How to implement an AUDIO IN socket for a WK-3800 ??

[daven34ar]

I have two keyboards one WK-3800 and WK-75000.
It is well known that the quality of the speakers of the 3800 is much better than those of 7500.
Is there any way ( hack or modification ) so you can hear the sounds of the WK-7500 , through the speakers of the WK-3800?
I ve have some basic electronic knowledge.
Thnx Daniel

If the WK-3800 has audio inputs you could always feed the line outs of the WK-7500 thru the Line input on the WK-3800 with the appropriate cable.

Seriously though, your best bet is to simply add a pair of powered monitors to the WK-7500 or even a Keyboard Amp.

I own a WK-6600 and managed to improve the sound greatly simply by patching it thru to a Behringer K450FX keyboard amp. It brings the bass response way up and makes the WK-6600 sound like less of a toy piano.

I just went to the Casio web page on the WK-3800. It does not appear to have any sort of audio input. Sorry. Without cracking the case and installing a mixer inside -- a non-trivial solution -- I can't think of anything you can do without purchasing something else.

It's interesting that the WK-7500 DOES have such an input. If you liked those speakers better, you could connect the outputs of the 3800 to the 7500.

How wedded are you to running off the grid? I noticed that both keyboards ran on batteries as well as AC power. When looking at an external amp (which will probably sound better than either keyboard's speakers), you should make sure that it has some sort of rudimentary mixer and that it runs off batteries. One possibility (which costs as much as a low end keyboard) would be the Mackie FreePlay, which takes eight D cells. (It also can be used plugged in, at which point it generates 300 W.)
