iFi SilentPower DC Blocker - Blocks any DC offset, IEC Connector

Product Information

A quite cheap and not very sophisticated filter design, offering a substandard DC-filtration, unless the reqtifier bridge is not spec'd with higher forward voltage diodes. The decoupling is very rrudimentory as well and will do some good, but since no resistor loads are implemented it will not cancel possible resonances. It may seem that we need to know the amplifier power rating, and also that of the transformer. We already know that the transformer will be subjected to considerable inrush current, both to set up the magnetising current and initially charge the filter caps. At this point, use of a soft start circuit (see Project 39) is highly recommended. If a diode is switched in series with the heating element, this reduces the voltage and hence the power (actual power will be almost exactly half). However, by half-wave rectifying the mains in this manner, there is an inevitable interaction with the mains impedance. iFi's approach to noise cancelling in cables uses inverse noise current to cancel out the noise in the mains signal. (Yes, comparable to the tech in noise-cancelling headphones).

Conflict of interest statement: The author declares no conflicts of interest regarding this article. Inrush current can be very much higher than the nominal full power current, so the capacitor(s) require protection against over-current. The simplest has already been mentioned - the diodes that limit the maximum voltage across the caps will also limit the capacitor current. As current increases, so too does the voltage across the capacitors. The diodes will conduct if the voltage exceeds the forward voltage of either pair of the two series diodes. These diodes must be capable of withstanding the maximum peak current expected. This may exceed 50A for a brief period, and again, use a soft-start circuit!Enhanced performance for power amplifiers, offering a consistently clean and efficient power supply. Note that for (e.g. valve) amps and preamps and other devices that draw the maximum current continuously, you cannot (and must not) assume that the capacitance needed can be On to the Nova. iFi has never made an IEC mains cable for home audio components in its nine-year history – until now. The Nova is billed as a specialised power cable with a high-end construction that belies its affordable price point, promising a "serious upgrade over standard mains leads that imbues sound with greater clarity, space and definition".

While the common solution found on the Net appears simple, there's a lot more to it than may seem to be the case. The operation is not intuitive, so while you may think that you know how it works, you could easily be mistaken. Also, beware of snake oil - there are vendors who will make outrageous claims about how their 'gadget' will improve the sound in mysterious ways, often accompanied by a 'technical explanation' that only qualifies as word salad. To apply in store, simply call in to our branch and one of our experienced sales team will guide you through the application.iFi says that by combining the Nova’s sophisticated construction with Active Noise Cancellation II, the firm has delivered a do-it-all clean-power cable solution without the need for a separate mains conditioning device. If the 25% 'rule' is applied, this means that capacitive reactance must be 2 Ohms or less. Remember that we can use Ohm's law to make these calculations - at least up to this point. Calculating the capacitance needed means that we use the capacitive reactance formula, suitably rearranged...

With a continuous current, the capacitance needs to be large enough to support the continuous current. As before, inrush current is not a problem, and the diodes will conduct

In 2010 audiolab began the introduction of its latest full-width 8200 Series components, combining the company’s original ethos of simple, well-constructed ergonomics and crisp, transparent sound with innovative, performance-led design concepts. In the vast majority of cases we will not be able to install the cabinet doors to built-in laundry products as the fittings very rarely match up. We will try our best however if we are unable to do this we will still install connect to plumbing and put the appliance in situ.Deliveries outside of the EU are not subject to 20% VAT and so the 20% tax on items is automatically deducted when you login or register. If a ground loop issue exists, the GND Defender aims to resolve it by disconnecting the loop running through the connected component. By using one or several GND Defenders in a hi-fi system, iFi says that owners can ensure all components are connected to a common ground via a single path, which the should eradicate the resulting hum through the speakers.
