Advance Paris has been passionately designing products for demanding audiophiles for more than 20 years. 
The UX1 universal source is no exception to the rule. It will satisfy the lover of quality sound on all its sources. The doors of high definition audio will be open to him!

The UX1 is a network player, a DAC, a CD player, a PC / MAC reader via its USB-B X-MOS asynchronous input and a digital DAB / DAB + and FM tuner. 
Whatever the medium of your favorite music - PC or MAC computer, smartphone, tablet, network hard drive, NAS or CD disc, you could enjoy a sound quality of the highest level. 
"Without limit" was our philosophy regarding the design of our universal source. Our engineers have integrated the best technologies with the unique condition that the results obtained results in a soothing listening without aggressiveness of total purity.
The audio output stage, as well as the decoding part, have been particularly cured. Signal conversion is supported by the AK44 AKM converter.

The AK4490 is part of a new generation of high-end 32-bit DACs based on AKM's VELVET SOUND architecture, which has been widely adopted by established high-end audio companies. This technology delivers high-quality sound detail with its low-distortion architecture, in addition to 32-bit resolution digital filter processing. 
The AK4490 supports up to 768kHz PCM and 11.2MHz DSD (Direct Stream Digital), suitable for playback of high-resolution audio sources. Five digital filters are integrated with the DAC thus optimizing the sound reproduction. 
The AK4490EQ is suitable for converting high resolution sound sources that the UX1 masters perfectly.

Combined with our audio stage, this low-distortion DAC (-112dB based on a signal-to-noise ratio of over 120dB) will increase your listening pleasure! 

The UX1 network drive part allows to manage the streaming services (Spotify, Qobuz ...), several thousand local, national and global radio, reading your disco stored locally on your computer or network drive. Compatible with Airplay and DLNA. Multiroom. 
Control of your network drive can be done via the ADVANCE PLAYSTREAM app that can be downloaded from the AppStore and Google Play.

The UX1 has a CD player incorporating the latest generation of servo Tamul ensuring a stable and qualitative CD playback. The solution used combines a 16-bit processor and a 24-bit DSP. It supports CD, CD-R / RW, CD-DA (MP3 / WMA) playback. 

Our universal source is also equipped with an USB-B X-MOS input for direct connection to your PC or MAC computer. This 32-bit / 8-core asynchronous "high-speed" input enables playback of all types of files up to DSD.

In addition to its fixed line output for use with an integrated amplifier or preamplifier, the UX1 can be parameterized as a variable output for connection to a power amplifier or powered speakers. It will then be used as a preamplifier / universal reader. The volume will be controlled from the remote control or via the device itself. 

The UX1 acts as DAC, it is equipped with 3 optical inputs and 2 optical inputs. 
In addition, our player has both balanced (XLR) and unbalanced analog stereo (RCA) stereo outputs as well as two optical and coaxial digital outputs.

The UX1 incorporates a BDD (Bluetooth Direct Digital) port for connecting our X-FTB 01 digital Bluetooth receiver. This receiver integrates the APTX which ensures CD quality from all your sources.
