SBooster BOTW AC ECO
Why the BOTW AC?
A stock supplied AC/AC power supply in general is nothing more than a low cost “EL-type transformer” in a casing. The BOTW AC power supply is an upgrade AC-power supply and is designed to ensure the most stable and low noise AC current that is possible with an AC power supply.
A low cost EL transformer has not only the lowest efficiency of all available transformer types, a major drawback is the very poor load regulation of this transformer type. The load regulation is the ratio of the AC output voltage measured with no-load and full-load conditions. With the low cost EL transformer this load regulation is around 20% or worse. The poor load regulation leads to instability and degrades the performance of an audio device significantly.
With the BOTW AC our goal is to ensure the highest load regulation as possible. For this we use a highly oversized audio grade toroidal transformer. The combination of the technical design and large power reserve of this transformer ensures a very tight load-regulation with ditto stability.
With an AC/AC power supply you would expect that the output of the adapter shows a perfect sinewave of 50 or 60Hz: Unfortunately this is not the case. All pollution, that is present on your mains grid, will be present on the output of the AC/AC adapter as well. To prevent, that this mains pollution enters your audio device, the BOTW AC starts immediately with the purification of the AC mains power. The built-in dual stage mains filter with upgraded gold plated audio purpose fuse and earth line choke removes the pollution even before it reaches the transformer.
To make the BOTW AC power supply perfect suitable for turntable applications we have added an electrostatic and high frequent magnetic shielding to the transformer as well. An anti-oscillation circuit with Wima capacitors ensures a stable operation of the BOTW AC power supply regardless the type of AC powered audio device. Last but not least, we use our custom-made 16AWG shielded output cable with gold plated connector pins to ensure a low loss distribution of the purified AC power to your device.
