(More customer reviews)I have owned this piece of equipment for a period of time. When I first used it with a 9V dc power supply, it had a terribly loud hum. So, I had to use a 9V battery instead to eliminate the hum. Then I decided I needed a 9V dc power supply to get a permanent power source to eliminate the chore and cost of replacing the battery. But, the hum!
First, I started to look for as "http://www.nady.com/mm141_mixer_pg.html" describes it "... or optional PAD-1 AC/DC external adapter." I just couldn't find the PAD-1 for sale anywhere online. I searched and I searched but to no avail. As an alternate solution, I bought a hum eliminator thinking that it will eliminate the hum but it was totally ineffective.
I did further research and found that previously I was using an unregulated power supply which was the source of the hum. My search resulted in finding someone that has a similar mixer with the hum problem and was able to rid the hum by using a regulated and filtered 9V power supply. I bought myself a similar power supply and viola! the hum is gone!!! I supposed I had found the PAD-1.
