Indeed, the noise floor that I measure is lower than your's. I am still learning how to properly use the interface but what is already clear that I probably need an amplifier/bal-SE converter at the output and attenuator/SE-bal converter for the input to get the best performance out of the unit.

I've got to do some tests and soldering tonight, but I might get a chance to do some loopback comparisons tomorrow to give you an idea of the difference between straight balanced loopback and balanced to SE with TR input cable.

Hi,

Valuable 2i2 information here (in Finnish - Google translation). According to the author, 2i2 gen2 has some improvements and does not suffer from output pin loading (my interpretation). Perhaps floating floating balanced out?

Thanks Anders! It looks like gen 2 interface is significantly improved compared to gen1. I'll experiment with my unit in different regimes and will report here how it performs.

It's a Lynx Hilo, rather expensive if new, but I got a 4 year old used unit last year, which is much cheaper.

I also needed an output amp and an input attenuator to reach the sweet spot, but my soundcard do have these built in so it makes thing a little easier.

Your sound card is in a totally different league than entry level Focusrite 2i2 interface. If you've got it reasonably priced then you are really lucky

Hi Oleg,

How does your 2i2 gen 2 measure over frequency?

Here is my 2i2 (gen 1) loop back at -10 dB for comparison. Not so good over 1kHz as distortion rises rapidly.

Mine is more or less like yours.

Ok, thanks. It seems that 2i2 gen 1 performs as gen 2 when it comes to distortion. Some fixes on gen 2 and 192 kHz operation added.
