Beocenter 9500 & Beolab 3 speakers

[RossJP]

Hi, following a previous issue with my Beocenter 9500 not liking my mix of 8 & 4 ohm speakers, I have bought a pair of Beolab 3 on eBay. I bought a pair of suitable length mk3 cables from AV Solutions Store on eBay too. However, I have plugged in to test and they don’t work. If you put them in the L or R switch position, the red light stays on and there is no sound (standby mode I assume). If you put them in Line mode, the lights go to green and very faint music comes out. This doesn’t get any louder with the volume being turned up on the Beocenter. This is the same on both speakers, even swapping cables and sockets on the Beocenter. Since I haven’t used active speakers on this amp before, it is hard to confirm if the speakers or BC is at fault. Or if I have bought the wrong cables. I think the mk2 cable are only required if you have speakers with displays, like Pentas. I also read something somewhere about different ages of speaker having different standyby wake-up voltage requirements… By the way, I have disconnected the passive speakers from the BC.

Could I ask, once again, for some help from you kind people please?

edit: I have just bought an adapter lead so I can test the speakers on the aux output of my phone or something, should be with me mid next week.

Do your passive speakers still work with the BeoCenter?

Are you sure that you haven’t removed/dislodged the little line in/out connector on the rear of the BC9500? (Just above the Powerlink 1 socket)

Otherwise yes wait and test the speakers with a phone adaptor.

Thanks Guy. I just checked with the passive speakers. L wasn’t working, but R was. So I looked into this more, and the balance was hard over Right. I know I need to replace the onboard battery because it keeps needing the reset code, and keeps messing with sound settings when disconnected. I have the battery and tools, just need the time. I also need to do the caps on the CD player, because I keep getting load errors, till it’s warmed up. Jesus, this thing is worse than my cars! (I drive & maintain 20ish year old BMWs).

I’ll get this phone adapter and go from there. I think I’m leaning toward this being an issue with the BC.

Would anyone be able to tell me what voltage I should be seeing on pins 1 & 4 out of the BC please?
