First, great that you got it somewhat working on your system 🙂

So it would appear that the PL trigger ‘breaks’ when the standby command’s sent from the video master/NL.

When you say that the standby command is sent from the Video master/NL is that because you have a IR eye connected to the NL/ML converter?

And what happens if you press standby on the Beogram?

Some further findings.. when the MCL2AV isn’t responding to CD on the beo4 if I then send the L.OPT1 command from the beo4 the powerlink out comes back to life and the CD command works again! So does the NL when pressing play on the beogram. It seems the MCL2AV’s option programming gets reset back to option 2 each time the video master puts it in standby 🙁

I am being more and more confused about these option settings on the MCL2AV as it seems that sometimes the 5V trigger is there and sometimes not regardless of option 1 or 2. The idea of it being reset to option 2 i not far of as the MCL system manual 89 90 states that the MCL2AV is reset to option 2 if no IR eye is present, so there could be happening something when the video master communicates with the MCL2AV. Also the newer MCL documentation only mentions option 2 as far a I know, so there could be flaws in how option 1 works/is incorperated in the MCL2AV.

I am trying to think about a way to figure out for sure if the MCL2AV is in option 1 or 2. I might have some ideas for that , but might take a little time before I get to that.

What I don’t understand is how I managed to get it to trigger the NL

Based on my latest test I must say that it in many ways seems inconsistenly how this works, so also not sure if all my previous observations can be trusted. Also my system is not setup permanently except for the Beoplay V1, so can’t say how stable things would work over a longer period of time.

ebnrob wrote:

Were you testing with an ML TV yesterday, or the v1 via the NL converter?

My test yesterday was with my ML VT (BC6-23) as it is in the same room as most of my equipment. The Beoplay V1 is two floors down and is being daily used by my family, and therefore I can not always do testing with that

[Madskp]

Just one more note. When it is working it seems to be consistent to the point where I can set the system in standby and wake up the TV again by pressing play on the Beocord several times in a row. But after a power cut i might need to re initialize.

I did try it, but now I can start the Beocenter 6-23 from the Beocord when the MCL2AV is set top option 2.

To verify if it was actually set top option 2 i tried setting options again with a Beolink 1000, and now the setup seems to work both in option 1 and 2, so I am getting very inconsistent results now.

Furthermore when I cut the power and start up again normally the BC6-23 will not regocnise audio commands before the TV has been turn on to a video source 1 or 2 times. But the activation from the Beocord will not work before I have started the A.mem source a couple of times from the remote. So also a factor here wheeteer it is latency in communication or time for things to make a connection or whatever.

I might also at one point have cut the power to the 1611 only to get the connection going.

At this point I am confused about what is up and down in this and what makes the difference in it working or not working. The options settings on the MCL2AV might not have relevance after all.

Fact. is that it can work, but things might need to be initilized in a certain sequence to work.

Just a follow up on some missing point from earlier:

ebnrob wrote:

I only connected 3 wires from the IR eye/puck as I think I read somewhere else on here the buttons didn’t work. I used an off-cut of a network cable to connect the two directly with the din cable still attached 🙂

Yeah could also do that, but I have already plans for making a plug permanently attached to the MCL2AV so I can easily swicth between IR eye’s when doing stuff like this 🙂 This is a good ocasion to actually doing it. And you are right that the buttons will not work. Me and Guy did some testing of that in another thread about IR eyes

the J1 connection’s broken – do you know if this is this a jumper – or perhaps is it a fuse? It looks like its supposed to be disconnected like that.

It should be like that. From what I have found out it is for enabeling programming of the software chip.

Good to have verified the SW version. Apperently the configuration with the antenna snd speaker plugs was also used with the newer SW and type numbers. Probably a way to use allready made stock of the older type

[Madskp]

Hmm the PCB looks like the older type 2020, but the bottom plate says otherwise. Could you try to lift the blank metal cover. One of the chips in there will probably have a label with the Sw version. This just to check that it really has SW 2.3

OK positive that the voltage is there on pin 4 as it should be, but it should not be there in option 2. I will try to double check that on my MCL2AV if I get the 5V signals in both option 1 and 2. Maybe something to do with the IR eye.

