The brand-new SPDIF2 is bang up-to-date with features that lower jitter, lower jitter and lower jitter.
- Super-fast 10Mhz Global Master Timing femto clock
- Tantalum 100uF capacitors x 4; better power supply ripple
- Improved MCU firmware; better performance optimisation
Galvanic-isolation, gold-plated EMI/RFI shielding and iPower (5v) via USB-C all underpin the phenomenal performance of the enlarged unit.
Restoring the Waveform and eliminates all jitter
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 the intelligent memory buffer.
The low-jitter crystal clock has been updated to provide >20dB better performance
Bit-Perfect audio on all fronts
IFi pride themselves 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.
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.
Global Master Timing® + Memory Buffer
GlobalMasterTiming-1 AMR’s Global Master Timing (GMT)/ Memory Buffer System represents a total ‘out of the box’ systematic digital solution that solves the digital SPDIF jitter issue once and for all. The Intelligent Memory System holds a large number of complete audio samples, so it may completely absorb a large amount of variation (jitter and drift) in the incoming signal, while still sending out data at a fixed and precise clock rate, regardless of variations in the incoming clock.
Central to the GMT clock system is an ultra-low jitter, quartz-driven clock system (<300 femto second crystal) capable of producing millions of different frequencies with a precision of better than 0.001Hz. Hence, if the frequency shifts from 192,000.002Hz to 192,000.003Hz over a period of minutes (drift) which is the minimum to be meaningful, the GMT clock will intelligently and precisely track the change. This is a core technology of the SPDIF iPurifier.
