play00:00

look at them they're tiny

play00:03

hey julian krause here and here i got

play00:05

the zoom ams 22 and ams 24 interfaces

play00:09

i'm going to show you the features talk

play00:10

a bit about the audio quality and if you

play00:12

decide they are for you i'll also help

play00:14

you decide between the two that even

play00:16

rhymes by the way there's also an ams-44

play00:19

which i don't have here because the

play00:20

performance is allegedly quite similar

play00:22

to the ams 24 and i didn't feel like

play00:25

buying the whole lineup so that one is

play00:27

missing here but it exists and it offers

play00:30

more in and outputs and then the ams 22

play00:32

and 24. let's have a look at the

play00:33

hardware and the differences between the

play00:35

ams 22 and 24. on the ams22 you get one

play00:39

xlr and trs combo input which you can

play00:42

plug in microphones or guitars but

play00:44

because this is only one single input

play00:46

you can only plug in one at a time which

play00:48

might be a bit limiting even for a

play00:50

single musician there is a second input

play00:53

which accepts unbalanced line signals

play00:55

with a stereo 3.5 millimeter trs input

play00:58

but to notice that the ams 22 only

play01:01

supports two inputs at a time so you can

play01:04

either use the line level input or the

play01:06

xlr and trs input if you use both at the

play01:09

time the left signal from the line level

play01:11

input is mixed together with the xlr

play01:14

input that could be used for some kind

play01:15

of a mixing functionality but i guess

play01:18

the most of the times you want your

play01:19

channels to be recorded separately on

play01:21

the front of the interface you can also

play01:23

find a 3.5 millimeter headphone output

play01:25

the volume can be adjusted with the

play01:27

volume dial on the top this style

play01:29

simultaneously controls the main outputs

play01:31

on the back so you only have one shared

play01:34

control here on the top you can also

play01:36

find a gain dial which is absolutely

play01:38

tiny but at least a smooth to turn it

play01:41

adjusts at the gain for the xlr and trs

play01:44

combo input the 3.5 millimeter line

play01:46

level input is not affected by the gain

play01:48

dial so if you record via the line level

play01:51

input turn down the gain all the way to

play01:53

not introduce any unnecessary noise i

play01:55

find this a bit strange because while

play01:57

consumer line level signals should all

play01:59

be around a similar level in practice

play02:01

that's often not the case and then it is

play02:04

nice to have a way of adjusting your

play02:05

recorded level with a gain dial but well

play02:08

that's not how it is on the ams 22. the

play02:11

left side of the ams 24 enter 22 feature

play02:14

a switch to toggle phantom power for the

play02:16

microphone and on the right side you can

play02:18

find two more toggles one to enable

play02:21

direct monitoring and the switch for the

play02:23

integrated loopback feature which

play02:25

records the output of the pc as well so

play02:27

that it can be combined with the inputs

play02:30

which is great when you're performing to

play02:32

background music and this should be

play02:34

captured as well on the back of both

play02:36

interfaces you can find two usb

play02:37

connections one for data and the second

play02:40

one if the first connection does not

play02:42

provide enough power with the second usb

play02:44

connection you can help out the

play02:45

interface with a power bank or usb

play02:48

charger to keep the interface portable

play02:50

more about the power situation a little

play02:52

later and lastly you get a main output

play02:54

on the back in form of two quarter inch

play02:56

trs jacks i think it's pretty neat that

play02:59

they crammed in full-sized trs jacks in

play03:01

these tiny interfaces compared to the

play03:03

ams 22 the ams24 is a bit bigger

play03:06

although it is still very small for a

play03:08

two-channel interface here is it besides

play03:10

a presonus audio box go which by the way

play03:13

we will also compare the performance

play03:15

against later in this video on the 24

play03:17

you get two xlr and trs combo inputs and

play03:21

they accept microphone and line level

play03:22

signals although the first input can be

play03:25

switched to accommodate guitar signals

play03:27

with the switch at the top there you

play03:29

also got another switch which lets you

