Speakers will have RJ45 sockets instead of DIN from January

18 replies

Apparently, from January all speakers listed below will no longer have the traditional Powerlink DIN sockets.

Instead, they will be fitted with RJ45 sockets and therefore you will need different Powerlink cables.

Speakers which will be manufacturered with RJ45 sockets are:-

  • BeoLab 2
  • BeoLab 3
  • BeoLab 4
  • BeoLab 9
  • BeoLab 10
  • BeoLab 11
  • BeoLab 4000
  • BeoLab 6002
  • BeoLab 8002

The following diagram shows the connections from an RJ45 to powerlink

What are the implications of this for attaching to non B&O equipment (Airport Express or optical out from an Apple TV for example)?

No implication. It is just change of sockets. The electrical signal will be the same. Stupid change, now there will be a risk of mixing up different signals that could potentially damage the equipment.

RJ45 is used for a lot of other applications these days. But, I sure we will not have to wait long before someone plugs their local area network cable into one thinking its a network connection.

I'm sure I'll get a myriad of posts about this, but I have to ask - what's the point?

If the connection is exactly the same then why bother? To save space? Cost? Is B&O trying to corner the shielded ethernet cable market?

I can't imagine trying to terminate a new converter cable..

I don't know what the point is from B&O's point of view, but I see it immensely easier and cheaper for everyone if you can use all the existing RJ45 installation hardware and even house wiring instead of hunting for (expensive, small series) Powerlink wall plates etc.

Installers (and anyone else) will also save about 95% of their time by using crimp tools to make custom length speaker cables instead of struggling with a DIN and a soldering iron.

You'll need a different adapter cable
- but PowerLink remains an analogue signal
- just the plug will be changed.

Optical is a digital signal - no way.

In Network Link (CAT 7) installations a CAT 6 patch cable RJ45<>RJ45  
between wall outlet / PL distribution module and the speaker
will replace all versions of PowerLink cables.     

This will make it a lot easyer to customize cables, soldering 8 pins
takes a lot more time than crimping a RJ45 plug.

Only true, if the cables of your installation are minimum

S/FTP type - SHIELDED/FOILED TWISTED PAIR cables
 
which can be used as a replacement for ML and PL cables.

It is NOT an ISSUE OF BANDWIDTH why you need CAT 7 for an analogue signal
- IT'S THE SUFFICIENT SHIELDING / SCREENING !

CAT 7 cables will always fulfill this SHIELDING requirements for ANALOGUE USE 
CAT 6 cables in many cases, 
CAT 5/e cables won't be sufficient in most cases. 

 

Hi folks,

With such cables, will it still be needed to put some masterlink cables between both the master and the "slave"?

Here is what I've seen on the web:

You can also send Masterlink over Cat 7, but in this thread we are ONLY talking about Powerlink over CAT 7
