welcome to my unboxing and first look at the ASUS Zonar Essence
0:11
STX now I talk about sound cards a lot
0:15
and people ask me for sound card recommendations a lot and you know
0:18
there's sort of lower-end ones the whole Zone R line actually is just kind of
0:21
awesome so whatever your price range is just buy a Zonar and you'll be fine um
0:26
but this one is like the baller Zonar
0:30
this is the Zonar with all the features that you need especially if you use
0:35
headphones so 124 DB sound to noise
0:39
ratio which is just ridiculous I mean remember that decb are essentially a
0:45
doubling of of in terms of sound to noise ratio it's a doubling of quality
0:49
every time you go up 3 DB okay so think
0:52
remember that so when you see something that's 110 DB sound to noise ratio that
0:56
is like many times worse than this okay
1:00
it has swappable opamps which means you can actually customize the sound of it
1:05
according to your liking so if you don't know what opamps are those are the uh
1:10
the components on the board that actually do the amplification for the
1:14
card okay so we're going to go ahead and start opening this up the reason I'm
1:18
opening this is cuz we're using it in like an ultimate system build guide so
1:21
if I was picking an ultimate sound card for me personally this is the one that I
1:25
would choose let's have a look at what ASUS has to say for themselves on the
1:29
box here anyway though so industry leading okay with basically no
1:33
Distortion built-in headphone amp provides exceptional quality even with
1:37
600 ohms of impedance remember guys for context a Sennheiser hd800 is 600 ohms
1:43
of impedance so we're talking like spending well over a grand on headphones
1:48
before you're going to run into the limits of what this can drive okay
1:53
nickon fine gold capacitors offer great Dynamic performance it uses audio
1:57
capacitors which are actually different from the kinds of capacitors that some
2:02
competing products are using on sound products whether it's built into a
2:05
motherboard or whether it's built into a sound card where they're more like
2:08
motherboard capacitors different capacitors will affect the way the sound
2:13
comes out of the analog signal like remember guys okay any of the music
2:18
you're listening to is inherently digital any of the sound you listen to
2:22
is inherently analog so the process of
2:26
converting that digital signal to an analog sound is extremely complicated
2:31
and depends on every aspect of the design of the card so everything from
2:36
the processor to the Dax so that's the digital to analog converter everything
2:41
to the do they have anything on here about the Emi shielding okay well Emi
2:45
shielding to keep just random interference that's bouncing around
2:49
inside your PC from from affecting any part of that process to the uh to the op
2:55
amps as well everything affects the process so okay moving right along
2:59
perfectly Shield Emi free okay there it is uh customize your sound card
3:02
effortlessly with swappable app opam sockets you can just buy them online
3:06
it's not a big deal uh okay in terms of driver features they'll be digital live
3:09
D be headphone D be virtual speaker they'll be Pro logic 2 direct sound 3D
3:13
vocal effect smart volume acoustic Echo oh acoustic Echo cancellation that's
3:17
kind of neat okay and let's go ahead and check out the card itself so they have
3:22
like an awesome picture of the card which we'll use to help us through the
3:27
process oh yeah so guys if you if you
3:30
don't know I'm running um an ASUS uh s
3:35
what am I running I'm running a Zonar zent which is a similar card to this one
3:40
but actually not quite as good if I was going to pick my ultimate sound card
3:44
this one would be it so in terms of IO you've got stereo outputs so front right
3:49
front left this is if you're using an external amplifier so for for Amplified
3:54
speakers or something like that then you've got your amped headphone jack
3:58
your line in and your spit this is your digital out so this is a headphone
4:03
lovers sound card this is not for you
4:06
know 7.1 or you know whatever sort of
4:09
things that people think are fancy this is for audio files who are interested in
4:13
stereo speakers high quality output to stereo speakers or high quality output
4:18
to headphones it does have front panel Jacks so you can still plug in your
4:22
front panel headphone jack and microphone Jack but honestly guys if
4:25
you're not using these ports you're doing it wrong with a sound card like
4:29
this has a dedicated Molex power adapter
4:32
or connector rather and that is because this card actually does draw some power
4:37
in order to deliver that Punchy sound at a moment's notice it also has some very
4:40
large caps going on which is going to help with that as well you can see that
4:44
while this sort of shield on here this Emi Shield looks like it has gaps in it
4:48
there's only very small gaps so from the inside of the case there's almost no way
4:52
for any kind of interference to get in there you can see it's actually blocked there's a copper piece that's right in
4:57
there that makes it so that nothing can really sort of get in there it uses PCI
5:01
or rather PCI Express 1X connectivity remember guys that can be plugged into
5:06
any PCI Express slot whether it's 1X 4X 8X or 16x PCI E1 pcie2 pcie3 all of
5:13
those standards are are basically interchangeable for the purposes of
5:17
something like a sound card here's an adapter so you can take those analog
5:21
outputs and you can run them to just sort of a regular stereo Jack okay
5:25
here's an adapter for this so you can run uh smaller jack headphones or
5:30
microphone off of this all right and then there is a oh awesome I actually
5:36
didn't realize this but this coax Jack right here is actually Optical as well
5:40
so you just use the included adapter and you can get an uh you can do optical
5:44
audio out from there too all right included documentation audio Precision
5:48
test report your individual sound card
5:52
was actually tested and this was printed out from your sound card so this will
5:56
give you the full characteristics of your card this card that's in the Box as
6:02
opposed to being some kind of generic you know how a lot of high-end products
6:06
come with like a certificate of performance or something like that that
6:09
actually has no basis on this thing this
6:13
physical object that's in the Box not how it works with an Essence STX this is
6:17
a serious sound card all right we got a thing about the
6:21
philosophy of something in a picture of the card okay that I'm less interested
6:25
in moving right along we've got uh ASUS's driver disc don't use this
6:30
download the latest off Theus website they're excellent also there's a third
6:33
party um Universal driver for Zonar
6:36
cards that actually has a couple of extra features so that's kind of cool
6:39
here's a sticker that you could put on something okay uh here's a quick start
6:44
guide here's a wow there's there's a lot of documentation here slick there's
6:47
another quick start guide I told you there's two quick start guides are these
6:51
the same thing oh no they have different part numbers on them okay and then
6:54
there's uh like another poster they have two posters included
6:59
yep okay all right
7:03
cool um I think that pretty much covers
7:06
it so if you're looking for a sound card recommendation my general recommendation
7:11
is some kind of Zonar card if you're looking for a specific recommendation I
7:16
would take this one personally um I'm more of a headphone guy I don't use
7:20
surround so that's that's the context of that recommendation from me but uh let's
7:25
just see if we're missing anything here hyper grounding circuitry design okay oh
7:29
I don't know if I mentioned but it uses a bur Brown PCM 1792 a digital analog
7:34
converter so that's part of achieving that 124 DB single noise ratio this one
7:39
can do even better than that swappable op amps perfectly sealed analog output
7:44
path with all that shielding and all of that good stuff and I think that pretty
7:50
much covers it thank you for checking out my unboxing and first look at the
