666 Posted October 5, 2006 Author Report Share Posted October 5, 2006 Is there no useable "headphone out"???unfortunately not in fact, there are no connections apart from that for the power supply....but it has a built in speaker, so it should be possible to amplify it externally?

Guest Neubeatz Posted October 6, 2006 Report Share Posted October 6, 2006 hmm, in theory if you can open it up, you should be able to attach a minijack socket to the speaker wires, you could possibly get a socket from somewhere like Maplin(cheap), soldering iron techy job, I think ??? mounting the socket maybe tricky,Come on tech minded peeps, help the bombardier!!!

David Posted October 7, 2006 Report Share Posted October 7, 2006 I created an output on a casio sk1 by wiring in a jack in place of the speaker, which seems to work fine running through the effects loop of a guitar ampI am not sure if this depends on the outputs and volume of the keyboard, the casio is only a battery powered job, so can't put out too much wattage into the speaker, somethign bigger might be worseDavid Quote Link to comment Share on other sites More sharing options...

666 Posted October 16, 2006 Author Report Share Posted October 16, 2006 thanks people.the advice is all well and sound, but no use for someone who isn't a circuitry wizard....does anyone know someone who does repair keyboards or something like that?x Quote Link to comment Share on other sites More sharing options...
