Transcripts
hey Julian Kraus here and not too long
ago I reviewed the iconic Steinberg you
are 22 more to the V you are 22 C is the
direct successor so let's have a look at
how this new interface performs and see
if Steinberg has proved it
first let's check out the build quality
the prior generation was known for it's
a very robust build and that hasn't
changed the housing is still the same
full metal construction which makes it
the you are 22c feel very sturdy and
that's also the reason this interface
has quite some heft to it the knobs on
the front of the device turn smoothly
and feel solid with only the big volume
knob having a slight wiggle to it even
though you normally don't see inside the
interface I have to say that this also
looks very good and you have to
appreciate the little details like this
a small clamp which holds the cable in
place and keeps it from flopping around
on and on the solid metal housing in
combination with these smooth and sturdy
knobs make the uart when it you see feel
like a quality product now on the front
of the you are 22 see you can find the
two gain knobs for the two audio inputs
these two inputs are XLR and TRS
composites above the inputs you can find
four LEDs to peak indicators which light
up when the audio signal is clipping one
USB connection LED which turns on when
the interface is connected to a PC and
another LED which indicates if the
phantom power for the two XLR inputs is
turned on or off next to the gain knob
for channel two you also find a high Z
button which lets you toggle the TRS
input on a channel to between a line
level and instrument input so you can
directly connect for example an electric
guitar to the interface new on the you
are 22 C is the mono button which lets
you decide whether you want to monitor
our input one on the left
and input two on the right or if you
like to listen to a mono mix of both
inputs further to the right you also
find a very handy knob which lets you
dial in the exact amount of audio you
will hear from the inputs of your
interface compared to the audio coming
from your DAW of course the you are 22 C
also provides a headphone connector
which in this case is a quarter
in check connector and you can control
the headphone volume with the volume
dial above the connector so the front of
the UART when it you see is very similar
to the you are 22 mark - but Steinberg
made a few small tweaks one of them is
that they made the volume knob bigger
and moved it more to the right outer
edge which i think is a wise choice as
the knobs on the older model we're a bit
cramped the UART when it you sees knobs
are a bit easier to access oh and the
volume knob now lights up when the you
are 22 C is powered on on the back of
the interface you can find it two
balanced quarter-inch connectors for
hooking up stuff like active studio
monitors and the volume of these outputs
is controlled by the big silver knob on
the front which we just talked about you
will also find two MIDI connectors one
input and one output to the left you
have a small cutout where you can attach
a high-security Kensington lock below
that you got the phantom power switch I
personally would have liked to see this
a switch on the front because it is
quite awkward to toggle the switch once
you got everything connected and set up
on the far left on the back of the UART
when it you see you got a USB type-c
connector which is used to connect the
interface to a PC or iOS device as I
already said in my focusrite scarlett
review I encourage manufacturers to use
the new USB type-c connector so it's
nice to see that Steinberg is going this
route as well and one more thing I want
to point out is that this is a true USB
3.0 connection lastly you can also find
a micro USB connector which can be used
to power the interface if the device you
connected the interface to does not
provide enough power through the USB C
connection this means that you should be
able to use this interface with a
something like an iPad or even an iPhone
and of course you also got a switch
which lets you select whether the you
are 22 C is powered wire the USB
connection or from the up
no external power supply enough about
the outside of the device let's dive a
little deeper into the specifications
and see how the you are 22 serially
performs first up sample rate and bit
depth the you are 22 C offers a sample
rate of 192 kilohertz this means that
the interface can capture frequencies
way above the human hearing range and
you can see that in my frequency
response measurement the frequency
response is a very flat with only some
roll-off at the very extremes the high
sample rate might come in handy if you
want to slow down the recording and
pulsed and pull the high frequencies
back into the audible range of course
you can always record with a lower
sample rate like 96 K 48 K or 44.1 if
you like so far so good but what struck
me was the maximum sample rate of 32 bit
many interfaces these days use 24-bit
which can theoretically hold a dynamic
range of around 144 decibels which is
more than enough to capture the entire
