Roon finds the links between your music collection and the millions of tracks available on Internet, so you can start with the music you know, then explore and discover new music. The Mini-i Pro 3 acts as an endpoint in the Roon streaming media system, they transparently discover and connect to Roon without any configuration, and bit-perfect audio is delivered from Roon to Mini-i Pro 3.

Balanced Headphone AM

The Mini-i Pro 3 feature a fully balanced headphone amplifier. This allows the left and right channel signals to pass through a nearly perfect symmetrical amplifier circuit, providing ample headphone output power with low distortion and low noise. The output power of single-ended headphone connection is increased by 50%, and the balanced headphone output is increased by 3 times compared to the previous generation. The addition of a 4.4mm balanced headphone jack makes it easier to connect various popular balanced headphones.

HD Bluetooth & Dual Frequency Wi-Fi

When the Mini-i Pro 3 connected to an LDAC enabled Android device over Bluetooth, up to 24Bit/96kHz high-res audio can be transmitted. The aptX HD technology allows compatible devices to transmit 24Bit/48kHz high-res audio wirelessly over bluetooth. The dual-band Wi-Fi and Ethernet connections enable the Mini-i Pro 3 to have high-speed and stable network access. The enclosed antenna system covers the different bands available on the Mini-i Pro 3 for Bluetooth and Wi-Fi.

MQA Core Decoding and Rendering

MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to easily be streamed. The Mini-i Pro 3 is a MQA full decoder, which enables you to play back MQA audio files and streams without any software decoding, delivering the sound of the original master recording.
