add some additional headphone outputs or maybe get a little more power to your
headphones in this video I'm unboxing and testing out the behringer micro amp
Behringer MicroAmp ha400 microphone amplifier I'm Zane and on this channel I do
weekly audio tech tips tutorials and reviews to help you conquer the tech and unleash your
creativity and links to the behringer microamp ha400 headphone amplifier
plus any other gear I mentioned in this video will be in the description now
let's jump in all right so here's what came inside the box we've got the
behringer micro amp ha400
the power cable which is nice and small and a couple of pieces of information
I'm sure ones warranty info and the other ones probably installation I'll
look at that later so my initial thoughts of this are it's actually built
quite strong it's built of a solid metal which is nice and the knobs actually
feel really nice and tight they're not really loose or anything like that feels
like a very solid piece of gear but now let's connect this alright so I have it
plugged in as you can see the LED light is on there and that made me notice that
there is no on/off switch for this so if you want to power it down when you're
not using it you do have to unplug it now for connecting it to your audio
interface you want to get a cable kind of like this one here it's a balanced
TRS cable you can see it has the two little lines here this is going to give
you a nice clean stereo sound if you just use an instrument cable like a
guitar cable you're only going to get a mono signal going into your headphone
amplifier and a cable like this one will give you that stereo signal that you
want I've included a link to this one it was fairly affordable on Amazon but you
can use any balance TRS cable out there so one end goes in here the other end
goes to the headphone out of your audio interface if you want to turn the volume
up to around halfway maybe a little over half on your audio interface to give it
a nice clean signal but you don't want to go too loud on your interface or
things could get noisy now I'm going to test this out with two pairs of studio
headphones I've got the beyerdynamic DT 770 which are 250 ohm headphones they're
actually the reason why I bought this headphone amplifier to give it a little
more power as my focusrite 2i2 just wasn't getting it enough and these are
the behringer hps3000 studio headphones they're very affordable and
there are only 64 ohms so they should be powered by this headphone amplifier the
focusrite 2i2 or anything like that I just want to do a test where I have
two headphones plugged in the first test that I want to do is I'm
going to listen to the dt770s but I'm going to have the volume turned all the
way down and I'm going to turn the volume up on the behringer headphones
that are in the channel right next to it I'm going to see if there's any bleed
into this channel
all right so I turned it all the way up and there was zero bleed through over
into the other set of headphones which is very nice
now the next test I want to do is to see how much volume I need to power my DT
770 headphones so I'm gonna see how much power I need on the headphone amp and
then I'm going to see how much power I need when I'm plugged directly into the
Focusrite 2i2 and what I mean by this is how much power is needed to get a
nice comfortable signal that I can sit and listen and do my mixes with so you
can see this is where it is on the headphone amplifier that's how much
power you need now I'm gonna plug directly into the Focusrite 2i2 and
see how much power is needed from there and just so you know I did crank it up
all the way and it got pretty loud but there wasn't any of that
noise that gives you the ear fatigue like when I do crank the headphones on
my focusrite 2i2 I get some noise in there but these were fairly clean and I
really enjoyed the sound of them so now let's plug in to the Focusrite 2i2 so
here's the amount of volume that was needed on the focusrite 2i2
interface and it is kind of close to where the behringer is but the behringer
was much quieter and I could crank it up even more on the behringer if I really
needed to whereas if I crank it up more on the Focusrite it gets noisier and
it's not as comfortable of a listening experience this is a fairly affordable
headphone amplifier and if you're feeling like you're starving your
headphones and not getting the most of them you might want to add something
like this to your home studio also if you need more than one pair of
headphones connected at the same time the behringer micro amp ha 400 might
