First, plug it in. Next connect the speakers. Center all eq controls both master and channel. Turn off any reverb or effects. Turn the master volume 1/2 way up. Plug a sound source into channel 1 wiyj the channel volume all the way off. Turn on the amp. Slowly raise the channel volume until you heat output. If you get nothing, it's broken.
Are you using the 1/4 inch adapter- if so- make sure the mini plug is fully seated- you should feel 2 detents as you push the plug into the adapter- if you do not, you may be bridging the tip and ring colar with one channel and because it is not seated fully, it is not contacting the other channel at all.
Also make sure the plug for the headphones is fully seated into whatever device you are listening to. you should feel the 2 detents each time.
Yamaha FC4 and FC5 sustain pedals are normally closed, sorry Fred. Roland is opposite. I suspect the P120 just needs to be reinitialized. Hold down top white key (C) while turning on power. Wait 3 seconds and then release white key. Should now be reset to factory spec. Always plug the pedal in before you turn it on. If it still doesn't work check it with a meter.
The protect light generally comes on when the is a short in the speaker cabling. as a test, turn on the mixer without any speakers hooked up. If it still goes into protect mode the problem is in the mixer. Take it to your local music store and have their tech look at it. if it doesn't go into protect, check the speaker cables by plugging them in one at a time. The bad one will send it into protect.
Not uncommon for a switch to fail... especially the weak types they use on these strips. The inrush current when turning on the amps makes quick work of these switches. Replace the switch and get spares for the next time it fails.
Hi, blowing a fuse in an amplifier is a problem that most guitarists face at one time or another. If an amp won't turn on, or it turns on for a second, then makes a popping sound and turns off, the problem is usually a blown fuse. Though a blown fuse can be a hassle, especially during a performance, it does not have to put a stop to your musical enjoyment. With a spare fuse you can be back jamming to your favorite tunes in no time flat.
Things You'll Need
Turn off the amplifier and unplug it from the wall.
Locate the fuse, which is usually found at the back of the amp. The fuse will look like a small black wheel sticking out of the amp with a number and the letter V next to it. For example, 9V.
Gently turn the fuse counter-clockwise to remove it from the amp.
Discard the old fuse.
Insert the new fuse into the empty fuse slot and turn it clockwise until it is firmly in place.
Plug in the amplifier; make sure the power switch is in the off position.
Turn the amplifier on to make sure the new fuse is working properly.
I would try hitting the side of the amp before turning it on. There may be a loose piece of solder or other conductive particle stuck somewhere. Bang the cabinet rather hard with your fist. If that doesn't help it might be a loose solder connection at a resistor or capacitor but a tech should check that out.
