A couple of questions about Roksan K3 integrated

[Linear]

Q1) My 2Qute DAC has a 3v RMS output, this can be too much for some amps, the only specs I can find for the K3 is impedance(47 kohms).
Would the K3 play happily with the 2Qute?

Q2) What's the little square above the mode indicator?

 

[Lurch]

I would say the square is the IR remote signal receiving window.
As to the 3v output, I believe some Chord DACs have an output voltage adjustment option, if yours does then drop it to the standard 2v and all should be good.

 

[Linear]

Thanks Lirch, yes it will be ir for the remote, never though of that.
As for the output voltage, it's non adjustable on the 2Qute, wish it was, so don't have that option.

If the output is too high, then you can put some Rothwell attenuators in line to drop it.

I've got some somewhere I'd be happy to loan you to try out.
Although they may take it too far, 3V to 2V isn't a lot of db.

Yeah, 3v to 2v is about -3.3db.
Rothwell attenuators are -10db, which would give 0.95v.
So could be an option.

I think the ones I have are 14db, so I doubt that would be at all sensible.

Thanks for the offer anyway, its very kind of you.

Also if you're using replaygain or other volume levelling, then you will be well under the 3V max output.

The Roksan website quotes 440 mV for the line input sensitivity.

Thanks David, not sure what that figure means. I doubt it is the max voltage. 1v would be low and I think would make the line inputs incompatible with a lot source devices.

I used attenuators when I had a 2qute. It made the volume control useful as opposed to very loud at a mere touch.

Go for the 10db.

Yes, I do use a volume control before the dac, its one of the reasons I like qobuz. I try not to use it too much because it reduces SNR.

It's insignificant when using 24 bit, but as you're looking at getting a 16 bit DAC then it's definitely a consideration. Suck it and see, Roon does the volume control at 64 bit floating then converts back to your required target bit depth, so it might be ok. My DAC is 24 bit so I find it transparent and a real boon not to have to leap for the volume when I whack on a super loud CD rip.
