- Hi, I'm Jordan from Kettner Creative.
In this video, we're gonna test to see whether the outputs
on the Behringer Xenyx Q1202USB audio console
are balanced or unbalanced.
In two previous videos that we've done
we claimed that they were unbalanced.
In the manual here, we have the Q1202 USB manual
that came with the console.
And when you open it up to the English page,
you can see the phones and control room,
the unbalanced control room jacks
that carry the sound effects , et cetera.
And under main mix, you can see unbalanced mono jacks.
So that's where we got that information from
it's from the official information from Behringer itself,
but, we did some more testing and I think that is wrong,
so to confirm that test, what we have here
is we have a TRS to XLR adapter cable,
and we're gonna run the outputs of this console
through 300 feet of XLR cable into this powered speaker.
As we all know, unbalanced audio will tend to degrade
extremely quickly, somewhere between 15 and 20 feet,
it'll pick up electrical interference, hum, hiss,
and just a whole bunch of ground noise,
ahhh so we're gonna test if it can make it through 300 feet
without a lot of that noise,
then we know that these jacks are in fact balanced.
So to do that experiment, we are gonna connect this
lightning to headphone jack adapter
to the bottom of my iPhone.
We're gonna take that headphone output
and connect it to an eighth inch to dual quarter-inch cable.
And we're gonna plug that into 1112 on this audio console.
Next we're gonna connect our TRS quarter-inch
to balanced XLR adapter cable here.
Now this cable will not balance a signal, but it will work
if the signal's already balanced from the console.
In order to balance the signal,
you'd have to run it through a transformer,
something like a DI box,
which we're not gonna do in this video.
So we can do an accurate test.
Next, I'm gonna plug that into the cable here.
All three of these 100 foot XLR cables
are already connected to each other, making a 300 foot run
into the back of the speaker.
So I'm gonna turn the speaker on,
turn all my outputs down.
I'm gonna hit play on some music here,
bring the main fader up to zero.
Gonna increase channels 9 and 10 here
and turn up the speaker,
the volume on the back of the speaker here.
So we can see here we are getting good clean signal,
I'm not hearing a ton of noise.
I hear the fan on the back of the speaker,
just cause I'm standing right beside it,
but I'm not hearing any signal degradation
or anything like that coming out on the speaker.
So I'm pretty confident that the main outputs are balanced.
Next thing I'm gonna turn that down,
turn the back of the speaker down
and we're gonna try the control room outputs.
We're gonna turn up the back of the speaker.
We're gonna bring the main fader up to zero
turn the level on the 9 or 11, 12 up to zero
bring it up.
So again, we're hearing the signal.
It sounds pretty clean to me
I'm not hearing what would be typical of
an unbalanced signal going through 300 feet of XLR.
So I'm gonna turn all that down
and now we're gonna try the effect send,
should turn the speaker down there,
but that's okay. So the effect send is up at unity.
We're gonna try this.

So again,
I'm pretty confident that all three outputs on this audio
console are balanced,
I'm not hearing that noise or static or hum or hiss or any
interference or anything like that,
that would be common with an unbalanced signal.
So I can conclude here that the I'm sorry that I gave bad
information in the previous two videos,
we did just go off of what the manual said without testing
it, but we're not going to go back and refilm those videos
because it is straight from the manufacturer where we got
that information.
So we will put this correction out.
We'll link it to those videos, and then, yeah,
we'll go from there.
So if you have any questions about this,
or if you think that this test is wrong in any way,
please let us know in the comment section below.
