what's important about a power supply?
- Most understand the difference between A/C or alternating current (mains power) and D/C or direct current (like from a battery) and the importance of supplying the correct one to your equipment, but there are many aspects to consider between what comes into your home and what is providing power to the critical elements of your HiFi or home theatre component.
- The term power supply is quite broad, able to be related to the mains power coming in from the street to the complex task of turning that A/C supply into a perfectly smooth D/C lines to feed the components that make your equipment able to reslove the details many miss.
how can i improve my mains power supply?
- With many cities around Australia having rather substantial fluctuations in the mains power levels, and depending on location the potential for a lot of domestic appliance and industrial fed back noise. With many devices on the market able to either substantially filter out noise and perhaps compensate for minor fluctuations, it makes sense to have some form of protection, or another option is of a more substantial fully regulated power isolation unit, delivering pristine mains power to enable your equipment to perform at thier peak.
- High quality power leads improve the speed of a system and its depth capacity, by shielding from external influences from either cables nearby or the many other radient sources, and having an increased capacity to transfer power removing choking effect of generic mains cables. There is a more dramatic step for those interested in taking it further, by introducing a dedicated power run from the switchboard to your gear does even more to remove any restrictions on your equipments ability to breathe freely.
external power supplies
- External power supplies as we think of them are generally a quite geniric device, and more often with a reasonable level of fluctuation caused by external mains or equipment load conditions they suffer, and this is definitely a place to improve a device that uses one, and in many cases can be retro fitted to any component.
- Your device requires a specific voltage with a minimum current capacity, but as with compact and mass produced products there is a size and cost tolerance, whereas a custom built power supply can be set to a specific voltage with ample current and far more tollerant of mains related fluctuations.
- It is also possible in many cases to remove or significantly reduce the function of a devices internal power supply and instead incorperate a specialy high stability external power supply to ensure critical elements have tha ability to perform at thier best away from the inherent side effects of power conversions.
