Oh, silly me!
Bought a used karaoke machine, $10, to use as a portable battery-powered amp.
Doesn't get very loud.
Right now, I'm running it off a battery adapter, plugged into the wall. Maybe the adapter doesn't put out enough OOMPerage to make it loud.
I'll get enough batteries -8 of them- C cells, tomorrow, and see if that makes a difference.
Discount battery store run by a charming widow, over next to the public boat launch.
She sell C cells, down by the seashore.
Anyway, if the batteries don't boost it loud enough, what might be a fix?
(I've already thought about throwing it away and buying something new, but, if possible, I prefer to FIX things, and keep them out of the landfills.)

The batteries aren't going to be more powerful than a wall plug. (8 C cells will cost more than the unit is worth). Double check all the settings, & look on both side panels for volume, tone, mute, filter etc settings. How much power is listed on the back of the amp ?. (You might consider just using the wall plug. I think you would get more consistent & reliable power over the time of a performance, & more consistent tone.
If you're going to stick w/ batteries, you might check out all the excellent reviewers on YouTube who compare most brands on the market. You might be surprised which battery gives the best value, & it is often not the budget names.

Looking for it on the internet, I found that you can buy from the company website for $79.99 and from J.C. Penney for $89.99. In that sense, you got a real bargain. Looking at the Singing Machine website it gives not power output ratings for the amplifier section. I finally found the information in the manual for the one you have. The audio output is 3.5 watts. In the world of guitar amps that would qualify as a practice amp as it is not very powerful. Those run from 1 watt to 6 watts so you little machine is right in the middle.
