So yesterday on a visit to my Mother-In-Law I ventured into the loft and retrieved just a few of the 12-year storage items – they actually all belong to my son but there’s no room in his current flat: (ignore the barometer, that’s from another loft!)
And inside the boxes found:
MCL2P with Original Instructions and the 15v cable for powering MCL2AV, plus bottle opener!
Some cables!
Some remotes (needed more of those! ?)
Plus the BC2300 in great external/cosmetic condition
All will be carefully tested over next few days and I will report back any interesting findings!
Also in the MCL2P box – solid plastic plug 42mm long. Any ideas what for?
Perhaps the unused type number label is the MCL2P ‘accessory’, and the plug from elsewhere – the BC2300 perhaps?
I did not expect the 15V cable to be gray, but what do you know. On the other hand these connectors was also used on the Beolit power supplies so they might have had plenty in stock.
The connectors are actually a little strange – the external contact has a small plastic sleeve on it that will slide up and down. I am not sure of the purpose, but it does need a bit of force to push it into the MCL2P socket, whereupon there is a positive ‘click’ once fully inserted:
I had a quick play with the BC2300 last night. It’s a Type 2612 SW1.4 version (one-way IR) with the linear (straight line) CD laser movement. Mixed results:
- Door opened and closed fine first time – very smooth and small gap between panels when closed. Door motion sensors are working fine – less sensitive than my older 2-way BC2300.
- All keyboard buttons work fine – this was my first ever B&O fix when I fitted a new contact foil back in 2010.
- FM and AM radio work fine – FM presets were still stored from 12 years ago and no problems with FM offset (checked with known stations).
- Display a bit dim – but I have seen how to adjust contrast in a YouTube video, hence may attempt this.
- CD not working!!! It tries to play and then I get the < > (no disc) display. I took the back off and put it in test mode. The CD tests all run smoothly will the laser coming on, trying to focus and full linear movement up/down. Trying to play CD in TESTMODE then gives a Focus Error 2. I’ll investigate further but possibly hijack your Ouverture CD thread, as I think it’s the same CD module. In the meantime here’s a picture with the rear cover removed:
Very intererested to hear about the testing of the bottle opener and if that will bring interesting findings
Sadly this will have to wait a few days due to my engaging in a silly concept known as ‘Dry January’! ?
I seem to remember seeing something similar in white before, but can’t remember what it was for.
It’s familiar to me too! Perhaps used to push a hidden reset button, or as a depth guide when drilling holes?
I actually discovered that I have one of these connectors, so I might as well put it on my power supply for the MCL2AV to help secure the connection better.
It’s also the same size as the connector on the Remote Switch, although I replaced mine with a PL plug, I kept the plug, and just managed to find it in my ‘small spares’ box. The ‘extra’ black plastic sleeve is in a fixed position on the remote switch plug:
Have you tried testing the MCl2P yet? I was wondering if the 15V output for the MCL2AV is always on? I guess I has to be on in standby for the MCL2AV to be active, and then the MCL2AV can wake the MCL2P from standby via powerlink.
Just testing it now (prompted by your post, and the fact that my wife is out so I can use the living room!) Yes the 15v (measured 14.75V no load) is always on. One thing that I remember from before is that the BC2300 will not ‘mute’ the MCL2P, despite using a fully wired PL cable. I have a(nother) Passive arriving in the next few days so I will check mute with that also.
Easiest passive speakers to access for test were my Audiorama 8000s, still in their Winter blankets!
CD still not working – must crack on with that task …

Ok good to know.

This might be related to the fact that the MCL2P only use pin 1 in the powerlink connector for powering up. This thread https://beoworld.dev.idslogic.net/forums/topic/powerlink-power-up-vs-speaker-on/ mentions pin 1 as powering up and pin 4 as a mute function on older powerlink speakers.
Looking at the diagram for the powerlink connector on the BC2300 it shows that PIN 1 is connected to 5V supply through a small resistor, and therefor probably not related to the mute function of the BC2300, but still having power when the BC2300 is on.
As the Beolink passive also use pin 1 for powering up I would expect the same result for that, but interesting to hear what you are going to find out when testing it.Also in the MCL2P box – solid plastic plug 42mm long. Any ideas what for?

Was looking for some other MCL2 related stuff and came upon this in the MCL2 installation manual
Is seems to have a very specific purpose for the wall anchors supplied with the MCL2PAs the Beolink passive also use pin 1 for powering up I would expect the same result for that, but interesting to hear what you are going to find out when testing it.
I tried the BeoLink Passive with the BC2300 today, and there is indeed no muting.
Even though it seems a little odd I think I know why the Bc2300 (and probably other) works this way with Pin 1.
To be able to work as a master unit in a MCL2 network (as shown in the above picture) the amplifier for the MCL2 network cannot be muted even though the local speakers are. as listening in link rooms should still be possible.
