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?

Just curious… What did you have before the BC9500? Were you happy with the sound level? Did you add the Redlines in order to get more volume or did you want rear speakers (or both)?

I had a Beomaster 5500, and I found it fine, but it was so long between last turning up that one loud and this one, I couldn’t make a reliable comparison. I do have a dB meter somewhere, if not, work will have one I can borrow…

I got the RLs for both, I like having 4 speakers because I like the way it spreads the sound round the room, instead of having such sweet-spots where the sound is better, it all ends up like a sweet-spot with 4 (to me, anyway). Extra volume is a bonus.#

I will probably try the Passive amp, since it’s quite cheap. While looking at alternatives, I wonder about Beolab 2s for the rear? I would then have a pair of column speakers up front, later, and maybe a Beolab 3 even later. One step at a time though!

I have just tried only the 5700 speakers, and on channel 2. It no longer drops volume at at full volume. Actually it might have a little with louder songs, but nowhere near as pronounced.

So maybe I’ll keep the 5700s up front and get some smaller Beolabs for the rear.

Thanks Guy, for your very helpful reply.  I had missed that in the manual, but think I was searching in the schematic rather than the block diagram for clues.  That would make sense then.

I had thought about the Passive (amp) units, but they are are only 3oW so probably not up to what I sometimes want.

The speakers are all in the same room.  I have the big 5700s up front on channel 1  and the smaller Redlines (45 I think) wall mounted at the rear on channel 2.  I can test if it’s related to the mute relay by only using the 5700s and putting them on channel 2, then see if the problem still happens.
