Here are the colours displayed through the 2Qute's glass window, and their related sample rates.

Inside the 2Qute employs technology derived from Chord’s more expensive Hugo DAC. So instead of the off-the-shelf digital decoding circuits used by most other manufacturers you get the latest Spartan 6 version of the company’s proprietary Field Programmable Gate Array technology with 26,368 digital taps – which the company claims contributes to better detail retrieval and musical transparency.
    On the rear, BNC coaxial and USB type-B inputs can accept high-resolution files all the way up to 32-bit/384kHz while an optical input operates up to 24-bit/192kHz. All three will also play DSD64 files while DSD128 can be played via the USB and coaxial. As usual the USB input is plug-and-play for Apple and Android devices while Windows users will need to install the supplied driver to get their machines running with the 2Qute.

The round window on the Chord's fascia changes colour to show incoming sample rate. Green
indicates a 24bit/96kHz rate.

A simple connector switch toggles between the three connections and a single pair of line-level RCA outputs provide connection to the hi-fi.
    Incoming sample rate is indicated by the colour shown in the illuminated window on the top of the chassis. For example, on 44.1kHz files the window glows red while green indicates 96kHz, purple 192kHz and so on. It looks fantastic in use but you’ll probably find yourself referring to the instruction manual on a regular basis at first until you memorise the various colour codes.
