Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Power Surge protection.

Hi,

Just pull the plugs was not a cynical comment.

I am suprised by the amount of incidents.

Regards

I use these:

for surge protection only. Have a BPT balanced power conditioner for everything but my amps; it may improve the sound a little. Can get a good deal on a Shunyata and may try one of those units.

I have this one.

Does improve the sound, and the power-amps can run on it.

"my system sounds better in the morning just before I go to work. Don`t know if it has to do with "cleaner power" or my ears hear better in the morning".

Ask anyone with a Marshall guitar amp, or other high current valve amplifier, and they will tell you there are certain times of the day when the quality of the sound is distinctly off colour. Early evening is a case in point. I don't think it has anything to do with tired ears (iPod users exempted) as that wouldn't explain why the sound improves again later in the evening.

Isotek sell a power conditioner to counteract this, however they are expensive.

Nor was my response. In areas susceptible to lightning strikes and where there is advance warning, your advice is to be heeded. However, in the even of a lack of adequate warning or the occurance of non-lightning-related events, I have a whole-house surge protector and local surge protectors on the two dedicated lines to the AV equipment.

Since installing the APC S-15, I have become aware of low line voltage on a regular basis at the country house. The S-15 does auto voltage regulation as well as power and signal line filterins plus battery-backup.

Kal,

Your comments have made me consider this topic.

In all my life (in the UK) I have never known personally damage caused by lightning. I have known the voltage to drop by a considerable amount and to cause the frequent failure of light bulbs as the voltage fluctuated but no other damage. I do tend to unplug equipment particularly computers if needed.

Same here. I have an apartment in the city where the voltage is stable (aside from the 2 major regional blackouts) and a 19th century house in the country where the voltage varies daily and brownouts/blackouts are common. In neither place, nor in any prior domocile, have I ever had any equipment damaged by AC voltage fluctuations. I guess buying a pricey plasma started me thinking about this and I have acted based on the emotional need to feel secure and some rational analysis of what equipment would actually do something.

Not everyone will reach the same conclusions.

Kal -

Do you plug your amps into the S-15 and can it take the load? How does the S-15 affect audio and video quality? Thanks!

I use the S15 in the MCH system where the power amp is a Bryston 9B. I also have the rest of the system, except for the subwoofer, on the S15 and the read-out indicates anything from about 35-55% of load capacity. The amp does not seem to be limited in any way I can tell subjectively. In fact, the load indicator does not change much in response to a wide dynamic shift. It does change significantly in response to the picture brightness on the plasma.

In the other system, I use it intermittantly only because I feel less of a need for it in this more stable electrical environment.

Hi all!
With great success I use the Monster Powercenter HTS 5100 Signature, this unit consist of 4 pcs (out of 10) "high-current" outlets for amps or active Meridian speakers. This item both protect my gear against surge peaks, and even massively improve the sound from my system - it introduce more "space" between the musicians and even improve the bass performance! And when it also looks cool in my stereo rack - then I can only recommend it warmly!
