Το iFi SPDIF iPurifier2 είναι ένα φίλτρο δεδομένων που αναγεννά ενεργά το ψηφιακό σήμα S / PDIF και αφαιρεί αποτελεσματικά το jitter από το ψηφιακό σήμα. Αυτό το jitter ακούγεται στο ανθρώπινο αυτί λόγω οξύτητας, σκληρότητας, έλλειψης δυναμικής και μερικές φορές αναπαραγωγής μουσικής που είναι κάπως εκτός ισορροπίας. Με αυτό (το iFi iPurifier2) θα απολαύσετε έναν ακουστικό θερμότερο ήχο με λιγότερη οξύτητα, καλύτερη διαφάνεια, περισσότερες λεπτομέρειες, ευρυχωρία και μια ευρύτερη και βαθύτερη σκηνή.

This iPurifier2 regenerates the digital source signal 100% bit perfect. There is no up-sampling or resampling involved and the output signal always retains the same bitrate as the source signal. It supports both 2-channel stereo and surround sound data streams from 16-bit 44.1kHz to 24bit 192kHz. The input and output are either coaxial or optical (via mini-Toslink) so this iPurifier2 also acts as a coaxial to optical and optical to coaxial converter. No matter which S/PDIF standard is available or is preferred, this iFi SPDIF iPurifier2 allows music to sound in its full glory.
Plug your S/PDIF (optical or coaxial) source with the supplied adapter cables into the iFi SPDIF iPurifier2. The incoming signal is precisely re-clocked by use of a Femto Master Clock, actively filtered and sent with a correct 75 Ohm impedance (coaxial) to a digital input on your amplifier or DAC. The coaxial signal is galvanically decoupled to both prevent interference from the digital source component and possible ground loops that is noticeable as a light hum in the background. The casing of this iPurifier2 is fully shielded to prevent unwanted RFI/EMI.
S/PDIF (Sony/Philips Digital Interface Format) is the initial digital output to be available for CD players, DVD players and later also for PCI sound cards. This standard is designed for shorter distances and when transferring the signal, it suffers of relatively high jitter values. Over the years a lot of progress has been made in digital signal processing. In spite of all technological progress, the S/PDIF standard is still widely used in the digital audio world, with all its disadvantages. The iFi SPDIF iPurifier2 removes this with just a cheap and simple intervention.
The signal goes through 4 comprehensive stages – isolation, regeneration, a memory buffer and re-clocking. This restores the industry standard ‘square wave’ which represents the desired signal.
The result is a fully-restored SPDIF signal without jitter. The sound quality now has greater warmth, resolution and dynamic contrast.
Extensive jitter-eradication technologies are applied to the digital stage, including our GMT (Global Master Timing) femto-precision clock and intelligent memory buffer. This represents a total ‘out-of-the-box’ systematic digital solution that solves jitter once and for all.
A galvanically isolated SPDIF output means that electrical circuits are separated to eliminate stray elements – a signal can pass but nothing else. Interference-free audio.
And with added Reclock® and Regenerate® the signal remains true and strong.
We pride ourselves on giving you Bit-Perfect signal transfer. This means the signal remains original and unchanged.
This device ensures a Bit-Perfect transfer which is highly unusual for SPDIF devices. It can handle 44.1 / 48 / 88.2 / 96 / 176.4 / 192kHz; 16 to 24 Bit, DSD, DoP, and even Dolby Digital and DTS.
