Solos not Going into Standby (One Channel Only)

[rad1]

I've only just noticed this, having moved my Solos from a closed cabinet to an open shelf unit where I can now see them...

When my KDSM goes into standby, the left channel amplification does not go into standby but stays on full power. I have KDSM -> Solos x2 -> Solos x2 (piggy-backed for passive bi-amping) all connected with unbalanced cables. All settings are set for unbalanced. The left channel Solo lights stay bright, but the right channel Solo lights go dim when the KDSM is asleep.

When I first power up the Solos (switching on the mains switches) all four amps go into standby. But when they are woken up by the KDSM playing music, the left channel amps refuse to sleep again.

Have you tried swapping channels to see if the problem stays with that Solo?

I agree with ‘troll - swap channels and see if the problem moves. Seems unlikely two Solos would go wrong with the same fault at the same time. Is there a small amount of noise on the left that might be keeping the left Solos ‘awake’?

Make sure that power cables and unbalanced cable have a distance of at least 10 cm.

Hi Ben - that was it! Fixed. `All four on standby now.
Many thanks

So the power cables can induce enough signal into the signal cable to trip the Solo sensor. Wow.

It seems so. And it has impact on sound as well.

It‘s always good to have a distance between cables (Ethernet too) and also between cables of the same kind.

But I‘m only a listener, maybe others can explain better.
