Using a combined Masterlink & Aerial Cable

27 replies

Hi everyone,

Just a quick "spanner" to throw into the works! 😜 Whilst I agree that the combined Masterlink and Aerial cable is a smart idea, I would argue that Powerlink and mains power should NOT be combined together, especially not for long cable runs.

One of the first things you learn when studying electronics (after "don't cut the red wire"!) is that you should avoid running power and signal cables together.  This is for a very valid reason; Powerlink audio and data signals are typically less than 1 volt, whereas mains power can be up to 240 volts depending on the country of use.  Over a length of cable, the 50-60Hz frequency from the power cable will be induced into the signal wires, giving a mid-bass "buzz" through the speakers.  Conventional cable screening does little to reduce this effect.

So, in summary, Powerlink plus mains power within one cable looks nice, but it is not a sensible solution (except as a last resort for very short cables runs).  I don't know if anyone from Bosscomm posts on this forum, but I would be interested to hear what testing has been done on this cable in terms of electromagnetic compatibility (ie. leakage of interference from the power wires into the audio wires).

Who is talking about mains combined with Masterlink/Powerlink ? You are right that you must keep mains well away from signal cables.

I don't know really how you can the power cable separate from the powerlink cables... with mysetup in particular all the wires run from  floor stands and to the beosound for about 3 metres... there is a hum, but it's extremely faint

My dealer says that the Bosscom's are not particularly reliable and not of great quality.

Can anyone confirm this from personal experience?

Actually, Bosscom provide some products to B&O and they are a wholesale distributor, so it is unlikely they will sell products in low volumes.

There is nothing wrong with the quality of Bosscoms products, but they are not very reliable! Make sure to count the products in your order!😜

Just to drag this thread up from the dead...

I have a flat with 3 rooms.  I want to link the main room and my bedroom, but thought I'd wire up the spare room while I was at it.  To get to the bedroom, the easiest way may be to go through the spare room first.

With this cable and some of the Bosscom wallplates, would it be possible to connect these 'serially' - i.e.:

Main Room ----------- Spare Room ---------- Bedroom

Or do I have to run two lengths of this?
