excellent, let me know what you think.
Be sure to run the pre out's of your amp into the line level inputs of the
speakers.
They'll either have a separate line in jack, or a combo jack with a switch
to set either line in, or microphone in.
You may find the EQ and other filter settings are good, or you may find that
you can just use the eq on your sony preamp to adjust the tonality of the
source music.
Don't forget, the low cut, high cut, and eq on most powered PA cabinets are
designed for live audio applications. So the low cut usually chops
everything below 100HZ, and if there is a high cut, it'll chop everything
above about 6K...the eq will also be usable in a fairly narrow range with
pretty wide shelves...IE the bass control will adjust from 60HZ to 2K and
the high will adjust from 2K to 10K.
You might have gotten lucky and found a manufacturer that actually puts
shelving adjustments on the eq, or one that provides a 3 or 4 band eq
instead of a two band EQ like most of them do.
You got a good deal on those. Hopefully they meet your needs.
Have fun.
