Ordered a pair for $50 to give them a shot…
Any advice on use / settings / etc?
Seems like the biggest concern is high SPL shows?
yes, high SPL is an issue w/ these, since there's no attenuation for gain.
other advice is, to turn monitor off, because there's a delay, which will give a constant echo throughout the show. Unless you can turn the volume up enough to drown out the PA, but, then, your visual will be off by a few milliseconds to the actual performance...
I gave up, because there are no local shows under the db limitations of the input gain, around here...
good luck! if they had simply put attenuation in-line to stop input overload, it would have been a nice system.
sometimes you can find them under $50, so, if you can find a deal, well worth the risk. There may be other applications to use these on too, so, even if they don't necessarily work out for concert & live performance, they might not be a total loss...
