Thanks Steve - you are the expert 🙂

@Steffen Så havde du alligevel ret!

@kernowman, DoubleU.... Life is a matter of learning 😳

Aux splitter cable ordered this morning from Sounds Heavenly, will post results.

Thanks again all!

Thanks kernowman,

Your cable is on its way!  Let me know if you need any help getting everything set up once it arrives.

Kind regards, Steve.

Thanks Steve for joining. 🙂

Just one more thing to discuss is the PL-MK2-cable you used. The pink (pin 8) is not used. The grey (pin 1) and yellow (pin 4) are used for AUX IN, but are not shielded. Probably not a big problem with such a short distance, but officially they should be shielded. As you stated on your site, you experienced problems with mains hum induced through the input socket when 2 devices are non-battery sources. Could that be the problem?

Hi DoubleU,

Yes, the Aux splitter uses the same cable layup as mk.2 Powerlink, but the centre wire (pink) is not connected when used in an Aux cable.  The short length of the splitter (20cm) means that there are no problems with shielding on the grey and yellow audio out wires, as these have approx. 30-40% shield coverage from the adjacent audio ground wires on pins 2 and 7.

The reason that I suggest not using an Aux splitter to link two mains powered devices into a single Aux socket is not due to shielding, it is due to differences in ground potential that can occur when the outputs of two different mains-powered pre-amp circuits are linked together.  This is not a problem when at least one of the items connected is battery powered (eg. an iPod), as this has a floating ground potential that will naturally rise to match the potential of the mains-powered device when connected.

In practice (although I always recommend the use of shielded cables where possible for unbalanced audio signals), 1-2 volt RMS line level signals can be transmitted over quite long distances (typically up to 10 metres) in most domestic environments without picking up noticeable levels of external radiated interference.

Hope this helps.

Kind regards, Steve.

Crystal clear answer. 🙂

Thanks Steve!

I suppose that both the (from kernowman) wished for 'internet radio module' and the Beolink Converter are mains powered sources.

As far as I have understood what Steve wrote, this might be a problem?

If he would connect an iPhone/smarthone playing netradio there would be no problems?

But he asked for connecting a 'internet radio module'!

Hi Millemissen,

There is no need to worry, as this never seems to cause a problem when one of the two devices connected is a Beolink Converter.  I suspect that this is because the converter is double-insulated (ie. no mains earth connected), hence the audio ground is not held at a fixed potential.

The issues only seem to occur in certain cases, with a few combinations of products.  Good point though! 🤒

Kind regards, Steve.

Cable received and connected and everything works beautifully.

Now have much better radio reception, thousands of channels and in my lounge and kitchen.

Thanks for helping me with this, one happy chappie!

Thanks for posting the result - nice to know that it is working.

In fact it is good news - since it makes it possible to create some setups that we weren't aware of before.

And thanks again to Steve.
