Regardless of the above issue with audio distortion/hissing, etc. a new driver apparently was released 11/25/15 that contains the fix for these problems. It’s both Windows 7+ and Windows 10 certified.
The mic gain controls have only 36dB of range, which is a bit weak for an audio interface in this price range. For comparisons sake, my Focusrite Scarlett 2i2 has 48-50dB.
The DAC’s (Digital Audio Converters) are pretty good at 24/96. Find out more about how your computer processes sound: Bit depth vs. Sample Rate.
Another potential fix for the pops and clicks issue is that perhaps your USB cable is faulty. Ordering a new one has worked for a lot of people in remedying this issue as well.
A third potential fix for the popping and clicking is to make sure that all external programs are closed as to cut down on the amount of work your PC has to do to keep this stuff running.
The fact that it has 4 balanced 1/4″ outputs is very uncommon for interfaces.
It’s best to have at least 8GB of RAM and an i5 or i7 processor for an interface of this type.
It has XLR, MIDI, and both audio inputs/outputs plus a headphone jack. What is XLR?
Compatible with Linux.
Extremely heavy duty amp with incredibly low latency. Driver update should have fixed the problems mentioned above. Questionable customer support. Headphone output not as strong as expected.
Similarities & Differences
They’re both USB 2.0.
They both have MIDI in/out.
They both have at least 2 channels (in/out).
The 2nd Gen 2i4 supports 24-bit/192kHz sample rates, which results in a DAC that has the capacity to provide better audio quality. The Komplete Audio 6 also supports 24-bit/192kHz.
It appears that the Komplete Audio 6 has lower latency than the 2i4.
The Komplete Audio 6 has 2 more analog inputs than the 2i4 (4 vs. 2).
The Scarlett 2i4 has an edge when it comes to overall sound quality with those award winning preamps.
Aside from a few things, the 2i4 and Komplete Audio 6 are very comparable audio interfaces.
Ultimately I would go with the 2nd generation 2i4 because of it’s slightly better preamps. It is compatible with anything Windows 7 and higher, and anything Mac OS X 10.10 and higher.
1/6/19 Update: It seems as though Generation 2 drivers will work fine with Generation 1 units. Focusrite has updated their entire website and driver download page. Thanks a lot to the fella below for the head up.
I recently had to download a driver update for my 2i2 that did help my immediate issue (Blue Screen) on my computer, so I feel good recommending the 2i4 given how good Focusrite products are. If in doubt, just go with the 2nd gen.
