No, there is no gain setting on the XLR3 output.
You feel the different output when you switch the gain button, because the software has some bugs, we have found this problem, and will change it later!
You feel the low gain has a role, is the software to do the attenuation, which is not normal.

Ah, this answers my question I guess. Since it's a bug, I suspect I should run the preamp gain at "medium" level to avoid the software attenuation.

@FiiO do you have any insight on this?

I tested in my colleague's Win11 computer but did not reproduce the same problem. Does the problem only happen with Tidal?
This is the setting we set in Tidal app:

Best regards

Watch a YouTube video (don’t stop it), then launch tidal then close and go back to YouTube. Not every time but it happens enough to really make me want to return the unit. I don’t have exclusive mode on, like other sounds to potentially come through. I do have pass through on though.

Btw I’m an IT professional, computer was custom built by me last month and has a fresh windows install. It seems as if either MQA or exclusive mode hangs the k9 and cycling through inputs or turning off and on fixes it. Even restarting the driver through windows doesn’t fix it.

Sounds like the M17 is ideal over the K9PRO, unless you need more power.

would you think the meze empyrean + sony mdr-z1r would benefit from this "more power"?

I don't know if it's a bug or defective unit, but When I am listening to Youtube music (yes ghetto i know), and then stop it and go to Tidal, no audio comes out. I have to reboot the dac/amp to get it to play on Tidal. SUPER annoying. It's making me want to return this unit. When looking at Tidal, all the settings are correct, but no audio comes out until i reboot.

anyone else have this issue?

I’m having the same issue. I tagged FiiO in the post a page back.

Yeah, it's quite annoying and i'm leaning towards just returning the unit. I have about 7 days before my return policy ends, so hopefully they respond and address this

I returned mine to Amazon today. Between that issue and the optical port not securing cables it wasn’t worth keeping.

Will likely upgrade to an RME Adi 2 Pro FRS B. It’s a lot more expensive but worth it I think.

Anyone measured the power consumption of the K9 Pro when it is turned off only using the front power button? With the switch in the back left on. Curious how much power it draws, also a indicator if its bad for the amp to leave it switched on if its drawing a lot of power.

Did you turn it off with a short or a long multifunction button press? Short means mute, long means standby.

Long of course. I don't expect the short press (mute) to decrease power draw.

 

[ahmonge]

If you long press the standby button, K9 Pro will enter standby mode, at this time, only the linear power supply part and the MCU part inside are working, the power consumption at this time will be less than 1w.

I tried connecting to the K9 Pro using the FiiO Control app when it is in this mode and it connected.. Find it hard to believe it is drawing 1w when the Bluetooth module and the processor unit is still on?

Built-in Bluetooth low energy (BLE) technology allows you to use the FiiO control App to control functions like channel balance, sleep timer, etc. at any time, even when not in Bluetooth mode.

And at standby the processor is virtually idling.

Power consumption is minimal.

That's amazing if true. Will try a watt meter and report back findings.
