Anybody else tested this?
I can't get speaker protection to work.
Or does it only work with higher AF levels?

* SPEAKER PROTECTION: If you’re set up for stereo speakers
(CONFIG:SPKRS = 2), but insert a mono speaker plug, the right
speaker output will be shorted to ground. This can cause excess
current drain if you turn volume up to high levels. The K3 now
detects this condition, automatically turning off the right
channel (and briefly flashing "SPRKS=1"). (It would be better,
of course, to use a stereo plug if you set SPKRS to 2, rather
than wait for the firmware to detect the mono plug.)
