Audio T Verdict
The IsoTek V5 Titan is a specialist mains conditioner designed around the demands of high-current equipment such as integrated amplifiers, power amplifiers, active loudspeakers and powered subwoofers.
Its three UK outlets each receive an independent Direct-Coupled power-cleaning network, helping reduce Common Mode and Differential Mode mains noise while limiting electrical contamination passing between the connected products.
The three outlets share a maximum UK capacity of 16A or 3,680W. Titan is therefore designed to provide substantial current handling without placing demanding amplification behind a filter intended primarily for lower-powered source equipment.
IsoTek publishes RFI reduction of up to 85dB, extending down to 5Hz, together with 153,000A instantaneous and 75,000A continuous surge protection.
With System Link expansion, an easy-reset RCBO protection system and an EVO3 Premier C19 power cable included, V5 Titan provides focused mains treatment for the power-hungry end of a high-quality audio or AV system.
IsoTek V5 Titan High-Current Mains Conditioner
The V5 Titan is a three-outlet mains power-cleaning and distribution system developed specifically for equipment with large or rapidly changing current requirements.
Rather than combining source-component and amplifier outlets within one chassis, Titan concentrates entirely on high-current products. Each output socket has its own dedicated low-impedance cleaning network, creating three independently treated power connections.
This makes Titan particularly suitable for systems using a power amplifier with active subwoofers, mono power amplifiers, active loudspeakers or other demanding audio and AV equipment.
16A Is the Shared Total Capacity
The three UK outlets share a maximum total load of 16A or 3,680W at 230V.
This rating is not available independently from every socket and should not be multiplied by the number of outlets.
Three Independent High-Current Outlets
Each Titan outlet connects independently to the internal power-cleaning circuit rather than being wired in a simple sequence with the other sockets.
This is important because connected equipment does not only draw electricity. Its power supply can also introduce Differential Mode noise back into the mains distribution system.
By providing every socket with its own dedicated treatment, Titan is designed to reduce the extent to which an amplifier, active speaker or subwoofer affects the other components connected alongside it.
Designed for Demanding Equipment
Amplifiers and powered loudspeaker systems do not necessarily draw a constant amount of electricity.
The current required can change rapidly according to the programme material, volume, loudspeaker load and internal amplifier design. A suitable conditioner must therefore reduce mains noise while maintaining an appropriately low-impedance power path.
Titan’s Direct-Coupled circuitry is designed around these changing current demands rather than adapting a conventional source-component filter for high-power use.
Suitable High-Current Components
- Integrated amplifiers
- Stereo power amplifiers
- Mono power amplifiers
- Active loudspeakers
- Powered subwoofers
- Home cinema power amplifiers
- AV receivers within the total rating
- Modern televisions where appropriate
16A or 3,680W UK Capacity
The UK V5 Titan is rated at 16A or 3,680W at 230V across all three output sockets combined.
Use the published mains consumption of each connected product when calculating the load. Do not use an amplifier’s watts-per-channel output, as this does not directly state how much electricity it draws from the wall.
The total system consumption must also remain within the ratings of the incoming cable, wall socket and household electrical circuit.
Check the Electrical Consumption
Refer to the equipment’s rear panel, operating instructions or manufacturer specification before connecting several high-current products.
Audio T can help assess the likely total load where the published figures are unclear.
Direct-Coupled Power Cleaning
IsoTek’s Direct-Coupled circuit is designed to provide extensive mains-noise reduction while maintaining very low electrical resistance.
This approach is particularly important for amplification, where a restrictive power path could work against the component’s ability to respond to rapidly changing musical demands.
Titan therefore combines high-current filtering with a circuit architecture intended to remain close to the low impedance of the incoming mains supply.
Revised V5 Circuit Architecture
The V5 generation introduced a substantial redesign of Titan’s printed circuit board and internal topology.
IsoTek increased the circuit-board copper loading by more than 50%, doubled the inductance and raised current-handling capability compared with the preceding design.
The company also revised component tolerances and reduced Direct Current Resistance throughout the electrical path.
