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
