I have a Technics PR-305 Digital piano The back light is barely light when I turn on the piano Can that be replaced?


yes maybe you may fined that some of the power to the led is being blocked by causing a larger resistant to the led which will cause it not to light up as bright.

Crackling speaker as soon as i switch on my digital piano


It looks like the Korg c-15s has a internally mounted speaker and so I will assume that the speaker and amplifier are part of the piano base. It sounds like either the speaker is blown (crackling sounds heard as deformed voice coil scrapes the magnet structure) or the audio amplifier is distorting the audio.

Connect the piano's output to an external amplifier and speaker to properly identify problem.

I have just bought a PRX612M. When I play my digital piano through it at low volume there is a buzz which is most noticable as the notes volume dies down. Loud it sounds great but i would love to know what...


1000 Watts? Well, those are peak values. !000 watts RMS into a 12 inch speaker and it would smoke... this is some of our inflated advertising. But that is beside rhe point... now on to your problem: What you are having is a ground loop. You may have to do more than one thing to correct this here is the things to do in the order to do them to solve the problem:

1. Connect the piano and the speaker to the SAME power source or receptacle, even if you have to run an extension cord, three wire of course. Plug all of this ONLY into a grounded outlet, if your house has only two wire plugs, then you need to get an electrician to install a grounded receptacle.

2. Use Balanced lines. This means XLR or TRS balanced cables between the piano and the speaker. Use the 1/4 inch jacks output, not the RCA ones.

3. Since the AUX outputs do not support balanced lines, the next step require you use DI box. They are about $20 from Guitar Center and others. With very short 1/4 inch mono cable connect the piano to the DI box from the L/R mono piano to the high impedance input port of the DI and set the ground lift switch to "LIFT". Use an XLR to XLR cable from the DI box to the speaker. This last step if needed is the last thing in our bag of tricks to break the ground loop that can cause the buzz. Dirty power, if you have lamp dimmers can be a source of the noise.

I cannot get the grand piano sound......help somebody!


You are not clear if you can't select it or it just doesn't sound like a grand piano. If it is the latter here are the things to check:

1. Are your speakers at least 15 inch diameter with suitable tweeter as well? This is if you want the deep lows of the piano. Twelve inch are minimum size to sound anything like a grand. The internal speakers found in the pianos just don't quite make it as they are often only 4 to 6 inch.

2. Is your amplifier capable of enough power?

To get the REAL GOOD grand sound you need a capable audio system. A home stereo system just doesn't cut it to reproduce the sound of a grand piano.

I want conect speakers


DO NOT connect speakers to the internal speaker drivers as you may not match the amps You should use an external amplifier to drive speakers OR use "powered speakers" If you try tying into the internal amplifiers you are risking damage to the piano.

My akai ewi 4000s kind of froze


Please try to reset the ewi. You can do this like this: Shut down ewi. Press down the four little white buttons Level, FX, Setup and Trans. Keep them pressed while starting up the ewi.
This is a factory reset.

I hope this works for you.