Reduced Direct Current Resistance
Direct Current Resistance, commonly abbreviated to DCR, describes the basic resistance presented by a conductor or circuit.
For high-current equipment, excessive resistance can create voltage loss and work against the aim of providing a stable electrical supply.
V5 Titan is designed to combine strong noise attenuation with low DCR, rather than achieving filtering by placing an unnecessarily restrictive network between the wall supply and amplifier.
Common Mode Mains Noise
Common Mode noise appears in relation to earth and frequently includes radio-frequency interference generated by wireless communication and electrical equipment.
Wi-Fi routers, mobile phones, computers, televisions, chargers and switch-mode power supplies all contribute to the radio-frequency environment within a modern home.
Titan’s power-cleaning circuits are designed to reduce this unwanted high-frequency energy before it reaches the connected equipment.
Differential Mode Mains Noise
Differential Mode noise appears between live and neutral and can be introduced by the power supplies inside connected products.
Power amplifiers, active speakers and powered subwoofers can create electrical noise as they draw current from the mains supply.
Providing an independent cleaning network for every Titan outlet helps reduce incoming noise and limit contamination passing between the three connected products.
85dB Published RFI Reduction
IsoTek publishes radio-frequency interference reduction of up to 85dB for V5 Titan under its stated 50-ohm reference conditions.
The filtering is designed to operate down into the lower-frequency region, with IsoTek stating correction extending to 5Hz.
The amount of noise reduction achieved in an individual installation will depend on frequency, source impedance, the incoming mains supply and the connected equipment.
Multiple Filter System
Titan is effectively three dedicated high-current conditioners within one half-width chassis.
Each outlet has its own power-cleaning path, rather than asking three connected products to share one simple filter.
This arrangement is designed to provide electrical separation between the outlets while retaining the high-current capability required by amplification and powered speakers.
KERP Equal-Resistance Power Distribution
KERP stands for Kirchhoff’s Equal Resistance Path.
IsoTek uses this architecture to give each outlet a consistent electrical route through the conditioner rather than connecting the sockets one after another.
This is intended to provide equal resistance and consistent power delivery across the three independently treated outputs.
Fully Star-Earthed Network
The protective-earth connections reference a central point within Titan instead of being passed sequentially between the outlets.
This star-earth arrangement provides a consistent protective-earth reference for the connected equipment.
It is also maintained when another compatible IsoTek product is connected through System Link.
Silver-Plated OCC Internal Wiring
The internal power path uses solid-core Ohno Continuous Cast copper conductors with silver plating.
OCC processing is designed to produce long copper crystal structures with relatively few boundaries, while silver provides a highly conductive outer surface.
This internal wiring is selected to maintain low resistance and high current capability between the mains inlet, conditioning circuits and output sockets.
FEP Virtual Air Dielectric
A Fluorinated Ethylene Propylene helix is wound around the internal conductor before a further FEP layer protects and insulates the assembly.
This reduces the amount of solid insulation touching the conductor and creates what IsoTek calls a Virtual Air Dielectric.
The construction is designed to combine electrical insulation and mechanical stability with a low-dielectric internal power path.
High Copper-Loading Circuit Board
IsoTek uses considerably more copper within Titan’s circuit board than is typical of general electronic products.
This increased copper loading is intended to support high current delivery and reduce resistance through the internal circuit.
The conductive circuit-board paths are silver plated as part of the same low-resistance design approach.
Easy-Reset RCBO Protection
V5 Titan uses a 16A RCBO protection system rather than relying solely on a small wire fuse within the main current path.
The RCBO combines overload protection with residual-current monitoring and provides a much larger electrical contact area than a conventional fuse wire.
If the protection operates, switch off and disconnect the connected equipment before investigating the total load or possible fault.
Do Not Repeatedly Reset the RCBO
Repeated operation may indicate excessive connected load, faulty equipment or a problem with the electrical supply.
Disconnect the system and seek suitable technical assistance where the cause is not clear.
153,000A Surge Protection
IsoTek specifies 153,000A of instantaneous surge protection and 75,000A of continuous protection for V5 Titan.
