I purchased Gear One powered mixer for PA system in November. Last Friday evening we had some problems with seemingly drop in volume several times. I set it up in my garage and it works fine but I feel that it does not have the volume that it did when new. It is a budget priced solid state mixer. My question is can a solid state amp loose volume and still sound clear meaning good in every way but just not as loud? All the channels sound the same and I can work the master volume control up and down and don't find a weak spot. Does this have to be just my imagination? I will have a better idea about it after next Friday evening but am curious as to whether solid state equipment can act this way. I hate to send it in for warranty work and find that nothing is found to be wrong with it.
Thanks,
Jerry

Jerry, I have had stuff like that happen, and it turn out to be loose connections inside the board. I used to have to slam the back of a Carvin amp with a hymnbook (sorry God) because the power amp chip's connector would be loose. I finally went in to it and got rid of the connector and used some good old solder on it.

I may, in fact, be nuts. However, I am screwed onto the right bolt... Jesus! |

If you connect too many speakers then it will heat up and shut down... Pay attention to the manual!

Have you checked the input AC voltage supply while in operation? If this is a Class D power amp, they are much more picky on input power requirements than older designs.
Like most things, there are good designs and not so good designs.....

Yes, it's rare, but that can happen to any amp - solid state or tube.  |

The title of your post is confusing. Are you having trouble with a powered mixer or powered speakers or both. If you are sending signal to powered speakers from your mixer's line outs be certain to check the volume knobs on the speakers themselves.
Also if you are sending line level signal to powered speakers a bad cable between mixer and speakers would present just such symptoms as you describe.
Likewise a shorted 1/4" connector (which happens all the time) on the unshielded cable between a powered mixer and passive speakers would cause the volume to drop but not necessarily fail altogether.
Finally, maybe you are using a shileded guitar cord rather than the appropriate unshielded cable between the powered mixer and passive speakers, this would cause a number of issues, including those you describe. |

What Dave asked 
I'm sure both your speaker cabs are rated at 8ohms, unless you're running something like two 15's in each cab, which might be a 4ohm load. So I doubt if it's a heat problem due to a load situation. Most powered mixers are designed to push 4 or 8 ohm loads. If memory serves me right, isn't "Gear One" a Musician Friend product? Anyway, ya might check all masters, and make sure when you use your mixer, that you don't continually Red Line a channel. That might also cause major play problems. Sound guys call it "Channel Fatigue". Did the mixer feel hot? smell hot? operate other wise normally?
And Dave gives sound advice. NEVER use a guitar cable for speaker cables. Especially through a powered mixed. And as a side note, speaker cable is cheaper then audio cable by the foot.  |

It is a powered mixer with passive speakers. I am using new #12 speaker cables. No smell, no heat. I talked with Musicians Friend and they advised me to send it back to them and they would send a new one so maybe my problem is solved. Thanks for all the responses. Dave, you are right, I did not mean to say powered speaker. It is a powered mixer. OK to close.