play03:31

control the gain of both inputs with one

play03:33

gain dial which can be really handy for

play03:35

stereo recording where you want the gain

play03:37

to be the same for the left and right

play03:39

channel in the top corner the ams24

play03:41

offers a switch which lets you quickly

play03:43

switch between what zoom calls music and

play03:46

stream mode in music mode the inputs of

play03:48

the interface are recorded separately

play03:50

and in stream mode they are mixed

play03:52

together and presented as one source to

play03:54

the software which can be quite handy

play03:56

for streaming duh you will also find the

play03:59

two knobs to adjust the headphone and

play04:01

main output volume the ams24 features

play04:04

two headphone outputs one of which is

play04:06

controlled with the output a dial and

play04:08

the second one with the output b dial

play04:11

like on the ams 22 the output a dial

play04:13

controls the headphone and main output

play04:15

volume simultaneously and the main

play04:18

output can once again be found on the

play04:19

back the ams 24 has one more secret

play04:22

feature at the bottom

play04:23

a battery compartment fittingly there is

play04:26

a toggle for the battery power on the

play04:28

left side which lets you enable or

play04:30

disable the battery power by the way i

play04:32

tested the runtime with battery power

play04:34

and i got three hours with pretty old

play04:36

and loops rechargeable batteries and one

play04:38

condenser mic connected

play04:40

with the newer batteries and without

play04:42

phantom power three and a half to maybe

play04:44

four hours seem realistic i think it's

play04:46

time to explain the whole power

play04:48

situation because it's not as

play04:50

straightforward as i thought it would be

play04:52

the good news is that both interfaces

play04:54

will work just fine with just one usb-c

play04:56

connection to a pc now the ams 22 sadly

play05:00

did not directly connect to my samsung

play05:01

s20 and i needed to connect the power

play05:03

bank to the second usb input the weird

play05:06

thing is that once it turned on and was

play05:08

connected to my phone i could actually

play05:10

disconnect the power bank and it worked

play05:12

just fine with a single usb connection

play05:14

to the phone this gives me hope that

play05:16

there can be a firmware update in the

play05:17

future which directly enables the

play05:19

communication so that you don't need a

play05:21

power bank with the ams22 for portable

play05:23

use because let's face it that pretty

play05:26

much destroys the whole point of buying

play05:27

a portable interface when you have to

play05:29

log around a power bank to get it to

play05:31

power up check the comment section i

play05:33

will pin a comment if that changes in

play05:35

the future with a firmware update why am

play05:38

i confident that this should work well

play05:40

because the ams 24 does that just fine

play05:43

it can connect it directly to the s20

play05:45

and it instantly works no jumpstart with

play05:48

a power bank needed if my phone would

play05:50

have still not been able to power the

play05:52

ams 24 then i could have used the

play05:54

battery power to get it to work on the

play05:56

ams 22 you certainly don't have this

play05:58

option as there is no battery

play06:00

compartment so i think it is even more

play06:02

important that on this interface it

play06:04

straight away works with a single

play06:06

connection to a phone zoom provides a

play06:08

list of compatible phones on their

play06:09

website and i would check that out

play06:11

specifically if you plan to buy the ams

play06:13

22. alright it is time to have a look at

play06:15

the audio quality generally speaking the

play06:17

audio quality of the mic inputs is

play06:19

decent i noticed that on the ams 22 the

play06:22

frequency response is getting a bit less

play06:24

flat at the maximum gain setting which

play06:27

is definitely not uncommon

play06:29

while in practice i doubt that you could

play06:31

notice this this could have been better

play06:33

in this regard and the zoom shows that

play06:35

this is possible as the ams 24 actually

play06:38

stays much flatter even at the maximum

play06:40

gain setting in terms of distortion both

play06:43

interfaces perform equally well with

play06:45

just a hint showing up at around -90

play06:47

decibels i consider this to be inaudible

play06:50

and wouldn't worry about this although