Ok my I might have had issues with bad contact in my earlier measurements because now I get 5V on pin 4 in both option 1 an 2, but not in option 0. So this parts should not be affected by the IR eye.

Ive plugged on of my BL8000 speakers into the MCL (using the same fully wired PL cable) and it turns on okay with music playing out when the BG starts. Changing to both L.OPT1 and 2 makes no difference to the behaviour of the unit – the speaker works with both settings. Tested the voltages on pins 1 and 4 with the multi-meter and both are 5v.

OK positive that the voltage is there on pin 4 as it should be, but it should not be there in option 2. I will try to double check that on my MCL2AV if I get the 5V signals in both option 1 and 2. Maybe something to do with the IR eye.

ebnrob wrote:

Perhaps the PL interface on the 1611 is intermittent.

Maybe, but again I am wondering if the IR eye could have something to say. I can try to test that, but I will have to wire up a plug for that (all my round IR eyes have the 7 pin DIN connector)

However, I have noticed that one of the problems is the PL output (trigger) of MCL2AV.  I did notice the following paragraphs in the ‘extra active speaker kit’ (MCL2AV) setup manual – I just wondered if the last little bit about holding the sensor timer button and pressing AV has any effect on what you are trying to achieve?  Possibly not, but worth a try?

I am not sure I quite understand how it is phrased in the manual, but I remebered something similar from the MCL system manual 89 90 where something similar is used to preprogram the MCL2AV to function with active speakers and local sources or just a MCL2A with passive speakers

However that does only make sense for the older type MCL2AV type 2020 with passive speaker connectors, so unsure if it would have any effect. But might be worth a try.

[Madskp]

Just had a look this morning and pin 1 and 4 is connected internally on the connector PCB on the MCL2AV.

The reason I saw some differences on the 2 pins is that I have an external connector board where I can easier measure voltages, but I dit not use fully wired powerlink cables, so pin 1 did not have connection.

So to sum up. If wakeup voltage is comming out of the MCL2AV it will be both on pin 1 and 4. And since you got the Beolink passive to start up you should also be able to get the signal to the 1611.

Have you tested if the Beolink passive only can start up if the MCL2AV is in option 1? That could proove that you have the correct option setting

[Madskp]

Have you tried to remove the Masterlink cable and see if the TV will power on by itself? Just to rule out where the problem lies

[Madskp]

There is also a short SCART cable connecting the control center to the TV – the control center only has 1 SCART, the TV has two (and I’ve tried both).

I don’t think the scart cable has anything to say in wheeter it will turn on or not. I think the TV part is based on a MX TV and the VCR is a separate unit enclosed in the control Center, and therefor the scart cable need to be there to conenct those two if the VCR is going to be used.

Hope you might get some other input for getting it going

 

[Madskp]

The manuals are on site. I should just look under Beosystem instead of Beovision https://beoworld.org/beosystem-av-9000/

[Madskp]

One of my childhood favorites 🙂 I remember glaring over it in the catalogs with a set of Beolab 8000 as front speakers and Beolab 6000 as rear speakers

Not knowing much about it other than that, but as far as I remember there has to be a Masterlink cable between the TV and the control center base.

Also the Masterlink connection might not be compatible with the newer stuff as it use some of the pins that are unpopulated in the normal masterlink cables.

Regarding Beolink Converters there are a special type for the AV9000 system called 1610 AV9000 Audio kit. I have 4 of them from a lot I bought, but the will only work with the AV9000 system as they get power through the Masterlink cable and do not have a separate power jack. From what I found there are two version of it where those I have has 2 Masterlink connectors and the other type only one. I remember reading a little about it from the old forums when I got those to see if they could be usefull, so try to search a little for those names. I guess AV9000 might give more hits that Beovision 9000.

There used to be some manuals and service manuals for it on the manual section, but it looks like they are not uploaded yet. Maybe Mark @Multicare can help here.

Good luck getting it up and running 🙂

[Madskp]

I tried again with MCL2AV (L.opt 1) – 1611 – BLC ML/NL – Beoplay V1, and now I can press play on the Beocord and get the V1 to start and play the music. So the concept works.

You mentioned in one of your first posts about this that you could get a Beolink passive to start from the MCL2AV. The Beolink passive use pin 1 in the powerlink connector to be activated where most powerlink speakers and also the powerlink port in the 1611 use pin 4 in the powerlink conenctor to be activated.

