Interesting.
The reason I lost interest is that I think the device
is crap.
The volume dials don't latch. I set a gain on the Focusrite 18i6 and a
minute later it's off by +-1dB.
The 'rubber controls' effect.
Compared to the other two USB audio-device that I
have, the [preamps of
the] Focursite 18i6 is the noisiest. Measured with a 200 Ohm
termination and jnoisemeter: ~-72dBFS (Flat, RMS) -- the Edirol UA-25 is
at -81dBFS and the Presonus 1818VSL at -84dBFS.
Those numbers by themselves mean nothing, you need to consider the gain
as well. If e.g. the 18i6 has 9 dB more gain than the UA-25 then they
have the same input noise.
That make we wonder which award those 'award
winning' preamps of
Focusrite actually won :)
A marketing award ?
It has gain labels from 0..10 -= other comparably
priced devices have
latched dials properly labeled and calibrated with dB.
If you can trust those dB marks is another matter...
I'm enquiring about this for a friend who needs an USB card to be
used with the RPi, with 4 mic inputs. Application is environmental
noise monitoring AFAIK. All suggestions welcome !
