Krome 88:power cable problem:anyone relate to this fault?

Denv12 · Post by **Denv12** » Sun May 18, 2014 1:54 am

After looking at possible problems causding my new Krome 88 from being used to its full potential I think I've discovered a fault.The power cable is in 2 parts.
1)Plugs into the powerpint.Has a female 3 pin sockets.This plugs into
2)Korg Switching adapter.This is a cable with a rectangular black box.The 1st part plugs into this.

In the past I've experience similar faults with a Tascam DP03 digital recorde/mixer and 10 years ago a Yamaha MU100.Both needed the right cable to one end.The fault prevents the equipment working to 100% of its full capacity.
The DP03 couldnt be used until I got the right part and the MU100 kept cutting out.I'm asuming there are Korg owners who might have similar problems with their Krome and even Kross.

Here's my main post regarding problems with this piano.

So far nobody has reported any issues with their Krome or Kross because of this. I don't like wall warts either, but technically there is no difference between an internal and an external power supply. The fact that you have had issues with previous products that happened to have an external one says very little, if perhaps that the power at your house is less than optimal. Using a UPS with voltage regulation might help.

I dont have power problems at home.I have a problem with my piano not working to its fill potential.I'm using what the piano came with.I'm assuming its not the correct one.

What does "not working to its full potential" mean? You haven't really described what's wrong yet. It's still entirely possible the adapter is not working right, I agree. Seems unlikely you would have gotten the wrong one, but it's easy to check as they generally list the specs or at least a type number on it.

Here's my post in regards to my problem.

On one part these are the details:

LEE YUEN.
The other part reads:

All I'm getting from that post is that your piano and ep don't sound as good as the ones in the video. Since the Krome apparently boots up and plays fine it seem unlikely to be a problem with the power supply.
Can you be more specific what the problem is?

The overall sound of the entire piano isnt right.Something is wrong.I cant describe it any further than what I've already described.

"Piano" is usually used to refer to the piano sound. Is that what you mean, or do you mean all the sounds from your Krome. Off the top of my head, is it possible that you have a panning issue? Are you sure that you have panned input one on your recorder all the way to the left, and input two all the way to the right? My Kronos piano sounds terrible in mono, definitely make sure the entire signal path is stereo and not dual mono. I'm guessing you've also made sure the input gains on the recorder are set properly? Would it be possible for you to make a recording and post it? It would help trying to solve the issue.

Nevertheless, if you are convinced something is wrong with the Krome, I would not wait any longer and take it in for a warranty repair.

I refer to piano as every sound on it overall.

What I dont understand is that my Roland RD700SX stage piano was connected up exactly the same way and never had any problems.When I unplugged the 2 cables from L-R of the Roland ,unplugged the power then packed the Roland into its box then put the Krome on the piano stand in its place and connected it up.It doesnt sound the way it should.

I've sent email to Korg in Australia.I'm going to ring them at 9am.
I'll record a demo and post it here.
