The transceiver is connected to the MCL 2 AV through a bundle of coloured cables. The green one is the cable that gives power to the transceiver.

But it does not give any power.

Your setup differs from mine in the way that I don't have beolab, but instead MCL 2 P + passive speakers.

What is this special PL cable? If have a MkIII powerlink cable connected.

Well that should be fine.

Sorry, that was my only guess.

You need PowerLink mkII, also known as fully wired.

I don't see why the transceiver doesn't work depending on the powerlink cable.

As far as I know, MK II is only for data to beolab speakers?

MCL2P is meant as a linkroom amplifier. It can not activated by powerlink. powerlink sends a signal (5V) on PIN4 to start a speaker, the MCL2P amplifier needs a signal on PIN1. Usually an MCL2P is activated by an MCL2A connected to the speakers sockets (they are the same as SPEAKER 2 out of a Beomaster). MCL2P will activate the Beomaster/Beosound connected via Powerlink. Possible setups:

- Beomaster - MCL2AV - Beolab (or MCL2P with special PL cable, but no speaker-on delay)

- Beomaster - Powerlink - MCL2P - MCL2a(s) - passive speakers

Doesn`t your MCL2AV work at all? I remember when I connected an MCL2A to an old BM3300 everything worked fine but not the LEDs on the IR transceiver....

I'm pretty shure it works with a fully wired PL cable, no need for a special one!

@Nico

Connect the MCL2AV to a Beomasters SPEAKER2 output, then check the following voltages in the MCL2AV:

- on the MCL cable white wire you should read approx. 5V (data from Beomaster)
- on the MCL cable pink wire you should read approx. 8V (supply from Beomaster)

- at DC IN (from MCL2P) you should have approx. 15V

If the transceiver LED is still not lit disconnect it and check if you have 5V (where the green wire was connected)

If there's no 5V check the output voltage of both voltage regulators near DC IN socket.
You should read 12V on the first and 5V on the second one.

If there's 12V but no 5V your MCL2AV is probably broken.

Thanks Gerd,

I'll try this and give you the results.

The drawing you added is exactly my setup. Other repliers argued about the possibility of my setup.

I hope it's not broken, then I have to get a new one, because a broken MCL 2 AV makes the MCL 2 P worthless.
