I had the same problem about one years ago. I have two SP3 loudspeakers, on
on each receiver or both speakers, ore one receiver with the K3S audio
effects that use both loudspeakers.
The switch scratched when changing channel and it attenuated the audio
signals.

My SP3 A/B switch has an issue. I use the supplied speaker cable from my K3S
to the speaker A jack. I listen with the switch in the A position, but
frequently push it in to the B position as a convenient mute. Switching back
to A to listen, the sound is somewhat muted scratchy; cutting in and out
Hi,
Why would the amplifier be damaged from driving an open circuit?
Transformerless solid state audio amplifiers typically are perfectly happy
driving an open circuit.

Richard,
If your K3 has all the audio amplifier mods installed, there should be
no problem. If you have an early K3 without those mods, you could
damage the speaker audio amplifier by driving it into an open or shorted
load. Yes, the A/B switch will make the load to the K3 an open circuit
Doing so would mean outputting the K3 into an open load
I would at a minimum turn down the volume on the K3

Hi
I was wondering if there is a problem using the A/B switch on the SP3
as a on / off switch for audio from the k3. The k3 would be on.
It seems like this would be ok but I am checking with the experts here.
Thanks Richard