I thought, based on the diagram in the MCL2 service manual that pin 1 and 4 was internally connected in the MCL2AV so that it should be the same for both. But that might not be the case for the newer MCL2AV (the service manual is for the older type 2020). When I did this last test I did measure different voltages on pin 1 and 4 in the powerlink connection.

What I am trying to get to here is that pin 4 might only be activated in option 4 but pin 1 might also be activated in other options. I did not have more time to look into it today, but will definitely look more into it.

An easier way to test if your MCL2AV is in option 1 and output 5V on pin 4 in the powerlink conenctor could be to connect a powerlink speaker if you ahve one you can easily connect to it

I just tried to set it to Link option 1, but it made no difference. Does the beo4 L.OPT function send the same sequence of key presses that you have to make on the 1000 remote?

It should do the same. However I can not rule out if the use of another IR eye does something to it in regards to the defaulting to option 2 like when no IR eye is present.

The version of my 1611 is 1.3 and the MCL2AV is 2.3 type 2026 which I believe is the same as yours. My MCL2AV has an aerial connection on the right which i’ve not seen in other online photos of it.

Both the same types yes, although I have not seen the MCL2AV with SW 2.3 and also the ariel connection which I thought was only present on the older type 2020 of it.

If you have a multimeter maybe you can measure between pin 4 and 2 on the powerlink connection on the MCL2AV to see if it is putting out 5V when you belive it is in option 1. If not it might not be in option 1

ALso here I can get the TV to start up by pressing one of the source buttons on the BC9300. So this point to the issue being how the MCL2AV relay this local source button commands to the connected TV.

Hi Madskp, Thank you for taking the time to test it with your gear. Much appreciated. I had another play around with it last night with the passive amp connected to the MCL2AV and the 1611 at the ready.I pressed play on the beogram, the amp turned on as expected, and I then pulled the powerlink from the amp and plugged it into the 1611. The NL converter then started playing! But then it didn’t do it a second time, so could have been a fluke. Could it be as simple as the PL port on the 1611 being used as the trigger to start the TV connected to the ML side? After thinking about this some more I wondered if the MCL2AV is detecting whether a speaker is connected to the PL port somehow to determine the mode, which the 1611 doesn’t react to? Did you have the MCL’s IR transceiver wired in when you did your tests? Cheers, Rob.

I think I have found out what it is. When I tested with the MCL2AV I might not have had enough focus on the option settings of that, but then I remembered that the powerlink sockets can only be used in option 1. To verify I tried to measure the voltage between pin 2 and 4 in the powerlink sockets of the MCL2AV, and it only has 5V when it is in option 1, so option 0 and 2 will not make the 5V.

I tried the setup with Beocord 3500 – MCL2AV (opt. 1) – 1611 – Beocenter 6 – 26 again, and when I pressed play on the Beocord the TV turned on and music was comming out of the speakers.

This is a little counter intuitive as the documentation says it should be in option 2 when the MCL2AV has no speakers connected and are connected to a TV, and will also default to option 2  if no IR eye is present.

However hopefully option 1 will do the trick. I can not test with my Beoplay V1 right now, but might be able to a little later if needed

[Madskp]

I would think that you also will need some kind of signal on the mute pin in P57. I think that the principle is that the speaker circitry is being held in a mute state until activated.

I do not have acces to any diagrams of the Avant, so I can not come closer than this. If you still have the other parts and can turn it on you could meassure the voltage on the mute signal when its in standby and when the TV is on

Hello

First of the Wireless 1 has known to be unstable, probably because of inteference from other electronics that use the same frequency 2,4ghz (wifi, Bluetooth, baby monitors, wireless doorbells, microwave ovens etc.) so your milage may vary.

Masterlink to masterlink was not possible in the forst software revision. There is no way to check for the current software version unless you can get a dealer to check it with a servicetool. But units from serial number 19956171 should have SW 2.1 that support masterlink to masterlink. Also be sure to buy a pair that is known to work as different software revisions might not work togheter.

In order for this setup to work you will have to setup the TV as a link room TV that accept audio commands. That will be V.opt 6. You will not need a separate IR receiver.

Hope this is helpfull even though it might not be a optimal solution

[Madskp]
