IFi-audio, the sister company of Abbingdon Music Research (AMR), has released a new version of its d.c. power device, the DC iPurifier2.

Designed to turn noisy d.c. power into quiet d.c. power, you simply insert the DC iPurifier2 in the power line between the supply and the device it’s powering and ifi-audio says all noise on the power line that’s between 1Hz and 5GHz will be reduced by a factor of between 316 and 100,000×. ‘The ifi-audio DC iPurifier2 is a ground-up, ultra-wide band design that leaves no stone unturned,’ said George Poutakidis of BusiSoft, which distributes ifi-audio in Australia. ‘Though it’s effective from 1Hz all the way up to 5GHz, the strongest performance is in the audible range of 20Hz to 20kHz, thanks to its much-acclaimed and award-winning ANC system adapted from military radar defence technology.’

Internally, the DC iPurifier2 uses Panasonic SP-Cap Polymer aluminium capacitors with an ultra-low equivalent series resistance, high-precision metal electrode leadless face resistors and custom operational amplifiers, all of which are protected from EMI by copper-alloy shielding.

As well as reducing noise on the d.c. power line, the DC iPurifier2 also has incorrect polarity detection, which detects if input polarity is reversed and, in the event that it is, activates a red LED. It can accommodate d.c. voltages from 5 volts to 24 volts and comes with d.c. adaptors so it’s compatible with all d.c. connector sizes. Available now, the DC iPurifier2 sells for $149.95 (RRP).
