Mackie Tapco Th15a Thump Active Loudspeaker - Page 7 - Answered Questions & Fixed issues
Behringer GTX30 guitar amp. Channel switch setup: clean, but I can hear a little return of distortion, coming from the overdrive channel. This happens only on the speaker. Using the headphone everithi
If you are using headphones, then I'm guessing you are practicing and running the amp as quietly as possible while still able to hear it. Unfortunately, most channel switching guitar amps will have a tiny bit of bleed-through from the other channel when turned all the way down and listened to at close distance from the speaker. And yes, using a mechanical switch or relay to switch the connection from one channel to the other would mostly eliminate this, but due to the high amount of signal gain in guitar amp preamp sections, this type of switching causes very loud pops and other unwanted noise when switched. The amps are made with either photocell (optical) resistors or reverse biased transistors or op amp chips to switch channels. These are 'softer', partially because they don't fully turn off when in the off state(or fully on either). This creates bleed through, but it is better and easier than a CRACK THUMP POP!! every time you stomp the channel switch pedal. Amps are designed to be used at output levels generally much louder than a dorm room at 11:30 pm, and at stage volume in a club, the channel bleed is so far below audible, it is never heard by anyone. That's just the way it is.

Crate gfx 1000 digital guitar effects processor user manual
The problem I had was that i bought it secon hand and it didnt come with a wall wart for the power supply. This unit requires an AC adapter that is 9-10 volt ac output. Not dc output as most are. It will power up on a 9v dc adapter but it wont work. Has to be an ac adapter. Im using a 12v ac adapter off of something or other and it works now. Only need to hookup "in" and "out". Footswitch isnt necessary to operate. This thing is pretty awesome.

I have a viscount allegro digital piano and its power is not working when I try to turn it on. Can someone help me figure out why or how to fix it?
Hey!
It might sound a little obvious but... Did you try checking the power chord voltage? Those AC adapters are very susceptible to get damage and it might be the actual cause. You can try using a voltimeter (if you have one) and checking its actual value. Then, if it works properly, the damage might be on the power electronical stage on your digital piano and that might not be easy to fix.
This specific models are not 100% digital, so its power unit might have some analog components. Maybe there's something easy to fix and replace if possible, but if a new module is needed, I'm afraid it will not be easy to find.

Marshall MG50CFX. Why is there no sound output?
Unfortunatly, everything you told us says something is toasted. It would depend of what you thought of the amp when it was at 100%. if you put the money into fixing it. Personally, I'd replace it but hold onto it to use as an extention speaker.

Yamaha P-250 Stage Piano won't boot up...
Yamaha pianos go through a self test on start up. This could indicate a problem on the main motherboard.
Try a hard reset.
Hold down top C key while turning on.
Wait for it to start up, if it still freezes its time to take it to the repair shop.
