Tech Notes

Soundspace and TrueBass – analogue signal processing
There are plenty of audio products on the market that claim to deliver a big, spacious, three-
dimensional performance from a single box. Many of these use DSP (Digital Signal
Processing) to manipulate the digital data in order to achieve this effect; this is a ‘lossy’
process that has an adverse effect on the purity and resolution of sound.
iFi does not use DSP of this kind in any of its products; instead, the Aurora incorporates
sound-tuning technologies that operate entirely in the analogue domain. SoundSpace is
one such technology – this combines the drive unit array with a proprietary matrix, which
adjusts the output from specific drivers at certain frequencies. SoundSpace is fundamental
to the Aurora’s immersive, room-filling performance, enabling the soundstage to extend
beyond the confines of the cabinet with expansive width, height and depth. This gives
music a palpable sense of scale and space you simply wouldn’t expect from an all-in-one
music system.
TrueBass is another proprietary sound-tuning technology that operates strictly in the
analogue domain. The depth and quality of bass supplied by all-in-one lifestyle systems
often leaves a lot to be desired; the TrueBass system, incorporating the two downward-
firing bass radiators, ensures the Aurora delivers genuine bass with realistic depth and
definition. Dual-level depth control means you can adjust the bass response according to
taste – down to a deeply impressive 27Hz – so that everything from timpani, to a bass
guitar, to an electronic bassline is conveyed with power and poise.
