I have been using a Sprout100 as the amplifier taking line input from an IEast renderer, connected to 6 ohm Harbeth P3ESR speakers and with LFE output to a sub. I have had it for about 6 weeks, but in the last two days it has periodically turned itself off without warning for no apparent reason. It loses the memory of the volume setting. Is there anything I should be looking at to find a reason for this? Since I live in the UK the unit was bought from your distributor here.
Does it turn off while playing? If so, is there a particular track or volume level that seems to trigger it?
Or is it turn itself off at any time?
I have only noticed it when playing. No particular track. Listening nearfield to chamber music so volume pretty low (60db). Sprout has always run slightly warm whether playing or not.
Thanks for the info - warm is normal so that’s no cause for concern.
What do you have Sprout100 plugged into? Directly into the wall? Or are you running a power strip?
It might be best to get your Sprout100 repaired or replaced. You can send me an email at firstname.lastname@example.org and I’ll get you in touch with the right people.
Plugged into a power strip. I left the amp on after finishing listening, and after about 3 hours it turned itself off.
Hmm, okay. If you don’t mind, send me an email at the address I listed above or email our service team directly at email@example.com.
The service team will be able to help us get to the bottom of this and get you back up and running.
Thanks, but I think I shall do a bit more investigation before calling the fire brigade. When it cut off today I switched it on again super fast and dialled up the volume in time to catch the renderer doing its irritating ‘The wifi is now online’ audio announcement, which means it had rebooted at the same time. This points to a power glitch, very possibly in the final brick on a congested circuit which was feeding both. I shall shift the Sprout to feed from a lightly loaded line and see what happens, or hopefully doesn’t happen…
My knocks off today and it seems that there are a few problems in the power plug. It just got a ride with a hammer. It’s PS audio, so it run again.
Since being plugged into a different outlet the Srout100 has behaved perfectly. The question by @Schroedster about where it was plugged in was a useful pointer. Previously it had been powered from the pass-through on the block providing USB power for the renderer, and I think this had an intermittent contact. Thanks for the help.
Glad to hear you’re up and running!
As always, I’m happy to help out if you have any questions or anything else gives you trouble.