play06:52

one thing to notice is that on the ams

play06:54

24 the distortion rises towards the

play06:56

lower frequencies technically speaking

play06:58

this is not that great but i would argue

play07:01

again that in the real world it is

play07:03

unlikely that you will hear that here

play07:05

the aim at 22 actually takes the lead as

play07:08

it shows much less of a rise in

play07:09

distortion at low frequencies now what

play07:12

about preamp noise of course you want

play07:14

this to be as low as possible to not

play07:15

hear any noise when you use dynamic

play07:17

microphones with condenser microphones

play07:20

this is really not a concern because the

play07:21

microphone is the limiting fact in terms

play07:23

of noise but if you use dynamic mics you

play07:26

definitely want to have the lowest pre

play07:28

noise possible in my measurements the

play07:30

numbers were fluctuating by about a db

play07:32

depending on which xlr input i was using

play07:35

but on average both ams interfaces came

play07:37

in at around -121 dbu how does that

play07:41

sound like in practice well what a

play07:42

coincidence i'm already using a low

play07:44

sensitive dynamic microphone and this is

play07:47

pretty much a worst case scenario let me

play07:49

be quiet for a second so you can have a

play07:51

listen to the noise

play07:56

floor and here's the noise in comparison

play07:59

to a few other interfaces

play08:19

as you could hear the preamp noise of

play08:20

the ams interfaces is definitely on the

play08:22

higher side it's not completely terrible

play08:25

but to be honest in this day and age i

play08:26

really don't understand why zoom uses

play08:28

high noise preamps as it is pretty easy

play08:31

and cheap to get much lower noise now

play08:33

somebody might add that this can easily

play08:35

be fixed with a fat head or cloud lifter

play08:37

and they would be right but that's

play08:39

additional cost and these days you

play08:41

simply shouldn't need these inline

play08:42

preamps anymore so keep this in mind

play08:44

because if you primarily use dynamic

play08:46

mics and want to get the lowest noise

play08:48

recordings the ams series might not be

play08:51

the best choice

play08:52

again for condenser mics this really is

play08:54

not an issue as the mic is the limiting

play08:56

factor here one last thing about the mic

play08:59

input and specifically about noise is

play09:00

the dynamic range it should be as high

play09:03

as possible so you can leave yourself

play09:04

some headroom to not clip and still

play09:06

achieve a low noise flaw here the ams 22

play09:09

doesn't fare too terribly well with only

play09:11

92 db for easy recording scenarios like

play09:14

speech this is plenty but if you get

play09:16

more dynamic and wanted to

play09:18

simultaneously capture louder and

play09:20

quieter sounds like for example in

play09:22

drumming then the ams 22 might run into

play09:25

its limits the ams 24 while also not

play09:27

perfect is quite a bit better with a

play09:30

dynamic range of 101 db for singing and

play09:33

the like i would say the ams 22 is still

play09:35

completely fine but with more dynamic

play09:37

sources the ams 24 simply performs

play09:40

better in terms of noise the line level

play09:42

input performance is actually very

play09:44

similar to the mic input so i'm just

play09:46

flipping through the graphs here

play09:48

distortion is at a level i consider to

play09:50

be inaudible the frequency response is

play09:52

nicely flat and only in the dynamic

play09:55

range chart we see the same difference

play09:57

in performance again as for the mic

play09:59

input here the ams 24 is simply 10

play10:01

decibels better which depending on the

play10:04

things you record might or might not

play10:06

make an audible difference in noise i

play10:08

already mentioned that i'm a big fan of

play10:09

the trs connectors on these small

play10:11

interfaces so let's have a look at their

play10:13

performance the frequency response is

play10:15

very flat in both interfaces just like

play10:18

we like to see the distortion in both

play10:20

interfaces is at a level where it's

play10:21

audibly non-existent but one thing i

play10:24

noticed is that there is quite a

play10:26

difference in the maximum output level

play10:28

the ams 24 can push a proper 20 dbv

play10:31

professional line level while the ams 22

play10:34

only outputs 4.8 dbv max that's actually

play10:37