dynamic range of this audio face the
dynamic range is the difference between
the strongest and the smallest signal
the interface can capture and you want
this to be as big as possible the you
are 22 C is expected to have a dynamic
range of the mic inputs of 102 decibels
a weighted and of course I measured the
dynamic range of my particular unit
which was even a big bigger
coming in at 102 point 9 DB a that's a
decent amount of dynamic range and a
roughly a 3 decibel improvement over the
U or 22 mark - although compared to
other audio interfaces on the market the
dynamic range is a bit on the lower side
still in practice anything with a
dynamic range of more than 100 DB will
be plenty to work with
what still confuses me a bit is the 32
bit bit depth when you have a look at
these sound settings in Windows the you
are 22 C is reported with a bit depth of
24-bit and when you open up the azure
control panel there is no option to
change the bit depth and there is also
no indication whether the interface is
running with 32 or
if orbits in the end it shouldn't really
matter as explained before the 24-bit
can easily hold the entire dynamic range
of the UART one juicy and a 32-bit
shouldn't bring any improvement here the
only reason for the increased the depth
that came to my mind is that the 32 bits
might be used in the internal DSP which
can apply effects to your audio signal
calculating digital effects were 32-bit
can have an advantage because of the
higher precision but that's just pure
speculation okay let's have a look at
the preamps of the U or 22 C and for
that I will switch to the shure sm7b
because this a mic has a very low
sensitivity meaning that it needs a lot
of gain which brings out the noise of
the preamps now I'm speaking into the
sm7b and you can get a feeling of how
the audio sounds like with this mic
connected straight to the U or 22 C to
get a more scientific reading of the
noise I measured the so called
equivalent input noise of the U or 22 C
which lets you directly compare the
noise of its preamp to preamps in other
devices the you are 22 C has an EIN of -
123 point 3 DB you a weighted and and
this is a bit noisier than what I would
have liked to see in such an audio
interface here you can see the you are
22 C's preamps compared to other audio
interfaces the predecessor the you are
22 mark - did have the exact same amount
of preamp nose and back when I did my
review of this interface I wasn't too
impressed by the preamp noise and sadly
that hasn't changed
don't get me wrong here an EIN of - 123
point 3 DB u is still ok and you can get
low noise recordings
it's just that compared to other audio
interfaces in this class the preamps
simply have a bit more noise and here is
what you can expect the noise floor to
sound like when you connect a shure sm7b
directly to the U or 22 C
and here's how the noise of the you are
22c compares to the noise of other audio
interfaces all recordings have been
equally amplified imposed to let you
hear the noise more clearly but other
than that there was no additional
processing done
people always ask me if this interface
can benefit from something like a cloud
lifter or fed head yes the you are 22c
can benefit from such a device and this
can lower the preamp noise by up to
seven decibels so if you are
experiencing preamp noise with the you
are 20 to see a cloud lifter or FET head
might be the solution for you
next up we'll have a look at the maximum
system gain if this is too low you will
necks out your gain and still don't have
enough game to bring your recording to a
proper level the you are 22 C has a
maximum system gain of around 49 dbfs at
0 DB you and this means that you have
plenty of gain even for low sensitive
dynamic mics so all good while I was on
it I also checked out the mic input
impedance as this can have an effect on
your sound if it is too low but the you
are 22 C has an input impedance of 3.9
kilo ohm and that's totally fine the
year round trip latency is a measurement
of how long the audio interface takes to
put out a signal and record it again the
resulting number is a combined input and
output latency of course the latency
heavily depends on the selected sample
rate and buffer size here you can see
the resulting round-trip latency with a
sample rate of a 48 K and here with 192
kilohertz I have to say these are not
the quickest times I have measured but
they are also far from being the worst
one thing I want to point out is that
which buffer size you end up using
depends on many factors like the
hardware in your PC and also the number
of effects in your project you are
currently working on so take these
numbers more as a rough guideline to
what's possible to achieve with EU or 22
C oh and one more point in the control
panel you can actually see the input and
output latency for a given setting and I
found these numbers to line up very well
with my measurements now a big new
feature of the UART we need to see is
the internal
ESP which stands for digital signal
processing this means that you can
process your audio in the interface
