I'm not sure if this is the forum to post this on, point me if its not - I did not see 'powered monitors 'in the speaker section.
I was given a pair of Event project studio 5 monitors. There's a possibility someone tried to use them as bookshelf speakers with an amp (uh oh).
They have nice clean output but low volume. Tested with a line input (ipod) on high vol, attenuator least attenuating and volume knob on high, they're room listening loud but not so any one would say turn it down.
Any guesses what the problem is, or how to troubleshoot? I looked for a shop manual/schematic with no luck. I'm guessing some input side component is fried. I'm electronics competent but no audio electronics expert.
thanks!

The manual says that 0.9 V input produces full power whith the input sensitivity control set at maximum. The manual does not say if the 0.9 V is RMS or peak to peak.
After a short search I doubt if an Ipod produces the needed 0.9 V. Could you try it using an other source, like a CD player?
It seems unlikely to me that someone tried these speakers as normal (so passive) speakers. How would they have hooked these up to their amplifier? It also seems unlikely to me that something is damaged, given that according to you the sound quality is still good.

you have a manual? (user or shop?) I found a user manual amongst numerous scammy manual sites. (Turns out Event was sold to the outfit that owns Rode).
So are you saying that if my young relative hooked the PS5s to an external speaker output of an older domestic stereo amp, ie presumably 8 ohm impedance, no damage would ensue?

It could have been damaged if abused. Are both speakers the same now?
Surely you can try connecting the Tape Out jacks from a receiver playing FM to see if you get more volume.

I would assume it is the source
I have have seen varying claims of ipod rms outputs from .3 to .6
So if the powered speakers need .9
then the source is a little short on the needed gain for full power.
seems if a component was damaged or malfunctioning
sound quality would not be good.
if they sound ok, more likely they lack enough gain for lower output sources.
been awhile since I used a ipod, but the one I had kinda sucked.
output was very low when I used it on various Aux inputs
was very low even on car stereo with aux, and that had lots of gain

user manual says .9v but doe not specify rms. I do not know how to measure rms anyway.
But, manual also says input 40Kohm balanced, 20Kohm unbalanced. My electronics knowledge is not sophisticated enough to know what might hav happened if they'd ben connected to a standard hifi amp 8ohm speaker out - but I'm assuming it might not be good.

RMS is the standard for AC measurements on test gear. Assume RMS unless you are told otherwise.
Connecting to another audio amp output could overload/damage the circuit. If you need to do this an L-pad attenuator would
usually be needed to protect and bring the levels down to suitable levels.
Phones/iPods have headphone outputs which are less than standard line-level output(*), powered speakers are designed for normal line-level usually unless specifically designed with phones/iPods/etc in mind. That's how it is.
(*) This is because battery life - they use high efficiency earbuds/headphones with these devices to extend battery life, which means that even 0.4V is deafeningly loud, and normal line-level voltages would cause hearing damage.
