Ifi Audio UNO

The iFi Audio Uno is a compact DAC and headphone amplifier that easily and efficiently enhances the sound quality of a standard digital source such as a smartphone, tablet or computer. Uno simply connects to your source device via its USB-C input and requires no additional power supply. Add headphones, powered speakers or an amplifier and passive speakers and enjoy rich, accurate sound reproduction-all at a contained price.

One device, three operating modes
The iFi Audio Uno offers three operating modes to suit different usage scenarios. The three buttons on the top of the unit make switching between modes quick and easy. The active mode is illuminated with a blue light.

• Music mode: Enjoy detailed and rich sound reproduction to make the most of your favorite songs
• Movie mode: Increase the clarity of dialogue when watching a movie or series
• Game mode: Improve the clarity of sound effects for total immersion and a better understanding of the environment in your games

Uno, dos, hi-res
The iFi Uno supports different file formats – PCM 32bit/384kHz, fully native DSD256 and MQA.

PCM – Pulse Code Modulation is the file format used in CD, DVD, Blu-ray and other digital audio applications. It’s the next step up from MP3.

DSD – Direct Stream Digital is a very high-quality audio format, better than CD quality. The higher the number (sample rate), the better the recording – DSD64, 128, 256, 512 and 1024. Fully native means that it hasn’t been altered in any way from the original recording.

MQA – Master Quality Authenticated is an award-winning audio technology that enables music fans to stream the original master recording into their home or car. With the iFi Uno you can listen to MQA straight out of the box. Simply connect to Tidal Masters and check the option to stream MQA.

Awesome analogue
The Uno’s analogue circuitry is just as vital to the supercharged sound quality it provides as its digital tech.

The headphone amp feeds a 3.5mm socket at the front, incorporating iFi’s S-Balanced configuration to reduce noise and crosstalk. The stereo RCA output at the rear also benefits from our knack for delivering high-grade audio circuitry in remarkably affordable devices.

All the analogue outputs are gold-plated to resist corrosion and maintain conductivity over time.

Most DACs still use digital volume control – ours is analogue. Why is this special? When you reduce the volume on other DACs you remove data from the song or soundtrack. With analogue volume control, you reduce the volume whilst maintaining the quality.

And finally, there’s PowerMatch – this ensures you always have the right amount of power to drive the headphones you are using.