more like consumer line level which i

play10:40

wouldn't expect on balanced outputs

play10:42

this can have an impact on dynamic range

play10:44

and low and behold we can see that the

play10:46

ams 22 only sits around 96 db

play10:50

the ams 24 on the other hand achieves a

play10:52

very respectable 107 decibels in

play10:55

practice i don't expect you to hear any

play10:57

noise from the main output of these

play10:58

interfaces but with the ams 24 you can

play11:01

be much more certain of that by the way

play11:03

if your studio monitors have a minus 10

play11:05

dbv to plus 4 dbu switch i suggested to

play11:09

set it to -10 for the ams 22 and plus

play11:12

four for the ams 24 to get the best

play11:15

performance okay let's hop over to the

play11:17

headphone output i will not bore you

play11:19

with all the details you can see all the

play11:21

numbers and colors indicating the

play11:23

performance on screen generally speaking

play11:25

the headphone outputs are okay although

play11:28

the ams24 is the clear winner here

play11:30

especially when it comes to noise with

play11:32

the ams22 you might start to hear some

play11:35

noise with more sensitive headphones and

play11:37

with in-ear monitors you will clearly

play11:39

hear constant background hiss on the ams

play11:42

24 i didn't hear obvious noise with iems

play11:44

and with normal over ear headphones it

play11:46

is unlikely that he will hear any noise

play11:48

the ams-24 also could drive headphones

play11:51

to a louder listening level and the

play11:53

frequency response was considerably

play11:55

flatter because of all these reasons i

play11:57

much preferred the headphone output on

play11:58

the ams 24. distortion performance is

play12:01

very comparable though and actually low

play12:03

enough to not waste any further thoughts

play12:05

on it quick notes on the rzo driver you

play12:08

have a drop down to select your

play12:09

different sample rates and a slider for

play12:12

your buffer size that's it nothing else

play12:15

this is pretty much as bare bones as it

play12:16

gets i checked the latencies and

play12:18

comparatively speaking they are a bit on

play12:20

the longer side the very lowest buffer

play12:22

settings also seem to not lower the

play12:24

latency by that much more so you are

play12:27

probably best off using the second or

play12:29

third lowest buffer size when latency is

play12:31

important for you other than that the

play12:33

measured times are relatively close to

play12:35

what was reported by the driver which is

play12:37

always good to see so what do i think

play12:40

about the zoom ams 22 and 24

play12:43

i think they are okay although in this

play12:45

day and age i do expect a bit better

play12:47

performance from an audi interface my

play12:49

biggest gripe is the comparatively high

play12:51

preamp noise if you use condenser mics

play12:53

this is really not an issue but if you

play12:55

use dynamic mics especially low

play12:57

sensitive ones there's a good chance

play12:59

that you will hear some audible noise in

play13:01

your recordings these days there is

play13:03

really no good reason anymore to have

play13:05

such high noise preamps

play13:07

shame on yuzu while it was already quite

play13:09

critical about the presonus audiobox go

play13:12

in its review compared to the ams 22 i

play13:15

think it's actually a better buy here

play13:17

especially if you can live with a bigger

play13:19

form factor things might get a bit more

play13:21

even if there is a firmware update that

play13:23

lets you directly power the ams 22 from

play13:25

a phone but even then the ams22 has a

play13:28

higher noise headphone output which is

play13:31

quite obvious with a sensitive

play13:32

headphones and the preamp noise is also

play13:35

noticeably worse compared to the

play13:36

audiobox go when it comes to the ams24

play13:39

in my opinion it's a much more

play13:41

compelling option for portable recording

play13:44

as it usually works with a singular usb

play13:46

connection to a phone it also has the

play13:48

option to be powered with double a

play13:50

batteries or if you need a power bank

play13:53

you also get the two xlr and trs combo

play13:56

inputs two headphone outputs the option

play13:58

to quickly switch between music and

play14:00

streaming mode and all that in a still

play14:02

very portable package alright please

play14:05

give this video a big thumbs up if you

play14:06

enjoyed it subscribe for more reviews
