Question about Music

1 Answer

I have a Kawai CN-2 digital piano that has worked fine for years. Recently, there is a constant white noise in both speakers that gets louder and softer when I turn the volume up and down. I've taken it apart and don't see any problems with wire connections, and can't find any mechanical thing that causes the noise to change for the better or worse. I've also tried different plugs, made sure there was no interference from other electronics, etc. Nothing seems to change the white noise situation. Does anyone know what might cause this type of white noise problem? Thanks, Tony

Sounds like a filtering cap is going bad. I'd suggest a repair shop.

Kawai mr-370 digital piano. Why is it stuck on the loudest volume and does not respond to the volume control slide?


The solder contacts on the fader may not be connected to the board. It may also be a software glitch. If you reboot / initalize the instrument it may fix it.

Some buzzing in left speaker when low notes played


A couple of possibilities
One the speaker broke loose, typically there is lock tight on the threads that hold the speaker in place, lower frequencies can also cause buzzing noise,
I have fixed this problem in the past with a hot glue gun, running a small bead carefully around the edges of the speaker, bonding it to the unit,
Another possibility is the speaker is blown or worn out, over time speakers can weaken from constant use and coil movement, in this case the speaker should be replaced...

Hope this helps?

What is the piano age by serial number 1872


Hello, you will need to look inside the Factory's site. Generally, they put a link to this purpose. If not possible, try a search section in Google, using words like: "serial number" age piano Kawai, changing the Kawai word for the name of the maker of your instrument.
Good luck!

It sounds like you are in need of a new piano. These are common issues with keyboards. The age is a big factor. It would cost just as much in repairs as it would to buy a new keyboard.

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.

Hi, I just got a new williams allegro digital piano, and the right speaker sounds noise with low keys.


If this is a brand new unit, exercise your warranty!

BUT FIRST see if packing material worked through the speaker grill... you know littel pieces of the packing peanuts or otherr contamination that sits in the speaker cone and rattles.

I have a Roland HP 101 digital piano however certain dont sound


White spirit is NOT what you should use. Mineral spirit leaves a residue film.

Use 99% isoprophyl alcohol.

ALSO inspect the contactboard for cracks by candeling with bright light behind it.
