Bloody Switch Mode PS....I Think!!!

Geoff

Ask your friendly local dealer to lend you a Chord Co Clearway to try on the screen. This may solve the problem. If it doesn't, try it on one of the sources that's giving you the trouble and see if it fixes the problem there instead.

Of course, if it's a £50 DVD-R machine, it seems a touch silly to be applying a £240 noise suppressor in the form of the Clearway, but what choice do you have???

Thanks for the info. I will see if I can get a "ëuro" version for over here.

Someone else said it might be a sync. problem between the component progressive signal coming from the sources and the Plasma's input board ( the plasma is about 2 1/2 years old Pannasonic).

Regarding the clearway mains enhancer by chord, you can get very similar devices from the likes of rs components for about £40 that are designed to be an inline filterand will probably be about the same size as the clearway and fiited with a short iec flylead on one end and an iec socket on the other. Hope this helps.

This message will be edited change the mains cable, it will have the biggest effect. I know were not supposed to talk about them but they do work and they make a difference.

Guys

Thanks for your helpfull input. I posted this on another thread yesterday and it is appropriate here aswell.

"On the red & white flecks are they running in stripes across the background of the picture?

I had this effect on my plasma and discoverd by accident that it was pickup of interference thru' the mains and/or video signal cable simply from the way they were hanging in relation to radiated fields from god knows where exactly, just when I had almost decided I had a fault in my DVD player . I wiggled and gently moved these two leads around and found a different position for them which got rid of the noise flecks on the picture. I managed to get them propped in that position and have had no trouble since. Incidentally using the ferrite cores clamped around the leads did NOT work. Strange, but worth a try"

So there you go. My topic starter on this thread turns out to be unfair. God this hobby is a nightmare at times.

one thing that may be worth doing before getting any kind of device like a clearway, would be to get hold of a noise sniffer, which basically plugs into a wall socket and amplifies any mains noise within the system. If however you do choose to change you're amins cable, remember that you will probably not be able to fit a wattgate or other large bodied iec into the socket on the plasma, unbless it is mounted on the back panel and faces outwards. There is a dutch based company called kempelektroniks who specialise in mains cables and mains devices. There website is: www.kempelektroniks.com and they should be able to loan you a noise sniffer. If you choose to go for a new cable then i would certainly look into the kemp stuff as theirs is 4core cable which includes an earth drain and is very well put together and is about the same price as the isotek range. I would also check you're video cables for any breaks or kinks in the cable.

Interesting.

I turned everything off last nght after watching a DVD film but forgot to switch off the subwoofer.

My wife was watching terrestrial TV later and I noticed a series of thin diagional lines of dots on the screen. Hardly noticable but there.
I mumbled something about our neighbour probably using a drill in his house repairs. But my wife noticed the diode on the sub. Switching off the sub removed them immediately. It runs a hybrid A/B/D power amp.

I've never noticed this before. Nor the least problem on sound quality with it in use. It always adds to the sound quality on stereo music on high level connections. I've tried many times turning it on and off when listening to judge its effect.

The CRT TV is usually fed by a scart cable from the kit in the rack. On terrestrial TV it is still connected of course, even when not in use.

Like I said "...this hobby is a nightmare at times". Now you ahve me switching sub woofers on and off.

Ah, but Grasshopper. You admitted to turning your sub on-and-off in the past. (if I remember correctly) Isn't your sub one of those with an old-fashioned analogue amp anyway?

There is no indication that my sub is spoiling the music in my system. Endlessly repeated on-or-off testing always produces a slight lift in sound quality. On any source and with any type of music.

But I am not using hair-shirt, paint-stripper speakers any more. Or a "high-end" source. So there may be members out there who claim such hybrid power amps do affect sound quality.

My subwoofer simply offers an advantage which I value well beyond any theoretical downside on sound quality. It took me over thirty years to finally get real bass and I'm not giving it up now! They'll have to pry my sub from my dying fingers.

I didn't realize SVS subs were imported into the UK. Or is that a grey import? And how much was it?

Geoff,

TV gear is quite sensitive to earth loops as well. You often get horizontal or diagonal stripes if your kit isn't earthed correctly.

cheers

They are only available for purchase online. Even in the USA as far as I know. They use Bax for their worldwide distribution.

If you are in the UK or Europe you can take advantage of the low dollar value against the pound & Euro. It makes their subs extremely competitive in price v performance. Downside is the size of their enclosures and lack of demo facilities unless you can find someone local via an AV forum and link up for a listen.

I can't give specific prices in other currencies. Prices are always in dollars which you pay in adfvance with a credit card. Your card is only debitted when the sub is despatched.

You pay for Bax in advance to deliver and then when the sub arrives you pay the driver import tax of about 4% + local VAT on top of the sub price + the air freight charges. So around 22% extra in the UK.

If you go to their website and place an unconfirmed order for a specific subwoofer then enter your home country you will get a fixed price for delivery. Most customers choose door to door rather than local airport.

Their products are aimed squarely at the AV market but much enjoyed by stereo fans as well. All but the smallest PB10-ISD (and their non-active subs) offer high and low level connections, roll-off filters, crossovers etc.
They all use large enclosures and 12" drivers (and large ports) to achieve very high SPLs with low distortion.

This is popular US-based international AV/HT forum with countless happy SVS customers. The directors of SVS post there regularly.

This is the SVS website. Ther service is second to none. Just e-mail them and they will recommend a model based on your stated desires: Room size/music/AV/HT/ usual listening levels. They have a huge library of data. The directors regularly recommned alternative manufacturers products where considered appropriate. Their e-mail sevice is legendary. Some customers exchange e-mails for months before making a final decision.

http://www.svsubwoofers.com/

Sorry for the long monologue. But this is the sort of info asked for again and again by poster after poster on the AV fora when they first hear about SV Subwoofers. It just saves time if you hear all the ins-and-outs in one go.

Favorite subs are the Ultra models for those who can afford them. They have a superior driver, more powerful amplifier and greater dynamic range with lower distortion than the Plus and PCI range.

240 Volt models are supplied as standard to European destinations. It doesn't hurt to specify 240 Volts anyway.

Independant reviews are listed on the SVS website.

I hope this doesn't embarrass Naim's forum policies. It certainly wasn't my intention.
It just gets so boring reading (and writing) exactly the same infomation so many times on the AV fora.

Nime

Thanks for the info Nime.

Regards,
Frank.

Thanks for the comment. As I mentioned with my Plasma it seemed the noise was being picked up due to cable location. I have not had to play with earthing and have not seen the problem since moving the cables so all is well at present.
