SPDIF iPurifier2
the Tech
Design Highlights
10MHz Global Master Timing clock
When an audio source transmits the signal, the receiver should know when every
sample arrives. A word clock is necessary to perform it correctly. S/PDIF carries an
embedded word clock signal within the digital data, which allows a receiver to
match the clock with the source and interpret data correctly. Sadly, that enclosed
clock information can be of low quality or degraded by physical properties of a
cable in the pipeline. Even the tiniest frequency difference of 1ppm may translate
into a complete disaster when sending heavy files.
At the heart of SPDIF iPurifier2 lays 10MHz Global
Master Timing clock, which allows for full signal
reclocking. This superior Femto clock
regenerates a stable, high-quality signal
coming from a source device. Thanks to
restored timing integrity the signal delivered
to a receiver is not degraded by physical
properties of a source product or a cable in-
between. It also serves as an internal buffer to
perfectly time the bitstream.
Galvanic Isolation
The optical/Toslink input boasts the premium galvanic-
isolation technology, where electrical circuits are
separated to eliminate stray currents. Audio signals can
pass between galvanically isolated circuits to block i.e.
differences in ground potential or currents induced by
AC power.
Gold-plated copper EMI/RFI shielding
To enhance the audiophile experience, SPDIF iPurifier2 features for
the first time the gold-plated copper EMI/RFI shielding, as found in the
top-notch audio products. Electromagnetic interferences (EMI) in the
audio range manifest themselves from signal distortion to a complete
data loss and system failure. SPDIF iPurifier2’s shielding provides
adequate protection against the ambient electromagnetic fields in the
radio frequency (RFI) spectrum (the part of the electromagnetic
spectrum from 3 kHz to 300 GHz), significantly reducing the
