I've just bought a 3rd Gen 18i8 and whole researching it I came across THIS article by Focusrite saying to ONLY connect a mic to the xlr socket, I've always used the xlr from my Line 6 Relay into the XLR input on the Focusrite, I also did the same in stereo from my Helix. I've had all generations of 18i8 and have always done it.
Anyway, I thought I'd better heed their advice and I bought a couple of THESE
If I switch INST on, even with gain all the way down I get hum, even with the guitar volume down.
Any ideas? Should I go back to XLR or get a different adapter or cable? If I use the 1/4 out from my Relay it is fine and works how you would expect. The thing is, I used the 1/4 out to go into my tuner and then into an amp when I want to do that and I have the xlr out permanently connected to my Scarlett. I'm just worried about damaging the mic pre-amp.
If you like to insert a line signal or gitar signal into your interface i would advice you to use a di-box.
You can plug a line signal or instrument into it and it will not only reduce the signal but also change the impedance matching the xlr port.
Your sound will not sound flat and in case of a hum you can use a button on the di-box call ground lift.
It's not about what you got to use .... but how you use what you got...

The Scarlett has dual inputs that can take xlr or 1/4 jack and has pad and instrument functions so you can plug an instrument in directly. I just like it set up how I have it but I'm concerned it will damage the mic preamps. Do you know if it will?
The PAD is switch that normally switches between 2 set values. ( Example: +4 / -10 dB )
If you know what your pad button is doing
You can try that. However the impedance of the two "instruments" are not matching .
The inst. Button is normally used for an electric gitar
Not reducing the sound but trying to match the impedance.
If you like to add something with a "hard" line signal
You should use pad ( if it reduces the signal )
But still i would be very careful with the signal.
I have also the combined ports on my interface
And yes i steer in a louder signal ( direct out signal )
But that is not as loud as a fully steered line signal
