DO NOT, repeat NOT, plug a mono plug into the stereo speaker jack on the
back of your K3.
The manual says that the microprocessor firmware will switch the audio
to SPKRS 1, which it will.
However, if there are other events queued up for the cpu to process, it
may take some milliseconds, during which time
the shorted output may blow the audio amp, which is chip U1 of the DSP
board. {What is the audio output doing on the DSP board instead of the I/O
board? - but that's
another story}
You then get to replace the DSP board - like I did - which is
good fun but a fair amount of effort. And it costs the company $.
