Description
IsoTek V5 Corvus 9-way Power Cleaning Board
The IsoTek V5 Corvus 9-way Power Cleaning Board is a compact power cleaning and distribution bar measuring just 380mm in length, 170mm wide and 50mm in height. It features nine individual outlets; these reference back to the central internal PCB. Most power filters of this style join outlet sockets together, running each in series connection. This is an error of judgement as Differential Mode Noise, created by the connected load (your audio components) will cross-contaminate between the outlet sockets. The electrical architecture and design of the V5 Corvus prevents this and is therefore superior.
The IsoTek V5 Corvus 9-way Power Cleaning Board features a unique delta filter topology, ten times greater than the recommended standard, this offers more than 20dB power cleaning at 1kHz (reference 600Ohms), this is then improved to 42dB at 10kHz. Most leading experts agree that 10kHz is where radio frequency interference (RFI) starts to influence performance. This is also linked to an amplifiers ability to reject power supply noise. This electrical engineering ensures class- leading power cleaning performance for both Common Mode (RFI) and Differential Mode mains noise. The printed circuit board (PCB) itself also has twice the standard copper loading and is silver-plated.
This unique circuit delivers clean power to its nine outlet sockets – each one independently isolated to prevent cross-contamination of Differential Mode mains noise. This is combined with IsoTek’s KERP © (Kirchhoff’s Equal Resistance Path) to ensure equal resistance and equal power delivery to all outlets. The internal wiring is of the highest standard, a unique 2sqmm design featuring pure 6n oxygen free copper conductor strands each silver-plated, these offer low resistance and high amperage. An aerospace grade Fluorinated Ethylene Propylene (FEP) dielectric, with very low dielectric resistance is used to protect the conductors as well as giving an ideal conductor contact dielectric for the internal power delivery system.

REMOVES MAINS NOISE
Differential Mode mains noise is created by all electrical appliances – everything with a power supply, in fact. This includes your microwave oven, your television and your computer, as well as every hi-fi component you own.
Common Mode mains noise is often referred to as RFI – transmitted frequencies that surround us but we cannot see. For example, imagine how much data is transmitted by smartphones and tablets; cheap power cables act as aerials (antennas) for these unwanted frequencies.
SINE WAVE CORRECTION
From a high quality audio point of view, mains electricity needs two factors; a nice 50 or 60Hz sine wave supplied from a very low impedance source, without radio frequency noise. The low impedance makes for a near constant voltage regardless of how much power is used in the surrounding area. In reality we can typically expect around 5% fluctuation. The very low impedance of the mains, which is way below 1 ohm at 50 or 60Hz is not maintained when approaching radio frequencies (> 50 ohms > 100 kHz) and acts as an aerial (antenna) inviting RF noise.
IsoTek’s power cleaning circuits are designed to reduce impedance whilst remaining safe as well as correcting well into the audio frequency bands. This is not only a judgment from sound electrical engineering, but it also follows the codes of electrical safety, which are independently assessed.
MULTIPLE FILTER SYSTEM
Many IsoTek products are not just a single power cleaning system but are multiple power cleaners in one convenient chassis. The advantage being that each component in your audio system has own dedicated clean power delivery system. Furthermore, Differential Mode noise, created as electrical devices draw power, is kept to a minimum and the possibility of electrical noise cross contamination between outlet sockets is eliminated.
Many power cleaning systems simply place a standard filter design in a box with all outlet sockets joined together in series one after the other, thus connected equipment cross contaminates and the purpose of the product is lost.
INDEPENDENT SOCKETS
IsoTek products feature outlet sockets that are totally independent from each other; no two outlet sockets being directly connected. This is a critical point for limiting or eliminating the cross contamination of Differential Mode mains noise.
Each socket connects directly back to the PCB and is serviced by IsoTek’s unique power cleaning technologies.
SURGE PROTECTION
Power surges or spikes on the mains supply are generally very bad for any electrical device especially a high quality audio replay system. Power surges occur when there is a boost to the electrical charge at some point in the power lines. This causes an increase in the electrical potential energy, which can increase the current flowing to your wall outlet. This in turn can damage your sensitive audio system.
The IsoTek protection system uses an array of VDRs which offer a cascading level of protection, in some cases over 100,000A. These step in fast and sequentially dependent upon the severity of the encountered power surge or spike. The architecture of the protection circuit extends dramatically and almost instantly when required.
The protection circuit has two primary functions, one to preserve itself and the second to step in gradually as any problem increases, with the ability to act very fast should an extreme condition occur. The protection circuits also protect the filters and the filters assist the protection in the initial stage. Unlike many protection devices these assist sound quality as well as providing protection. Studies suggest this problem is not subtle and is frequent. The disturbing challenge is the 1,000 to 6,000V range. It is likely most protection systems do very little good and probably cause sound degradation.
ADAPTIVE GATING
IsoTek’s unique Adaptive Gating system determines the appropriate level of differential filtration for any connected load. The maximum level of overall power filtration is achieved whilst respecting current requirements.
This system also eliminates Differential Mode noise cross contamination between outlet sockets, as all connected devices will corrupt the supplied clean power upon consumption throwing back Differential Mode noise. It is vital that this noise isn’t allowed to affect another component’s performance.
SYSTEM LINK
Some IsoTek products contain a System Link outlet, this is designed to connect multiple units together, maintaining a stared earth reference, and preserving the need for multiple wall outlet sockets.
In the Mosaic One Series this is particularly useful for joining multiple units together using our System Link cable available in EVO3 Sequel and EVO3 Optimum quality (Neutrik powerCON -> C15/C19).
