SOURCE: Yamaha P-200 electric piano does not have any

Plug in your ear phones to see if you can hear the sound that way. If not you are experiencing some internal failure in your integrated amp output.

In that case you will need to get authorised service.

Without power to the unit no sound should be generated. Make sure there are no other connections.

MAYBE you have a wall transformer behind it that is buzzing. MANY wall transformers develop buzz.

Another source is flourescent lights and even some of the low voltage halogens have noisy transformers in the base.

The master volume have a sond tha when it inn high become to noise and disturbing my ears

For decent signal to noise ratio your channel faders should be about 75% up. You should set the trims when punching down the PFL button for each channel so that peaks go up the meter to about 80% of max. Your master levels shoulld be from 50 to 80% up. You should be using BALANCED cables (TRS or XLR) everywhere. Your equipment should ALL be powered from a single receptacle or power conditioning module, even if it means running extension cords. Many people try to run unbalnced cables from this to their amps... it doesn't work and noise results. You didn't give us much info on your system so that we could analyze further

I am trying to run a monitor using the Aux Send on a Mackie Board but even with the Master Aux Send turned up there is barely any sound coming out when I try to use my microphones. Also, I noticed that...

No there is no special cord. The aux you use for a monitor should be pre fader( that means the signal comes before the volume slider) turn the individual slider all the way down. Talk into the mike at the volume you would be singing at the loudest. Adjust the gain of that chanel up untill the clip light comes on. Now back it down so it dosent come on at your loudest. Now pick the aux you want to use. Turn it up 1/2 way, turn up the master aux send coresponding to the channel aux number 1/2 way you should get sound. If it's too loud turn it down if you need more turn it up. If you have any more questions, give me a call at the shop.

On my yamaha v50 keyboard there is another sound on the keys after the c3 key how do i turn it off to just leave the synth sound?

5) Press the [+1/YES] button. 'OK' will appear beneath the 'Factory Set?' readout, indicating completion of the Factory Reset, and the V50 will automatically return to Play Mode.

NO power to my Casio CTK 671

First verify with a voltmeter that the adapter IS producing the voltage it is supposed to.

The cords and internals of these often fail.

Anything beyond that will require servicing. One could oppen the unit and look for bad solder or cracked board NEAR the power input jack.

My CASIO ELECTRONIC KEYBOARD CTK 4000 suddenly it stop working. When I press power button lcd window will light up briefly and turn back off. Please I need some help. Thanks

If you have a 12v power cord going to it i would try giving it a gentle wiggle. If you find a sweet spot and the keyboard stays on then you have a broken solder joint on the 12v input.

Not working

If it is brand new, it is likely "pilot error" as setting these up if you are unfamiliar with mixers can be frustrating.

There are several things that must be done to have a working system. Correct speaker cables are one and the setting of all the knobs are important...

DO NOT REPLACE FUSE. If any LED's are on, fuse is OK. If fuse blows, service the unit before replacing fuse to avoid further internal damage.

Make sure speaker cables are good.

Set the level control for the channel you are testing up AND you may need to press the "PAD" button to change the input gain. Turn up the master gain.

Depending on the source you are using, line or mic you may need to change the PAD button.

NOTE: This mixer does NOT have Phantom power and cannot be used with CONDENSER microphones requiring phantom power. You will get no audio from a condenser mic without phantom power. You must use dynamic mics with this mixer.
