@Mexking

This is perfect information, thanks so much !!!

I will start to re-produce the original BeoGram RIAA preamp.

Fantastic!

That is a way of course. Measuring the slot size, and calculating the other dimensions from there.

Maybe I will post a seperate question for measurements. I guess someone on the forum will have a board, to measure all sizes. If I find those, I will post here what it is.

Thnx

@Chartz

Thanks very much for sharing these pictures! That makes it a lot easier to try to make one myself!

 

Question
Since I do not have a pre-amp board at hand, do you have the outside dimensions of the PCB?

Thanks all for your responses and contributions!

@Matador

I have been questioning that myself too. If I look at pictures of the pre-amp board, it seems it is not unthinkable to re-make it. Even in the same look & lay-out as the original. It even makes me wonder if maybe someone did that … (?)

 

@premiumverum

That’s a good suggestion! I will check with Dillen.

Thanks for referring to Peter Pan’s diagrams Guy, that made it clear!

I like the visual way of understanding the pin layout. In the end, it’s easy to make a mistake if you don’t understand the interpretation of sides: male/female and pin/hole side or solder side.

So a picture like Peter Pan is using, helps a lot:

@Matador

Just to be sure …

When looking at the picture you added about the pin-numbers and what they mean:

1. Is the view of this picture, the male connector from the backside (soldering side)?
2. Are the ground wires (of the input and output cables that I need to combine to the DIN), combined on PIN 2?

I would also be interested, and to know of there’s an English version.

Of course, I understand its Steve’s business.  🙂
But I do not have to know how the cable has been configured internally.

I just want to understand if this is only a Mini-Jack-to-DIN cable …
Or that it comes with something else for the 5-volt/trigger signal.

@Steve: maybe you like to respond to this?

@Steve

Very interesting the Mini-jack to RCA cable also has a trigger signal.

But for my understanding, the trigger signal needs to be 5v on Pin 4.

Where do you get the 5v to be used on Pin 4 to activate the B&O speaker amp to get from stand-by to active? Hoe does that work with this cable?

Did you connect a Powerlink or RCA cable to one of the connectors?

what do you see and hear when you do that?

Great comment Steve.

How does the (for instance) Apple Airport generate a trigger signal for the BeoLab?

 

By the way. Is it possible to see the linked product when your website is temporarily closed?

I understand your not 24/7 available to follow-up on everything. Though I can imagine that you keep all informative parts of your website accessible, and close ordering and contact form. Would that work for you?

Hi Lawso,

1) What do you prefer; a) to have an external device to add streaming capabilities, or b) an internal integrated solution?

2) To which B&O model would you like to add these capabilities?

Thanks for your replies guys!

I mainly wanted to know if the pin 3 & 5 and pin 2 & 4 would work simultaneously. So thanks for confirming.

Concerning the cable … the one I need will look a little bit different. I need to split from DIN to a) mini-jack and b) RCA female. But that’s no issue for me, to make one myself.

Why I would do so > Cause I need the turntable and the cassette deck connected to the BeoSound for both recording, as well as for playing via speakers connected to the BeoSound.

Is it possible to simultaneously:

• Connect a turn-table via the Auxiliary Pin 3 & 5 and play vinyl
• And connect my cassette-deck via the same Auxiliary Pin 2 & 4 and record the music from the turn-table

Comment: I would say so, cause normally with RCA connections this AUX would be two RCA connectors for Line IN, and two RCA connectors for Line OUT. So, isn’t the DIN a combination of these sets of RCA connectors in one plug?

 

Question

Please comment on my ‘Is it possible to simultaneously …’ question.

So here’s an additional question …

Is it possible to simultaneously:

• Connect a turn-table via the Auxiliary Pin 3 & 5 and play vinyl
• And connect my cassette-deck via the same Auxiliary Pin 2 & 4 and record the music from the turn-table

Is this possible?

(Assuming of course that a made a splitter cable which can handle that)

Thnx to all, this is a great experience to have such great responses so quickly on the BeoWorld forum!

Additionally I should mention, the external recorder is non-B&O. It will be a vintage Nakamichi 600 cassette deck.

Not being able to control this external recorder as a B&O device is not an issue. For me it is just important that there is a L & R channel OUT, that I can pick up via the Auxiliary connector on the back of the BeoSound 3200.

So from all your information I conclude it is possible and will work. As long as I use:

• Pin 1 >  Left out
• Pin 2 > GND
• Pin 4 > Right out

As mentioned and described in the response and picture of Matador.

Thanks!

Hi Cavscout,

How sure are you that the leads in your cable(s) are connected to the right pins?
Do you have a scheme of the connections, and where did you buy them? (Did you contact Steven from SoundsHeavely?)

@Solderon29

Thanks for your extensive response and guidance. This is very helpful!
Some clarification questions from my side.

1. For checking the 23v DC at the relay coil … I believe it has 6 pins. Which ones should I use to measure on?
2. You mentioned it possible for the Relay RL1 to stick open. What should I (not) measure when it is stick open? And at which pins should I do the measurement?

For reference, I added a picture showing the bottom of the PCB and the relay pins with numbers.

@Beobuddy

It’s gonna be stereo to mono.
In this case I am not going to link two speakers to a stereo set.

@Pilatomic: thnx!

In the meantime I ordered the Taco TMR 4-4811WI, and I have been able to make a test setup with all connected. This is what happens.

When I turn the system on:

• C5 +/- measure 35v, so that’s fine.
• The Taco output measures +/- 5v, so also fine.

Which means, when I plug in power on the BeoLab 6000, my wireless module gets 5v, and starts booting. Streaming music also works fine after the booting.

Problem

When I stop streaming music, the BeoLab switches back to stand-by (Green LED becomes Red).

But at that moment, the voltage coming from C5, drops from 35v to 30v. This causes the wireless module to reboot, which causes the auto stand-by switch back on (Red LED becomes Green).

Which means, this situation creates a loop. Every time music is stopped, the BeoLab returns to stand-by, which causes voltage drop and the wireless module to reboot, …. and so on.

Question

Maybe C5 is not the right point to take the voltage from.

• Is there any other point where the DC voltage is always available (also in stand-by mode (Red LED), and in a constant voltage?
• Where?
