No sound from 552 (shorted Snaic 5)

Oh no. Did you accidentally switch off the internal volume control ?

Glad to hear the rest of the system was ok.

@james_n thanks for tip. Does that setting mean you can prevent it going to 100 if you are a klutz? I cannot find that page on the app.

Hi IDAK - Yes. You can set the max allowed volume. 80% is the standard setting. You’ll need to access this via your Linn account rather than the app. This gives you access to the full configuration options.

Got it, thanks.

From the Naim DR Regulator White Paper.

Protection circuit
A protection circuit monitors the regulator and shuts
it down, via the zener voltage reference, if too much
current is drawn (in the unlikely event, for instance,
of a short circuit on the output) or if the regulator’s
temperature exceeds 70C. The protection circuit
is powered by its own ‘quiet’ power supply and is
designed to draw very low current, so minimising
the load on the unregulated supply that feeds the
regulator.

I assume the protection circuit did its job, as there was no collateral damage, just a single regulator to replace (on each occasion).

The protection circuit within the regulator is there to protect the regulator itself and keep the output transistor within it’s safe operating window.

All I know is the SNAIC shorted (within the cable, just below the DIN plug) and took out a single regulator. It’s been fixed and I’m using a different SNAIC cable and it all seems fine now.
