The text on Beocentral i pretty clear that it will only work with a Beomaster 2400-2 https://beocentral.com/beogram4004

Furthermore looking at the diagram for the Beogram 4004 I can see that the data connection use both pin 6 and 7 where normally pin 6 is used for Beograms without Riaa built in and pin 7 for Beograms with RIAA built in

Unfortunately though the white IR transceiver it came with doesn’t appear to be working. I’ve connected it up to the relevant screw terminals but it doesnt light up, or respond to IR commands from my beo4. I have a feeling this issue is to do with the mode the MCL2AV is programmed to.

Ok that is unfortunate. In one of the older MCL manuals it is mentioned that if no IR eye i connected to the MCL2AV and it is connected to a TV it will default to option 2. So maybe try without the IR eye.

I have an IR puck for the beolink passive amp (the one with the timer button) – do you know if this would work on the MCL2AV?

That should work as long as you only connect the three wires for ground, +5V and IR data.

But the fact that the white IR eye does no show any light could also be an indication of some missing voltage. If you have a multimeter you could try to measure if you get 5V between the 5V and ground screw terminals.

There are mentioning of some limitations in the datalink implementation in the Beomaster 6000 here https://beocentral.com/beomaster6000-1980s

If I understand it correctly its about starting the Beomaster from the control panel on the Beocord, so should not interfere with remote control of a record player

As an extra info the Beolink handbook has some pages showing the different versions of the round IR eyes and how the wires are connected for the different connection types

One of my IR eyes does not have labels on the buttons,

I also have one without the lettering, but the buttons are there and working, so probably another front cover that is used when the IR eye is configured with the 3 pin minijack where it only has the IR functionality.

Phono button activates the phono input. It is shift and then radio, not shift and radio at the same time.

While it says phono in the display it is the AUX connection it is activating. So this is by far the easiest way
You can also press shift and the A.Tape. The it will show Tape2.

The PHONO button on the Beolink 1000 should activate the AUX source

Hi all, I bought a beogram 3500 earlier in the year which I have had, up until now, connected to my BS9000, but having seen this thread some months ago, I really liked the idea of being able to remote control the beogram via masterlink 🙂

Glad to hear that it is usefull 🙂

My next goal was to get this accessible on my newer network link products so I connected the 1611 converter to an NL/ML converter, which I configured as a Video Master. And this works! I can Join a playing vinyl from another room and the remote control also works (amazing!).

Very nice. I did a test om something similar at one point where I controlled a Beocord 3500 from my Beoplay V1 TV via the converters and the MCL2AV.

ebnrob wrote:

So I am wondering if the 1611 converter is able to work in “Option 0” with the MCL2AV as it doesn’t trigger the NL converter (the Video master) when play’s pressed on the beogram.

The 1611 does not have option settings but the MCL2AV does. It has option 0, 1 and 2 but these are related to an IR eye connected to the MCL2AV, so might not have effect on what you are trying to achive.

ebnrob wrote:

I just tried adding a mk2 powerlink cable between the 1611 and the MCL2AV in the hope this may do the trick as it shows this connection in the 1611 manual when connected to an Avant ML TV and Aux-link audio system, but disappointingly, it made no difference

The intended use case from B&O for this powerlink connection is as far as I know to be able to use the buttons on a Beocenter/Beomaster/Beosound to ctonrl volume and activate sources when connected to a TV that has the speakers for the system. In those cases option 0 is used for the music system, so that could maybe be the answer for the above question. However as the MCL2AV does not have physical buttons it might not apply in this case.

ebnrob wrote:

So, while still playing, I then pulled the powerlink from the amp and plugged it back into the 1611 powerlink input – and hey presto – it turned the Network link  speaker on and started playing!

That sound odd that it would do that. Earlier in this thread we did some experimenting with the powerlink socket on the 1611 but newer got it to activate anything, but there might be something there…

ebnrob wrote:

So I reckon it’s either a wiring mis-match between the two powerlink sockets (maybe different powerlink versions?) – or the MCL2AV can’t see the 1611 connected to it when powering up, so disables the PL out?

