Hi Kmuhren,

Welcome to Beoworld!  Beogram 3500 left the factory with a built in (non-switchable) pre-amp, which should give a line level output, although very slightly lower than other line sources typically (maybe around 90% of normal volume, which makes me think that your Beogram may be faulty if it is producing 20% of the volume you expected?)

It may be worth getting the Beogram checked out by a local audio repairer.  If you need any help with the female DIN to male 3.5mm cable to link the Beogram to theSonos Play:5, please drop me a line at steve@soundsheavenly.co.uk or click on my sponsor link at the foot of the page to get in touch and I will be happy to help!

Kind regards, Steve.

Hello

If you haven allready solved your problem, here's my thoughts about it:

I use B&O together with Sonos too and have had a Beogram 4500 LP hooked directly up to a Sonos Connect, and it worked fine. The 4500 also has a build-in RIAA.

In the Sonos app, under "room settings" (now it's called system settings, I think), there should be some settings you can fiddle with. There is with the Connect, so I bet it's the same with the line-in in the Play5. Maybe you have volume-limiter activated?

Also, I spoke to a Sonos supporter, and he told me, regarding volume-level of the line-in, that Level 4 (airplay) is the best one for all types of input.

I think you may have that set at a wrong level. Maybe, it's at level 1, which is lower.

My guess is you change it so level 4, and that solves your problem.

Regards.

Set the input to Fixed, Level 4 (airplay) in the sonos app, under system settings for your Play 5.

Regards