before the sound is even recorded for
example the channel strip effect lets
you dial in some compression and
provides a simpler graphic equalizer
Steinberg claims that the digital
processing is done in real time of
course when I hear such a claim I always
wonder how much latency the processing
really adds so I fed a signal into the
audio input on the U or 22 C which you
can see in yellow and compared it to the
signal coming from the headphone output
which was set to direct monitoring
that's the purple signal here as you can
see the direct monitoring signal of the
UART when it you see has a delay of
about 115 microseconds that's incredibly
quick and of course much much faster
than processing the audio in the PC as
you can see even the fastest around a
trip latency was about 50 times longer
suffice it to say in that the internal
DSP is doing the audio processing in
real time as there is no way you would
ever hear this kind of delay while
making this video I just noticed that
the latency is dependent on the sample
rate lower sample rates will yield in a
higher latency but even at 48 kilohertz
the latency was never longer than half a
millisecond which is still much faster
than processing the audio in the PC I
just wanted to mention it for the sake
of completeness I want to add that when
I activated the channel strip effect the
direct monitoring delay slightly
increased to about 130 microseconds
again and this is an impressive able
amount of delay and it is neat to see
all this processing done so quickly
besides the compression and EQ you can
also find a high-pass filter or flip the
face and of course you can decide
whether you want to record the
unprocessed or processed signal with
your door there are a few more effects
when the DSP software which are guitar
amp simulators I think an amp sim is the
perfect use case for the DSP technology
because it is completely calculated
inside the you are 22 C so there is no
further processing need on your PC and
as my measurements showed before this is
all done in real time I think we talked
quite a bit about the recording
capabilities of the you are 22 C but you
might still ask yourself how good is the
headphone output well I won't go into
details here as I'm going to release a
video soon where I'm comparing the
headphone amp quality of many different
interfaces so subscribe if you don't
want to miss it but I can say that the
headphone output of the you are 22 C
delivers audio with very low distortion
and it has a good amount of power and it
can drive even high impedance headphones
to an adequate listening level one thing
that concerns me though is the high
output impedance of about 91 ohms this
means that the you are 22 C is more
suited to headphones with higher
impedances around 150 ohms and above
with the high output impedance of the
you are 22 C's headphone output the
frequency response can change
considerably when used with low
impedance headphones which in turn will
color the sound many headphones these
days are low impedance and that's why
it's so unfortunate that Steinberg chose
to go with such a high output impedance
on the headphone amp so low impedance
headphones are not a good match for the
U or 22 C when use Drive a for
inaccurate listening experience okay
let's sum this all up
I think the UART when if you see is a
well-built audio interface which has a
very robust feel to it the 192 kilohertz
sample rate allows you to record a wide
range of frequencies even above the
audible spectrum and the bit depth of a
32 slash 24-bit lets you capture a
decent amount of dynamic range but I
must confess with the new model I would
have liked to see a bigger improvement
here don't get me wrong on its own the U
or 22 C is a very capable audio
interface it's just when you compared to
other audio interfaces you start to wish
for a
slightly better preamp and dynamic range
performance one thing I'm also not too
fond of is the high impedance of the
headphone output as this can lead to a
change in frequency response when used
with low impedance headphones on the
other hand I really liked the integrated
DSP of the you are 22 C which can apply
effects in what is essentially real-time
with this feature you can process your
audio with a simple effects like
compression and EQ even before you
record the signal I can imagine that
this is a really handy feature for
streamers which can use the DSP to
process their voice in real time this
way the audio will stay in sync with the
video and there is no additional stress
put on the CPU by any effect because it
is all calculated inside the interface
and of course the integrated guitar amp
simulation can be very useful too
because there is no perceivable delay
with the DSP these effects should feel
very responsive lastly I want to point
out that the whole audio for this video
was of course recorded with EU or 22 C
so this should also give you a very good
indication of what this interface is
capable of that's it for now feel free
to subscribe to my channel and please
give me a thumbs up if you liked this
video and we'll see you all in the next
one
