Mô tả sản phẩm: iFi DC iPurifier
Với công nghệ thường hưởng từ Abbingdon Music Research, iFi mang đến iFi DC iPurifier, một giải pháp giảm ồn do nhiễu điện cho các thiết bị như DAC, ổ cứng di động, máy chủ media, laptop....nói chung là các sản phẩm sử dụng bộ cấp nguồn SMPS
The DC iPurifier sits in-between the SMPS and the device such as: router, DAC, set top box, media streamer, laptop or desk mixer and with the latest Active Noise Cancellation®technology, from 5 volts all the way up to 24 volts (up to 3.5 amps) the DC iPurifier sharply reduces noise to improve the quality of all the device connected.
Got SMPS? Just add the DC iPurifier
Generic Switch Mode Power Supply designs are noisy – but they were only intended for mainstream use so noise was never a consideration. Just insert the DC iPurifier between the existing noisy power supply and the source; noise is reduced by a factor of 316x to 100,000x.
Be it home or professional audio, this is the most simple and most effective way of improving audio performance from arguably, one of the most noisy sources in a computer audio system.
Active Noise Cancellation® drawn from military radar technology
Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation® (ANC®) audio power system. ANC®technology is now a cornerstone of the iFi USB technology range.
An air defence radar is transmitting at a certain frequency; when the signal bounces off the aircraft, a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, but out-of-phase signal is then generated to cancel out the enemy radar signal.
By generating a signal identical to the noise signal but in the exact opposite phase, it completely cancels all the incoming noise. ANC® is the perfect ‘antidote’ for power supply noise; the bane of USB audio.
Across the audible range, measured noise is improved by 316x to 100,000x or by 50dB to 100dB respectively.
Sonically, the background and inner resolution to recordings is brought to the fore and no longer hidden. Sonics are much smoother, just like how good analogue should be. Nothing comes close.
Ultra wide-band design, effective from 1Hz to above 5GHz
iFi leaves no stone unturned: the DC iPurifier is a ground-up, ultra-wide band design. Effective from 1Hz all the way up to 5GHz, crucially the strongest performance is in the audible range of 20Hz to 20KHz.
Ultra wide-band design, effective from 1Hz to above 5GHz
The DC iPurifier handles 5v through to 24V. Takes up to 3.5A or 84W. For different types of DC barrel connectors, the DC iPurifier works with 5.5 x 2.1mm but also ships with adapters for 5.5×2.5mm and 3.5×1.35mm.
Whatever the noisy power supply, these three fittings cover the gamut of DC barrel connectors.
Professional audio applications typically require a ‘centre negative’ power supply. To lower noise with the DC iPurifier, use a ‘centre positive’ power supply at the input and use the special white ‘inverter’ at the output.
