JBL 4305P Roon

I am loving my 4305P. I am using my Nucleus as multi room. Down stairs it powers my Cambridge Audio CXN V2 and upstairs my new 4305Ps. I used my MacBook Pro, iPhone and iPad, and across all of these something strange is occurring. Initially I got lossless and then enhanced with Muse showing up as unknown. When I reset the speakers I am back to lossless, which sounds much better, but when I turn the speakers off and back on it’s enhanced again. Help. I just want lossless with no dsp.

Thanks.

Please post screenshots of the Roon signal path, ideally of both versions

The file is low res too.

Will rest speakers when working in office. It shows lossless with nothing showing for Muse.

Looks like the DSP is happening inside the speakers. That’s not something you can control with Roon. I’m not sure why it says “MUSE”, but perhaps when JBL implemented Roon’s firmware as part of Roon Ready certification, they forgot to change the name of the internal DSP?

Yes Jamie Madden at Roon said the same. Shame, as they are louder and sound better without the processing. I guess I just have to reset every time I turn them on.

This is what happens when I either reset the speaker using the button on the back or power off.
When the speakers go into standby they return with Roon as Enhanced.

JBL and Roon are “Brothers under Harman” maybe ?

Good conspiracy stuff eh ?

Think also, that JBL must resolve this issue, but can you disable (temporarily) auto standby for the JBLs?

I don’t think so. But the processing definitely resets after standby.

Well if it passed Roon Ready in this condition then it is by design and in accordance with whatever conditions Roon deems necessary to pass certification. It is a shame that Roon Ready means different things depending upon implementation, with the user left in the dark until they have purchased the item and find out the implementation details for themselves. Every manufacturer could list the implementation details of course but I have never seen a single one do that.

Slightly OT but I had to disable auto-standby on a pair of active JBL monitors because it simply didn’t work and just turned them off after 20 minutes precisely even when audio was playing. I had to look online for the PDF manual as to how this was done. It was an EU power saving directive apparently.
