Portfolio Positioning
Home vs Portable
Audiophile vs General Public

Audio Format LED (kHz)
The LED colour scheme indicates the audio format and sampling frequency received by UNO from the music source.

Green PCM 44.1/48/88.2/96kH, Yellow PCM 176.4/192/352.8/384kHz, Cyan DSD 64/128, Blue DSD 256, Magenta MQA
Connections
1. 3.5mm headphone output to Connect headphones/iEMs
2. Gold plated RCA output to connect to an amp or powered speakers
3. USB-C input: connect PCs, Macs, tablets, smartphones, games consoles, TVs and more.
It needs no power source as it receives both power and audio data from the source it is connected to.

Affordable but still utilizes discrete components
Such as TDK C0G multilayer ceramic capacitors, and inductors from TAIYO YUDEN and MURATA.
Higher cost than commonly used counterparts, but with better sound performance.
For example, low ESR (Equivalent Series Resistance) and high linearity.

CONTENTS

1 x UNO, 1 x USB-A to USB-C Cable, 1 x Quick Start card, 1 x Instruction card
The One you want
Add headphones, powered speakers or an amp and separate speakers and you have what you’ve always wanted
– bigger, bolder, more detailed sound.

DRE (Dynamic Range Enhancement)
iFi's proprietary technology extends the Dynamic Range by 6 dB or more, for an improved listening experience.

In music production, dynamic range means the difference between the loudest and quietest sounds. It’s measured in decibels, or dB for short.
In a single audio track, dynamic range means the dB difference between the loudest and quietest moment in the audio file.
You can think of the dynamic range in a system as the space between the noise floor and the clipping point.
When a sound goes below the noise floor you won’t be able to tell the difference between the signal and the system noise of the medium.
When a sound goes above the clipping point, the tops of its waveform will get abruptly cut off, causing harshness and distortion.
PowerMatch
PowerMatch adjusts the gain of the Uno so that it always functions at the right level for the headphones being used.
OFF - best for lEMs (In-Ear Monitors)
ON - best for on/over ear headphones
