I wonder if it's possible to use an PURE AV (Belkin) (it's an PF50) with an 4B-SST?
This powerprotector from the brand PUER|AV is an power protector with filters inside. Because the manual says: "Powerline conditioners will not improve the 4B-SST".
Because my english is not that good I don't know if a powerline conditioner is the same as the power console mentioned here?
Hi,
I am not familiar with Pure AV - most powerline conditioners and filters limit the INSTANTANIOUS Current draw (only to mention one issue) to the amplifier. So until we developed the Torus Isolation Power Conditioner
http://toruspower.com/ we did not recommend any powerline conditioners on the market be used with our larger amplifiers.
Here is an explanation (lengthy though it may be) of why we recommend the Torus units.
The concern Bryston had with a lot of power line conditioners available in the market
was that many of them could restrict the current available to the amplifier. An amplifier
can draw very high peak current, and wants to 'see' a very low impedance high
current source from the power line. In fact, we even stated in our owners manuals not
to plug our amplifiers into power conditioners. The Transformer based line conditioners
we tested were too small to supply the peak current required and many of them were
just Filters and did not provide Isolation -(Isolation means there is no mechanical
connection between the outside power grid and your inside system power supply).
Also most of the surge protection was done using MOV’s, which are sacrificial and
eventually will be destroyed with repeated spikes. Other issues with these MOVs is that
they allow much more voltage through before they reacted (typically 300 volts and
higher) and they shunt the voltage spikes to ground.
So we decided to try and develop a powerline Conditioner, Isolation and Protection
unit that would not have the restrictions of the many units currently on the market from
an amplifier performance perspective.
Torus Conditioners are designed to provide 5 major benefits:
1. Very low source impedance and high current for the power amplifier:
Torus Power Isolation units present an incredibly low impedance to the electronics
connected to them. A Single 20A Torus has an output impedance of 0.2 ohms and can
deliver 400A peaks. The 100 amp unit only has .04 Ohms of impedance.
A 200W power amplifier demands 10A RMS current for a 120V line (1200VA) but wants
it at 50A peaks. The wall receptacle can't supply the 50A peaks because of the wall
plugs higher impedance. A Torus Single 20A can supply these peaks easily.
2. Protection from power surges using Series Mode Surge supression rather than
MOV's: Torus Power has the best surge suppression available. It works at 2V above
peak (172V). Most MOV-based surge suppression allows 300V through to your
equipment. MOVs are sacrificial components. Torus units are certified to 6000V, 3000A
at 1000 repeats.
This system also does not shunt the spike to ground as MOV's do and therefore the
ground is not fluctuating all over the place. For a more detailed explanation of this very
important feature please see link -
http://toruspower.com/Documents/PQ02ZSP.pdf3 Total ISOLATION from the outside power grid: There is no electric (ohmic) connection between the outside power grid and the equipment plugged into the Torus and power is transferred magnetically. Magnetic transfer of power eliminates the effect of the source and the line impedance and also eliminates the transfer of DC components to the equipment. Torus is also designed to reduce noise effectively, through a "Low Noise" design method. Torus is capable of filtering noise with the starting rate of 12 dB/decade from 5k Hz to over 1M Hz. Other types of filtering start to work from about 20k Hz with lower starting attenuation rate and also restrict the power transfer because of its series connection nature, therefore limitation in maximum current as well, around 20A.
4. High Power Capability: Most other power conditioners and surge protection systems
out there provide units only up to 20 amps. Torus units are available in 9 different units
from 2.5 amps all the way to 100 amps and 120/240 Volts.
Also we have recently introduced NEMA wall mount units as well, which are placed at
the hydro panel for whole house or whole room powerline Isolation and Protection.
5. Very Low Mechanical Noise: The Torus through ‘LONO’ technology eliminates
audible noise in the power transformer regardless of line conditions, including DC offset
and over-voltage. Noise is quantified and specified to NC curves. Torus products are all
less than NC10
Hope this helps.
