Product Introduction

The Nova is our SubStation replacement. Unlike its predecessor there are no complex power requirement calculations to establish prior to installing the unit. Nova also dispense with the SubStations isolation transformer based filtering system which unless properly understood had the potential to restrict the dynamic delivery of an audio system.

The Nova has been designed to represent the ultimate 'front-end' filtration system for up to six components. The unit posses unlimited transient delivery as well as stopping component cross contamination. Although the Nova is suitable for medium to high-end systems, for those audiophiles seeking a cost-no-object power management system use the Nova in conjunction with a Titan (for power amplifiers) for ultimate performance.

Features

The new Nova 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 ensure the Nova has enough power delivery for an entire audio system two things out of the ordinarily have been achieved. 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 Nova can be placed either on a dedicated shelf of an equipment support rack. 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 Nova has been designed specifically for complete audio or audio visual system requirements where high current delivery becomes an issue. Nova 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; we will be posting additional information on this in the future. At the rear of the Nova chassis are six high quality unswitched outlets, these can be used for ALL components including high current devices. Nova is also available in U.S. and European specification, to find a distributor in your country click 'Where To Buy'.

System integration

The Nova 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
