Product Introduction

The Titan is a high quality filter designed specifically for power amplifiers. The filter has virtually unlimited power and because of this we are able to achieve a transient of 23,000 watts!

"The Halcro amplifier transformed my system two years ago and the Titan has now transformed the Halcro. Ditto Nova for the DCS." - Iain Lees, Scotland

Overview

A little over two years ago we advocated that power amplifiers benefited from a clean supply This was based upon our research that every component within a system benefited from specific tailored filtering solutions. We felt it was not enough to isolate components from noise on the mains alone. Our research showed that as a component draws power the mains supply is corrupted, basically anything with a power supply would cause this result. Our original SubStation allowed users to specify specific filters for each application. We later advocated larger over engineered isolation transformers for power amplifiers, we called these the 'Qube' and released three versions 1000, 2000 and 4000VA.

A maximum power multiplier was used; if a component drew 500 watts at peak then this figure should be doubled and then doubled again to protect against transient information loss. At the time we felt that they offered the best possible solution. New research breakthroughs show we can do better.

Although there are many things a good isolation transformer can deliver there are, however, several downsides which no matter how hard one tries cannot be overcome. Even though we specified extremely large isolation transformers a reduction in transient response was almost inevitable. This was simply down to various forms of insertion loss within the transformer itself. This is caused by the transformer having a higher impedance than the mains supply typically would.

In order to overcome the limiting factors of isolation transformers we recognised a fundamental shift in thinking was required. Calculations suggest that the typical transient energy available from a typical 13amp mains socket is equivalent to 23,000 watts. In an ideal world, to obtain the best results, the absolute minimum size of isolation transformer if used for filtering would be 23,000 watts. This is obviously a ludicrous suggestion. Although it's anybody's guess what a true mains transient is, we feel this figure stands reasonable scrutiny and maybe a minimum.

It became apparent, almost immediately, that we could not possibly offer this specification; it also became apparent that in order to achieve what we felt was required, we had to.

Features

The new Titan dispenses with isolation transformer technology in favour of a direct-coupled design with a nine-stage series and parallel filter configuration. This is optimised for a high degree of common mode rejection, with the highest possible differential mode rejection compatible with low insertion losses. Great care has been taken to minimise insertion loss at mains frequency. Another asset of an isolation transformer would be a balanced supply, however the new circuit also offers these desirable characteristics, especially at high frequencies where it could be debated it possesses superior performance. To further ensure the greatest possible transient response, enough to realise 23,000 watts potential, two things out of the ordinary have been achieved. Firstly, the minimum constant running ability of the device is rated at over 4,600 watts. Secondly, the unit is fitted with an RCBO, this high tech electronic fusing offers huge transient overloads whilst remaining safe. It also has the added bonus of protecting power cords against long term overload conditions.

Placement

The Titan can be placed either on a dedicated shelf of an equipment support rack or in a position next to or near the power amplifier it supplies. Adequate ventilation should be given to the unit, therefore we would not recommend that it is covered or enclosed in a very tight space. It is also recommended that the unit is not used outside or in areas susceptible to damp conditions.

Equipment coupling

The Titan has been designed specifically for high current applications, especially power amplifiers. Titan is so powerful in terms of transient ability that it is only limited by the network it is plugged into, therefore if possible we would recommend a dedicated supply be installed. You will need to seek the advice of a qualified electrician for this (at time of writing, they would require Part P and Edition 16 of IEEE regulations). At the rear of the Titan chassis are two high quality unswitched outlets these can be used for power amplifiers or other high current devices. The Titan has also been equipped with a Neutrik out to support other specific IsoTek items.

System integration

The Titan should be used with its supplied power cord. Should users wish to change this for their own preferred brand the cable MUST be rated with a minimum of 16Amps. We strongly recommend that a good quality mains cable be used throughout your system. Look for a cable with good conductors, for example oxygen free copper, this cable should also possess a high degree of shielding from RFI
