Prime Go sound stutters (on battery, connected RCA to speakers with bad power)

hi guys, im trying some stuff out:

i want to use my SUV 12V outlet, to power small active speaker via 12V-to-220v inverter (from good brand) the speakers pulls 30watt at 40-50% volume i read on the inverter.

I connect the Prime Go with RCA audio, on battery for power

When i try to play music, the whole Prime Go stutters. When i play super soft, it does not stutter.

Any ideas why this happens? As far as i know the inverter has pure sine but im not sure.

Would a ground loop isolator work?

Im trying to find out how to play outside on the beach:

-im connecting Prime Go to bluetooth of car audio and open all the doors, this works but has terrible latency (even with sync its difficult). -im looking into power station -im lookin into generator -im looking into big speakers on batteries

-inverter is Voltcraft SLS 150-12 (150 watt) -speakers i connected are Presonis Eris 3.5

im JUST starting out with this project, would like to do some djing on a spot at the beach every week for fun (i live in Greece), no big crowd yet just a few friends

The part number seems to be for a clip/holder rather than the inverter.

You say it’s the Prime that stutters, yet the Prime is on battery, and the stuttering happens when the volume is increased, which leads me to think the “stuttering” is from the speakers i.e. the inverter is not suitable.

I found a Voltcraft manual (might be for a different model) which says that capacitors in power supplies and inductive loads are problematic. Also the 150W stated is likely not a constant rating but a peak one.

I’d suggest that rather than use mains powered speakers, wasting energy converting voltage up then down again, you’d have more luck running a sound system designed for 12V.

yes could be …but i actually SEE the Denon stutter, like the waveform itself on the device UI.

i think this is the manual: Technical Data - VOLTCRAFT SLS-150-12 Operating Instructions Manual [Page 39] | ManualsLib

its very wierd

i can also connect the inverter directly to the battery to try and see what happens…

in the mean time I ordered a ground loop isolator, to try

its an interesting project :slight_smile:
