Chord Qutest Disliking Two Active Coaxial Inputs. Input Button Turns Blue

[MintChocChap]

Hello
Seeking some help to understand why the input light turns light blue on my Chord Qutest when I have two active coaxial inputs.

Input 1: PS Audio AirLens streamer over 1m of Chord Clearway RCA to BNC cable
Input 2: Audiolab 6000CDT over 0.5m Audioquest Forest RCA to RCA cable, connecting to the Qutest using an Audioquest RCA to BNC adapter

When both steamer and CDT are switched on, the input light on the Qutest turns light blue, and stays light blue even when switching between the two inputs. Music plays but with a fuzzy crackle… clearly not happy. I have to cut the power off one of the inputs for the other to play properly.

I plan to get another Chord Clearway cable as used for the streamer, but does anyone know why the Qutest is behaving this way?

Thanks in advance

Looks like you are a new member. Welcome to ASR.

The Qutest can be set to Dual Data mode which uses both BNC inputs together. This is for achieving 768 khz rates. Apparently according to the manual if it detects inputs on both BNC connections it switches to dual data mode and the light turns blue. So this is what is happening. I suppose you'll have to continue turning off one of the sources to use the other.

You could connect the Audiolab CD player using toslink optical if you aren't using that input. You could buy one of the inexpensive AQ toslink cables. But you'll get the same results with any optical cable. The Chord says it can do sample rates up to 192 khz over toslink, but with your CD player you would be using 44.1 khz anyway.

Thanks for the warm welcome and advice. Until recently I had only used one coax connection and I'd clearly forgotten the Qutest supports dual inputs for m-scalers. Thanks for the tip! I'm already using the toslink connection for my TV but connecting the CDT to it instead would be the better option for my setup. I appreciate the help!