Powerlink has two different action signals, sometimes named power on and mute, but with differences. These are on pin 1 and 4 in the powerlink socket. The Beolink Passive only use pin 1 to start up, and the 1611 converter only has a connection on pin4 of it’s powerlink socket. However in the MCL2AV pin 1 and 4 is connected internally, so there should not be any differences to the signals.

ebnrob wrote:

If I turn the MCL2AV off then on again, the amp triggers on correctly when play is started. So i just tested the powerlink back on the 1611, power cycled the MCL2AV, pressed play.. and the beosound2 turned on an the sound came out! However as with the amp – if I turn the BS2 off, and play the record again – the BS2 did not power up. So something weird is going on with the PL out of the MCL2AV.

There might be something with option 1 or 2 on the MCL2AV,. One of the older MCL manuals says that if an IR eye is connected as well as a TV (which in this case is the 1611 and NL/ML converter) it should be setup to option 1. I all other cases it’s option 2.

Hope this might give some inspiration/help. I have as mentioned a Beoplay 1 and a NL/ML conveter so I might try to do some experiments with that when time allows it.

One thing you can try if you have a datalink Beocenter/Beomaster/Beosound is to connect that instead of the MCL2AV and see how things are reacting

I’m not sure but I might remember that when I tried the Beolab 3500 with the 1611 box it did display the time. But I may be confused with the use of the Beoport that for sure display the time taken from the computer connected to it.

I could not remember to have seen this behaviour in my testing of different setups, but for good measure I just connected a 1611 to a Beolab 3500, and the clock did not show up, so I guess it might have been with the Beolink PC2 you registred that.

Also in the intended use cases from B&O it would connect a Beomaster/Beocenter/Beosound with datalink with a Masterlink network, and i most cases those would have the built in clock. And that should also applies in cases where it converts from a Masterlink Beosound to a datalink Beovision.

Of course I am not sure if there are other outliers without a programmeable clock like the Beocenter 2300 without two way communication

This thread https://archivedforum.beoworld.org/forums/t/20924.aspx also mentions the stop timer.

The last post in the thread is indicating that you might be able to program the timer via a Beovision, but has no further explanation as to how

the passive is green when conecting power, then red. i did tried with fully wire powerlink from beosound4,beocenter9300and beosound core. it just dont start. is there a fuse inside thats easy to access?

There are a couple of fuses inside it according to the diagrams in the servicemanual. Wheether or not they are easy to acces I don’t know.

I would still suggest trying another cable just to be sure that the fault is not there.

Øivind Friksen wrote:

i totally agree with you masterlink/IR-eye as one input and powelink as second input.

I am not quite sure what you mean by second input? It is only possible to use one input at a time, either masterlink or powerlink.

i am waiting a masterlink cable and will try. Do i need the IR-eye or will everything be controlled with beosound 4?

The Beolink Passive will work as an amplifier for passive speakers if connected through powerlink

If conncted with Masterlink it will work as a link room and therefore the IR eye is needed in that case. You can do it that way, and disable the IR eye in the BS4 so you don’t get double controls. I am not sure if all controls will work through the Beolink Passive, for example it has been mentioned in other threads that acces to AUX requires a Beolink Passive to be at a certain software level.

Ok, I must confess that I have not done much timer stuff with B&O things. I seems that both the BC9300 and BS Ouverture has a built in clock that can be adjusted, so of course the showed the time fine.

However that got me looking in the user manual for the BC2300 and I can see mentiong of a stop time where you can choose to stop playback after a certain amount of time. The fact that it has this functionality must mean that it has some clock circitry to make that work. However this does not need a clock showing that correct time to work.

But it is confusing that it shows the wrong time on a connected link speaker. Have you tried to connect it via 1611 and ML to see if it shows the same behaviour?

But that got me thinking: If there is a hidden clock/timer in the newer one-way IR BC2300, then perhaps B&O just got rid of the two-way IR circuitry, hence it’s impossible to adjust the clock or set a timer with the Beolink 5000 remote?  However, MCL equipment does support 2-way IR.  So what about connecting my BC2300 via PowerLink to a BeoLink passive (ML/MCL converter) and connect the speaker terminals by MCL cable to an MCL2A (or 2AV) plus IR sensor, and then see if I can use my Beolink 5000 to adjust the time? I had a quick look at the circuit diagrams and can follow the BC2300 PowerLink pin 6 (also Aux pin 6) to the extra ‘MCL’ pin on the Passive’s Left speaker terminal, and then all the way to the data connection between MCL2A and its IR sensor, so perhaps there is a way to shortcut this process by connecting an MCL IR sensor direct to the BC2300 to give two-way IR?

