iFI Audio Uno is a high-performance DAC that reproduces more powerful sound quality and more detailed and realistic sound quality.

■Small enough to fit in the palm of your hand, Uno's cute curved case is made of durable reinforced polymer and is equipped with a sophisticated DAC and headphone amplifier circuit. Upgrade the minimum audio quality of any digital device.

■iFi Uno's USB-C input can be connected to Windows PC, macOS, smartphones and tablets. No separate power supply is required; it receives both power and audio data from the connected device.
■By adding headphones, powered speakers, or an amplifier and passive speakers, you can enjoy the more powerful, more detailed, and more realistic sound quality that everyone wants.

■iFi Uno supports various formats: PCM 32bit/384kHz, full native DSD256, and MQA.

■PCM - Pulse Code Modulation is a file format used by CDs, DVDs, Blu-rays and other digital audio applications.

■DSD - Direct Stream Digital is an audio format with much higher quality than CD quality. DSD64, 128, 256, 512, 1024, the higher the number (sample rate), the higher the quality of the sound recorded. Fully native means that nothing has been changed from the original recording.

■MQA - Master Quality Authenticated is an award-winning audio technology that allows music fans to stream music to their homes, cars, and smartphones while retaining the quality of the original master. iFi Uno allows you to listen to MQA right out of the box.
