Headphones Output
      #1059494 - 27/07/13 04:17 PM
Hi everybody,
I have an electric piano, which it's output is Headphones (standard stereo jack).
It comes out that when I plug the piano to speakers / mixer, the sound that produced is not so qualitative.
My question - is there a way to overcome this problem and make a better produced sound quality - by any solution (Apart from buying another piano...)
I have no problem also to buy an adapter if it's needed for this output or else.
Just for general knowledge - these are the ports that my piano has:

* Headphones (standard stereo jack) - as the above would look like
* Sustain / assignable
* Audio in
* Mic in
* USB: type B
* External power (12V DC)
* USB cable (AB type) required to use USB terminal for computer connection.

Thank you!

Hi, Are you sure your "audio in" is not an audio out? Why are there no dedicated outputs? I would double check your audio in!! Otherwise, realistically, try and change your keyboard for one with dedicated outputs NOT headphone outputs. Dave

Strange that there is no TRS jack out or XLR outputs.
You could use the USB port to connect to an external USB interface.

Have you tried a combination like these:

with mic inputs on the mixer?

My goto solution for this, is plugging a 1/4"TRS to dual 1/4"TS cable (An insert cable if you are familiar with this term) into the headphone jack, and then running the dual TS jacks into a stereo DI box, where I run to the mixer from the DI box. I also run out of the thru-outs of the DI box to an amp for a monitor, generally along with a feed from the mixer, but no idea what your setup there is like. If you are running off a powered speaker I would generally depend on the mixer to feed you a mix then as many don't have a built in mixer like a keyboard amp can.

You could use the USB port to connect to an external USB interface.




It is not uncommon, particularly in small portable digital pianos with onboard amps. (Yamaha P90/P95 is one I commonly see like this on stage)

And no, you almost certainly cannot use the USB port to directly connect an audio interface. It is almost guaranteed that the USB port on the keyboard is a client port, not a host port, and the keyboard OS has next to no chance of knowing what to do with a USB audio interface.

Just a note that a guaranteed way to get a very thin and tinny sound is to run a TRS cable from a headphone jack to a balanced input on the mixer.... (You only get the difference between L & R which generally equates to no bass and a very thin sound)

The cure of that one is a 'insert' lead to a stereo input.

Regards, Dan.

Audiophiles use phono leads because they are unbalanced people!

Are you taking this stereo output into two separate mono inputs - either on a mixer 'stereo input' channel or adjacent line-inputs - or to one mono input.

If it's the latter then you could have fallen foul of the problems associated with merging left and right outputs to one input by using a simple adapter. The rule with output adapters is 1:2 = good; 2:1 = bad.

So if this is what you've done you need something like THIS . (Other makes are available!)

If I have to do this I run the keyboard output as hot as possible but not to the point of introducing distortion and ensuring your connecting to a proper line-level input.

Indeed, make and model please.
OP: If you are saying that the headphone out sounds nasty when feeding an external amplifier it might be that the source needs a load. I would make up a TRS jack with 100 Ohms from left and right to common then take off a feed to each amp channel.

Dave.