The sequential protection network is designed to respond progressively according to the severity of an incoming voltage spike or surge.
This may help protect Titan and suitably connected equipment, although no mains product can guarantee protection from every electrical event or a direct lightning strike.
Protection Has Practical Limits
Disconnect sensitive equipment during severe electrical storms where it is practical and safe to do so.
Surge protection should not be treated as an absolute guarantee against lightning or a serious supply fault.
System Link Expansion
A System Link outlet allows another compatible IsoTek conditioner or distribution product to be connected without requiring a second wall socket.
The linked units retain a common star-earth reference, helping create a structured power arrangement for systems using separate source-component and high-current conditioners.
A suitable IsoTek System Link cable is required and should match the connection used by the additional product.
System Link Does Not Increase Available Power
Adding another IsoTek product does not increase the capacity of the wall socket or incoming electrical circuit.
The load of Titan, the linked unit and every connected component must remain within the ratings of the complete installation.
Combining Titan with a Source Conditioner
Titan is designed primarily for amplifiers and powered equipment rather than lower-powered source components.
A complete system can therefore combine Titan with an IsoTek conditioner such as V5 Aquarius or V5 Sigmas, with each product handling the equipment for which its circuits were designed.
System Link can help maintain one wall connection and a common earth reference between the compatible IsoTek products.
V5 Titan
- Power amplifier
- Active loudspeakers
- Powered subwoofer
Source Conditioner
- Network streamer
- DAC or CD player
- Preamplifier or phono stage
16A IEC C20 Mains Inlet
V5 Titan uses a 16A IEC C20 mains inlet.
This requires an incoming power cable fitted with a matching IEC C19 equipment connector, rather than the smaller C13 connector used by many source components.
Do not use an adaptor that bypasses the intended connector or reduces the electrical rating of the incoming connection.
EVO3 Premier Power Cable Included
A 1.5m IsoTek EVO3 Premier power cable with a C19 equipment connector is supplied with V5 Titan.
EVO3 Premier uses silver-plated high-purity copper conductors, FEP insulation and factory-fitted terminations.
The cable should reach the wall socket without being pulled tight, sharply bent or wound into a tight coil behind the equipment rack.
Compact Half-Width Chassis
V5 Titan measures 220mm wide, 147mm high and 350mm deep.
The half-width format allows it to provide specialist high-current conditioning without occupying the full width of a conventional hi-fi component.
At approximately 12kg, Titan still requires a strong, rigid and level shelf.
Black or Silver Finish
The sculpted aluminium chassis is available in Black or Silver to complement different equipment finishes.
The enclosure is designed to provide a substantial mechanical structure for the heavy internal components while presenting a clean exterior with minimal visible fixings.
Allow suitable clearance behind the unit for the C19 incoming cable and three connected UK mains plugs.
Placement and Ventilation
Place Titan on a stable surface with its ventilation openings unobstructed.
Do not install it on thick carpet, inside a sealed cabinet or close to radiators and other significant sources of heat.
The mains plug acts as the primary disconnection device and should remain readily accessible.
DC Blocking Is Not Included
V5 Titan does not remove direct-current offset from the incoming AC supply.
Where amplifiers or active speakers produce persistent mechanical transformer hum caused by mains DC, a compatible DC blocker may be installed before Titan.
The DC blocker must provide sufficient capacity for Titan and every component connected to it.
A Conditioner, Not a Regenerator
Titan passively cleans and distributes the incoming mains supply.
It does not create a new electrical waveform or regulate the incoming mains voltage in the way a dedicated power regenerator does.
Its Direct-Coupled circuits are designed to reduce mains noise while preserving the low-impedance connection required by high-current equipment.
Installation Guide

What Might You Hear?
Reducing mains noise and electrical interaction between high-current products may help a suitably revealing system reproduce low-level musical information more clearly.
Depending on the system and incoming supply, possible improvements can include greater bass definition, clearer separation, a quieter perceived background and more stable stereo imaging.
The scale of any change will depend on the mains supply, connected equipment, existing power arrangement and resolution of the complete system.
