Murata regs + Caiman = Problem??

[Gazjam]

Hi Jan,
no, I'm ruiunning a coax cable between my Dac and Touch.
The Bdac uses a linear power supply.
When musics not playing the Dac has a mute circuit in place..silent when that kickes in.

*update*

The noise goes away when I take the standard Touch psu out and swap it for another. I guess somethings happened to the supply over time - no idea what.
Ah well - at least the noise is away.

*update 2*

FedEx delivered my Belkin PF30 today - installing it tonight, so wonder what to expect
For you guys that have one (or three!) in place, what would you suggest as a good way to use it with your kit?

For instance should I still plug my amp into the mains and not the "high current" socket?
If so, whats the best use for the high current one...the telly?

What about the Switched and Always On sockets...?
Stick the Dac and Squeezebox in the "Always On" ones?

I'll be plugging in...:
Plasma telly
Virgin Box
Dac
SB touch
Amp
Router
USB Hard Drive (used for streaming movies to the telly)


thanks.

Hi Gary, i'd try this route as it works for me

The amp i'd plug straight into the mains. I'd plug the TV into the switched socket as not only does that remove standby power but it has it's own filtering (handy as it'll have an SMPS).

Any other devices powered by SMPS connect to the "digital" socket/s. All other devices connect to "analogue" sockets.

I'm not sure the digital/analogue description will be correct as i'm attempting to remember the back of the PF40s.

Hope that helps

Bit confused mark, sorry!

the back panel looks like this:

Ah, ok... Well regard the audio & video filters as seperate. Plug your TV into the high current socket. Anything powered by SMPS into the video sockets (my thinking is most video stuff these days uses SMPS as the norm) & anything with a normal mains PSU into the audio sockets

Your amp into the wall as before.

That's a bit better innit

Cheers Mark

have to say, I would have been happy just for the Belkin having tidied up the mess at the back of my rack, but I never expected the sound improvements Im getting.
My mains must have been crap...

[Reid Malenfant]

Pleased it's made an improvement I can't say i'm surprised though as the filters work both ways, so any junk that any SMPS powered kit will generate will be filtered out (hopefully) by the other filters feeding the kit with a standard PSU

They do a good job of isolation i find, of course they'll still filter crap that's on your ring mains to

Distributed filtering and different filters help a lot, I find. I have two PS Audio Harvesters, a Russ Andrews Silencer and an Isotek Isoplug plugged in around the house.

The Harvesters are excellent for seeing how noisy my mains is: sometimes they appear dead and other times they are flickering madly, absorbing the noise.