I can confirm that the datalink signal from Powerlink passes through to MCL, and that MCL2AV works with two way remote when connected to a BC9300 (tested directly through MCL/speaker 2) . It was done to test a MCP6500 that I do not have anymore, so can not test further with two way stuff. I did not try things like clock settings when I did it, and I don’t know if it would be possible to set that from a link room at all?

I can try to connect on of my BL3500’s to my BC9300 or Ouverture and see if the time magicly appears there too.

As far as I can see in the servicemanual for the BS4 it should have the nessecary signals to wake up the BL Passive, although I can’t verify it to be fully implemented.

Maybe try with another cable if you have one. I know I have what should be a fully wire PL cable, but it is missing the connection on pin 1 that is used to wake the BL Passive.

If you have a 7 pin Aux cable that can also be used for testing it

I have done some testing now with  fully wired powerlink cable from BS Ouverture to BL3500. ML turned off in all instances.

MK1 SW 1.0: Speaker is not triggered when I play music on the BS Ouverture, but the BL3500 can join in with a press on the mute button or a source button on the remote. So same as Guy registred in his test.

MK1 SW1.2: No test. I had forgot that it was dead for some reason

MK1 SW 2.0  Same behaviour as SW 1.0, but the speaker died in the proces.

MK2 SW 3.1 Will not active at all. This corosponds fine with my testing with the wireless W1 where only the combination of the special data signal from the W1 and the trigger signal on pin 4 would activate it.

A note on the MK1:

I don’t think it would make sense for the trigger signal on pin 4 to with pin 2 as ground to do anything on a MK1 since pin2 is not connected and pin4 is a signal path for sound

Guy wrote:

When I listen closely I can hear a high pitched whine from the right hand speaker – sounds like a grounding problem so something is not quite right.  Maybe polarity reversed on that channel – does that make any sense?

Both reversed polarity of the sound signal, but also you are putting 5V trigger on pin 4 and 5-12V on pin 1 which are both part of the sound signal path. Also you only have the data shield as ground since pin 2 is not connected in the BL3500.

I thought from the serial numbers Guy had two mk2 units but I could be wrong

MK1 is up to serial number 19343452 and has MCL engraved in the metal underneath the DIN connector. Also I belive they were never produced with higher software version than 2.1, but can be upgraded with the loss of MCL functionality.

I think mine is a Mk1 – it has the MCL socket marked as such.

You got me confused .. between “I can´t get it to trigger” to “sound from both speakers”

I mean that I can’t get it (the BL3500) to trigger (i.e turn on) by operating the front panel of the BC2300 (or by using the remote with BC2300 in A.OPT 2 and BL3500 in L.OPT 0). Conversely, with the BC2300 in A.OPT 0 and BL3500 in L.OPT 2 or 6, I can get the system (BC and BL) to turn on and play through both L&R speakers using the remote, or by pressing MUTE on the BL3500 front panel (which plays the last played source.) So the BL3500 will control the BC2300, but the BC2300 will not control the BL3500.

That is also my experience from earlier testing. If a data signal is available on pin 6 the BL3500 can be activated with remote commands to its own IR receiver and put out sound. If I rember correctly the MK1 can be activated without the data signal, but will not put out sound.

I have just connected my BC2300 to my SW2.0 BL3500 by powerlink, and it’s behaving pretty much as if connected by ML.  I can’t get it to trigger from the BC2300.  I have tried L.OPT 0, 2 and 6 to no avail.

Do you also get sound in this setup? The beahaviour you see control wise is because the data signal is connected the same was as if you were using a ML-MCL converter to convert from powerlink to MCL

@madskp when you re-do the test can you clarify the SW version of the BL3500 that you use just in case it only works with a particular SW. I can try with my Mk1 SW2.0 if required.

I will do. And I can try on both SW 1.0, 1.2, 2.0 and 3.1
