I want to use an MX5500 with a BM4500 and a pair of P45s in a bedroom.

The TV and BM will be connected via the their respective AUX sockets and the P45s connected to the BM4500.

If I set the BM4500 to option 2 (displays 2.5) and the MX5500 to option 0  with its speakers set to External then sound comes from the P45s connected to the BM4500 as expected but when I switch to TV I get the sound of the TV from the P45s but no picture.

If I set the BM4500 to option 0 (displays 0.5) and the MX5500 to option 2 then I must set its speakers to Internal to get any sound.  When I press TV the BM does not come on.  When I press radio then sound comes from then MX5500 and the BM4500 always mutes.

What are the proper option settings?

Is there a definative guide to the options?  There are bits and pieces in a few user guides but an overall guide would be nice...

Doesn't the MX5500 have connections to allow the P45's to be directly connected to the TV?

Yes it does but I thought the amplifier in the BM4500 is more powerful.

So I use A.OPT 0, V.OPT 2 and connect the speakers to the MX5500?

Yes, I believe the only "good" setup is having the speakers connected to the TV. The downer is that the amps in the MX aren't that great, and I wouldn't trust the quality of the audio routing circuitry that much either (so even active speakers wouldn't solve the whole problem)...

I once tried to setup my BS6500 (with passive Pentas) and MX6000 so that the TV sound would come automatically through the BS while audio functions would continue working normally. I never got it completely working - either the picture was missing or the TV turned needlessly on.

I'm not sure, but I remember there has been a SW issue for early MX5500/BM4500
and similar setups beeing not capable for a "full" A/V Opt.Setup 0/2
(the two digit readout e.g 0.5 or 2.5 indicates that it might be the old SW version)

SW versions of both units would help.

BM4500 has version 1.6

MX5500 has version 2.2S

I read elsewhere on the forum that the BM4500 can be upgraded to version 2.2

Exactly what is the delta between 1.6 and 2.2?
