today I have another ASUS oxar rather Zonar product to unbox this is the
0:11
mobile headphone amp USB sound card so ASUS's claim is that this can power up
0:16
to 150 ohm headphones which should
0:21
basically cover anything out there as
0:24
far as gaming headsets go so this is a
0:27
gaming oriented product and they are saying that can pretty much power any
0:31
gaming headphones and it is a great replacement for onboard notebook audio
0:37
so there is the USB device itself you know what let's go ahead and get it open
0:40
up here and then we will talk about it in a little bit more detail actually you
0:44
know what no let's do the back first okay audio chipset is uh proprietary
0:49
ASUS one it uses USB 2 okay out look features has an LED
0:56
indicator play music and idle LED on mute is Led off
1:00
okay cool operating systems Windows 7 and vist and XP Dolby Technologies
1:05
including Dolby headphone Dolby virtual speaker Dolby prologics and Dolby
1:09
Digital live so Dolby headphone means that you can use this sound card in
1:14
order to power your regular stereo headphones in Virtual surround okay so
1:19
that's a sort of a preference thing whether you like it or not but you'll
1:22
have the option analog output Jack and
1:25
digital spiff output combo so it has a 3 and2 mm mini analog and digital combo
1:31
Jack cool built-in headphone amp with up
1:34
to 98 DB sound to noise ratio signal to noise ratio sorry I always say sound to
1:39
noise ratio but I know it's not right okay for 32
1:45
ohms cool okay so you actually have
1:49
three different gains that you can select in the software so you can tweak
1:52
it depending on what kind of impedance the headphones you're using happen to be
1:56
analog input jack is a mic in okay so you can use this for your microphone as
2:00
well as for your headphones okay driver features you can just sort of look at
2:05
that you guys can pause if you really want to read that okay actually no some of these are
2:09
important so the 3D yep normalizes the volume smart volume normalizer k Magic
2:14
voice that's kind of neat modifies the sound of your voice for VoIP and online chat
2:18
applications hello I'm Linus okay that's
2:21
not very good but whatever gx2.5 enables the latest eax audio so that's eax
2:27
5.0 and audio performance so there's your audio performance specs right there
2:33
what else we got here system requirements really 256 Megs of RAM Al I
2:37
can't run this on like my uh my Pentium one okay package contents okay what else
2:41
we got here some not English headphone amplifier so extra base punches and
2:46
sound details by fine tune headphone amp circuit okay whatever that
2:51
means what they're trying to say is that using a headphone amp even a small USB
2:57
powered one like this and using a a sound card even a USB one like this is
3:03
going to be worlds better than whatever you're using on your notebook now the
3:07
exception might be notebooks that actually have high-end onboard sound
3:12
although those are few and far between I
3:16
have been an advocate for a very long time of using Sound Solutions that
3:21
aren't total totally horrible so the
3:24
Zonar u3 aims to achieve that on the
3:27
notebook side I would not necessarily recommend using this on a desktop
3:30
because that is not the intended purpose but for a notebook you can expect to
3:34
have a significantly better experience so you can output to a variety of
3:38
different things including look at this you can output SPI if out to uh an
3:42
amplifier or rather a receiver you can connect headphones and microphone you
3:47
can connect a line in audio source and you can configure what all of
3:52
these are doing through the driver we also have included a USB extension cable
3:57
so this is going to allow you to not plug it directly into your notebook say
4:01
you have a notebook that doesn't have um enough space around the USB port so you
4:05
got other things plugged in you can't fit sort of a bulky connector like this
4:09
well you can use the extension cable to just run it a little ways away so let's
4:13
have a look at the u3 itself it's fairly straightforward I
4:17
think there we go it's got two things on
4:20
the top that look like speakers but they're not okay it's got a cap which
4:25
stays connected which is kind of handy because you don't want to lose it okay
4:28
it's got a split ring keychain attacher thing here so in
4:34
theory that will also help you to not lose it there are is your headphone jack
4:39
as well as your microphone
4:42
jack hold on just a moment so what makes this better than
4:47
your onboard audio in all likelihood your onboard board audio is using an
4:50
inferior audio chipset because that's one of the specs that Joe average
4:54
consumer doesn't care about when he's shopping for a notebook so they tend to
4:57
cheap out on it uh the other reason is that it is separated from the rest of
5:01
the components that are inside your notebook so there's all kinds of fan spinning and electrons moving around and
5:07
high frequency switching going on that causes all kinds of absolute havoc on
5:12
audio equipment which is designed to operate best we want designed to operate
5:16
best but is limited to operating best when there are very few sources of
5:20
interference so I would say you're going to get the best performance out of it when you actually take it and plug it
5:24
into this and get it as far away from your notebook as possible one of the
5:27
other reasons is they use what they're calling X grounding in order to reduce
5:33
even further the interference that can be caused by the PCB design itself so
5:39
that's good as well one last thing I wanted to also mention actually this is
5:42
on my deck here you know you don't have to look at that so there's three different modes there's viip mode
5:46
there's gaming mode and there's excite mode and basically those are just you
5:49
know zero boost to the noise Audio Level
5:53
then there's a 9 D boost which also includes amplifying some of those higher
5:57
range sounds you know the the footsteps for U FPS Gamers and then
6:03
finally the excite mode I think is more for viewing videos so it's a little bit
6:06
louder so and is great for you know explosions and all that kind of good
6:10
stuff so thank you for checking out the unboxing video of The Zone ru3 don't
