My stupid question for the day - can I temporarily use an Audio Aux cable for a MkII powerlink cable to connect an MCL2 P to my AV7000 while I’m waiting to get my powerlink cable? Will this work? Will it cause damage? Sorry in advance if I’m missing the obvious.

I reckon that it would work fine. 

At worst you may lose auto switch on/off due to lack of pin 8, but I am not convinced that the MCL2P used pin8 to turn on and off anyway as I think this functionality was provided via data on pin 6 and/or 7.

Hi,

it should work flawless.

Pin 8 is the feedback of an active speaker telling the system an Overload Condition.

PIN 6 and 7 are for Speaker Display data.

The MCL2P needs a power on signal on PIN 4! (in contrast to the later BeoLabs)

PIN 1 is not used and theaudio signal comes on PIN 3 and 5.

Hi Dom,

Yes, that will work fine, as long as the Aux cable has all 7 pins wired.

Kind regards, Steve.

Thanks for the help. So it turns out I have a few one way DIN cables that are therefore not fully wired. The amps turn on, but there are no live connections for the left and right audio. So close....Sad

On the other hand, the AV7000 doesn’t detect the presence of the rear channel amplifiers. When I try to configure and calibrate, it stops at the front channels and does not allow the rears to be added. Could the lack of audio wires account for that or does it need the overload pin to be present and wired?

Detecting via the Pin 8 can't be done because the newer Beolabs (4000, 6000, 8000..) don't use the Overload function.

In the manual it says that the AV7000 detects whether rear speakers are connected. Most probably it does this like the Besound 9000. As there are 2 powerlink connectors for 'rear' one dummy Powerlink plug with a resistor ( 1k up to 4.7k) between Pin 2 and Pin 1. should do the trick. The MCL 2P then connected with a fully wired ( Wink ) AV cable to the other rear powerlink connector.

I tried to just plug a 2.2k resistor into the socket, but that didn’t work. I hooked up a spare Beolab 2500, and even unpowered, it worked. I could now adjust the rear channels. Thanks for the help.
