 125W though.

i have got a question of a bgm project
during december . Yes you guessed right,
its christmas music. the thing is , that the possible client
wants the sound to be along a looooong walkway.
i guess around 1,5 km.
One solution could be a distributed speaker system
with amps in electrical cabinets along the way or
some kind of wireless meshing speakers.
Does any of you an idea of a wireless system like this ?
thanks in advance

apparently distributed should be the way to but it may involve road crossings
and some other obstacles along the (path)way. I was thinking in the ways
of placing speakers in lamp-posts along the pathway. But it's a bunch of cable
and about 25 - 30m in between lamp-posts :O
Another idea i was thinking of, was of a bunch of small radio receivers and small active speakers.
And let the customer hire a radio transmitter on a free and legal frequency :)
i was even wondering of the idea of wifi and decent acesspoints . . but than again,
active thing needs power . .
@mike caldwell - i dont know the budget yet. just throwing up ideas here to be a little ahead of the customer :)
we have a couple of those Yamaha PX10 amps that i maybe could use if i find a decent transformer :)
(we have bunch of LAB 4k's as well, but that would require some really bad-ass x-former :). )
@john roberts - stacked ? how ?

The big amps like yours will direct drive the 70 volt line, no out transformer needed.
An amp that will do at least 600 watts into 8 will make the 70 volt spec, you'll want to go a little
bigger for the line distance.
You can adjust the tap levels the further down line you get to balance the speaker levels.
Would this be just a one off thing or turn into an annual event, any chance they would want to have
year round music.

Unless you have a massive budget, this is almost impossible to do legally.

In the USA. OP is somewhere else in the world I’d guess since all his measurements are in metric.
