iFI aurora Premium Wireless Bluetooth Music System User Manual

Thank you for purchasing the AURORA ‘Wireless Music System.
It was designed for the modern home with future-proofed connectivity. There are multiple ways to enjoy it so please refer to the Quick Start card and/or User Manual to begin.

Setup:

Ensure that the Aurora is placed on a level, non-slip surface.
Never obstruct the unit or place it near any objects or liquids that may damage the unit.

iFi audio suggests downloading and installing the Legacy Player App* on your iOS/Android device first to enable you to operate the playback options on the Aurora.

Automatic Room Tailoring (ART) / Audiophile modes

By holding down the ART button on the front panel for 2 secs, it is possible to alternate between ART or Audiophile modes

ART mode Automatic Room Tailoring in operation. Just input/volume need to be selected.

Audiophile mode ART is switched off. Manual selection of TrueBass and SoundSpace.

All les from 192kHz/32-Bit from MP3 to FLAC can be played directly through the Aurora via the Legacy Player App* or DLNA compatible server software.

WiFi use the Legacy Player App* to connect the Aurora to the local WiFi system to stream Spotify, TIDAL, Napster, QQ Music and many more
Bluetooth Press Bluetooth pairing button and look for ‘iFi Hi-Res audio’.
Airplay Connect via Airplay to enjoy audio playback from iPhone, iPad, and Mac computers.
Source Host USB type ‘A’ Connect an external hard disk drive (HDD), USB memory stick or similar to play music. These must be formatted as FAT32.
Drive must not draw large amounts of power. (A mechanical HDD should be self- powered).
Ethernet/LAN cable* Connect an Ethernet/LAN cable for a wired connection directly from a router or Network Attached Storage (NAS) source. Use the Legacy Player App to stream Spotify (incl. Connect), TIDAL, Napster, QQ Music and many more.
Optical Derive signal input straight from a TV so the Aurora acts as a sound bar.
Coaxial Connect an SPDIF source such as a Blu-ray player.
Micro SDHC card slot Play music les (WAV, FLAC, AAC, Mp3). Supported up to 128GB. This must be formatted as FAT32**.

Notes

Aurora supports UPNP/DLNA.

UPNP support means a wide range of apps can be used for server and control. A few are mentioned below but they are many others. We suggest simply using the one you prefer.
AudioNet Remote Control Point: http://en.audionet.de/apps/rcp/
Linn Open Source Apps: http://oss.linn.co.uk/
dBPoweramp Asset UPNP: http://www.dbpoweramp.com/asset-upnp-dlna.htm

FAT32 – formatting past the Windows 32GB limit

The Aurora reads FAT32 only (not NTFS/ExFat/HPF+)
OS X formats FAT32 regardless of size.
Windows OS by itself is unable to format a drive above 32GB. Third party utilities are required.
“FAT32 Formatter” is a basic portable GUI tool that can format drive larger than 32GB. http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm

Wired is always more preferable to Wireless especially when it comes to reception of higher bandwidth music. If you live in a densely populated area, we recommend the use of a wired network (connect Aurora to router via LAN/Ethernet cable).

Why room correction? Because the room is always the ‘nal component’ in the audio chain. The same system will have a different sonic signature if placed along a room compared to if it was placed across a room. This is mainly due to the sound waves ‘reecting’ differently and this impacts what we hear. For maximum musical enjoyment, we need well thought out room correction for any audio system.

This is EVEN more prevalent with a one-box solution such as the Aurora as all similar one-box products sound like a mono source because they are….a mono source.
Therefore, the Aurora has built-in ‘Auto Room Tailoring’ (ART). Once the unit has been placed in the desired location, all the listener needs to do is to press the ‘ART’ button on the front panel. Using its rear, left and right ultrasonic sensors, the Aurora will automatically set itself up and, after a few seconds, will be ready to play music that lls the room with the spaciousness akin to using a pair of stereo speakers.

How ART works

Using the six ultrasonic sensors, it measures the distance to the walls using ultrasound. The distance affects the low frequency response of the speaker and also our 3D room sound system.
It then applies frequency response corrections and adjustment to the 3D system based upon the distances measured.
Result – consistent realistic sound and a truly spacious sound eld with widely varying placement and no damage wrought by over use of DSP (Digital Sound Processing) as all of this is done in the analogue domain.

The Aurora proudly uses ASP (Analogue Signal Processing) in its room correction system. This means it is uniquely positioned to play music that is unaltered despite using room correction. Most room correction uses DSP.

iFi does not use DSP of this kind in any of its products. The Aurora incorporates sound-matrix technologies that operate entirely in the analogue domain.

Sound Space is one such technology – this combines the drive unit array with a proprietary conguration which adjusts the channel outputs from specic drivers at certain frequencies. It is based upon classic, tried and trusted recording methodologies.

Sound Space is fundamental to the Aurora’s immersive, room-lling performance, enabling the sound stage to extend beyond the connes of the cabinet with expansive width, height and depth. This gives music a tangible sense of scale and space from two, correctly positioned speakers you simply wouldn’t expect from an all-in-one music system

True Bass 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-ring bass radiators, ensures that the Aurora delivers genuine bass with realistic depth and denition. Duallevel 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.

With Aurora, you listen in YOUR way.

The passive radiators work like Helmholz resonators. In order to operate correctly in audible range they cover 25Hz – 60Hz only, they must be tuned to a very low frequency – approx. 18Hz – as the resonance causes a cut in output at the self-resonance frequency. Passive radiators often feature extra weights to tune them.

For our custom passive radiators, we selected a suitably heave material to achieve the correct resonance frequency. As an extra benet, the carbon/ferrite alloy diaphragm, together with the foam layer, is very well dampened. It does not allow the sound from the back of the wideband drivers to escape through the passive radiator and colour the sound.

The carbon/ferrite alloy delivers the required acoustic parameters in a thinner device than other materials would. It is simply the ‘appropriate tech’ for our requirements.

At the heart of the Aurora, lies iFi’s proprietary amp technology ‘Pure Emotion’ – a hybrid circuit design comprising several key stages. The rst of these – the preamp stage – incorporates a Russian 6N3P valve (visible through a window next to the OLED display). This takes the analogue audio signal delivered by the Aurora’s DAC (Digital-to-Analogue Converter)circuitry – based around a chip from ESS Technology’s renowned 32-bit Sabre DAC family – and adds gain in preparation for further amplication, imbuing the sound with pure tonality, open imaging and natural uidity. The resulting low-level signal then passes to the ‘current multiplier circuit’ power amp stage. This is a super high-speed power amplier, one that is bespoke and developed in-house.

The iFi current multiplier circuit is entirely different because the switching frequency is xed at an ultra-high level – around 1.5MHz, hence it has ultra- high resolution. This results in a high level of efficiency, multiplying the current supplied by the valve several thousand-fold, whilst maintaining far greater linearity and lower noise than typical switching ampliers. Coupled to this is a low-pass circuit and a feedback loop, the latter ensuring the output frequency is ideal for the load, and everything is ‘clock-locked’ via iFi’s GMT (Global Master Timing) circuit to ensure unerring precision. Even the audio-grade super-fast power supply is all globally locked in step This ingenious fusion of amp technologies enables a sound that combines purity of tone with a high level of engagement, speed and dynamic gusto, ensuring the emotive quality of music is delivered in full effect.
