LIL'PA Portable public address system

HORRIBLE

This portable public address system is perfect for making announcements at our Music Collectors' Shows. It is not heavy to carry, easy to operate, and will work with batteries or a/c. (I bought this one to replace on that wore out with age!)

I just received and used the Pignose Lil PA (which is purchased from [...], for my private Tango and Hip Hop dance instruction. All I can say is: the Pignose lil pa cannot sustain clear sound for more than 2 minutes, the sound lowers down and lots of feedback. Also, the provided manufacturer microphone does not work or does not amplify.Before going to my dance classes, I thoroughly read the 2 page user guide then I purchased and changed the 9 C batteries provided by the Manufacturer from the original packaging to a 9 C Alkaline (this comes out to $12 taxes included), same results, sound lowers down and lots of feedback.Plugging the AC is a bit better but defeats the purpose of portability. However, same problem. Lots of feedback and audio lowers down after 5 minutes.For your information, I attached to the system an Ipod classic (fully charged) and attached to the 1/4th inch female input the PYRO lavalier wireless microphone transmitter.Attaching just the Ipod classic produces the lots of feedback and lowered sound problem after 2 to 5 minutes of use.The PYRO lavalier microphone (attached to the Pignose lil pa's 1/4 inch female input along with the ipod classic or just by itself scenarios) which attaches to the 1/4 inch input (I also bought new 9v battery and one AAA battery for the body pack)connector of the Pignose LIL PA only gives clear sound after talking for less than 1 minute. After that, no sound at all.The experience with the product is very frustrating on the get go. I am thinking of returning it to Pignose or to the seller [...] Pignose tech, any solutions?

I bought the Pignose lil PA for my church group and it had a similar problem to other posts, sound died out after a minute or 2. I am an electrical engineer and checked into the amplifier circuit. I discovered that the design is flawed leading to the bad performance. I fixed mine and it now plays great. The flaw is such that the internal circuit can actually self distruct. If yours still has some sound at initial switch on, then fails after a few minutes, it likely can be saved.
