I've noticed the hiss in the past, but prior use for these was as monitors in a rock/blues band. It wasn't an issue. I was trying to get an acoustic duo thing that went under and I've decided to try and strike out on my own. For the first time in a few months I fired up the PRX through my mixer and there is a huge hiss. It seems to mostly be driven by the acoustic guitar.
My experience with doing sound and operating this stuff is extremely limited. I have not done it in a band, although I've always tried to pay attention once the gear is setup. Usually most bands I've played with used powered mixers into non-powered speakers. While it might not be possible to eliminate the hiss, is there any way to tone it down? I don't really want to go out and buy another set of powered speakers at this point. When I strum chords it is not noticeable, but when I finger pick and or am not playing it is pretty bad.
Here is the gear in question....
Speakers: JBL PRX 512 (2)
Mixer: Carvin C1644P
Guitar: Guild acoustic with Fishman Presys Plus
Mic: SM 58
Types of music: typical acoustic rock, pop, blues type stuff like Wagon Wheel, Wonderwall, She Will Be Loved, etc, etc
The speakers are going into the balanced (XLR) of the mixer.
