I understand the jack size difference. Your MB jack is 3.5mm, the headphone |
17 |
jack on the Behringer is 1/4". All the headphones I've purchased for years |
18 |
came with an adapter to plug into 1/4" jack but if your didn't they can be |
19 |
purchased at Amazon or general stereo/TV type stores. (Best Buy as an |
20 |
example in the U.S.) Search for "3.5mm to 1/4 adapter". |
21 |
|
22 |
I'll explain the headphone monitor function in a moment. You are correct |
23 |
that the headphone jack on the Behringer has nothing to do with the |
24 |
headphone jack on the computer. The Behringer is a complete sound card with |
25 |
2 inputs and 2 output at the end of a USB cable. It has phono jack outputs |
26 |
on the back which would allow you to hook it to your stereo inputs to hear |
27 |
computer audio. In that sense it's no different than a CD player or tape |
28 |
deck. To use the outputs on the back would simply come down to telling |
29 |
Linux I want to use the Behringer USB device as my sound card and all sound |
30 |
would be router there. Once the audio is correctly going to your stereo you |
31 |
should also hear the audio over the headphone jack. |
32 |
|
33 |
The monitor function associated with the headphones is different on cards |
34 |
like this. Notice that the switch says "Direct Monitor". Imagine that I am |
35 |
recording a song. I already have some of it recorded, say drums, bass and |
36 |
piano. Now I want to record vocals so (wearing headphones so I can hear |
37 |
what I'm supposed to sing along with) I sing into the microphone but there |
38 |
is latency in the system. The vocal gets converted to digital by an |
39 |
internal A/D converter, sent down the USB cable, routed to the recording |
40 |
application - in Linux lets say that's Ardour. Ardour records it onto disk |
41 |
but it also sends my vocal back to the Behringer so I hear myself in the |
42 |
headphones. The probably is that my vocal is delayed by 25mS or more. It |
43 |
sounds out of time and I'm confused. It sounds like an echo. |
44 |
|
45 |
Look at the diagram here to see what I'm trying to explain: |
46 |
|

48 |
|
49 |
Direct monitoring changes the signal path in the picture on the Ardour |
50 |
page. It still sends my vocal down the USB cable and Ardour still records |
51 |
it but it __ALSO__ sends my vocal __DIRECTLY__ from the mic to the |
52 |
headphones skipping the whole digital path in the picture. There is no |
53 |
delay. I hear myself in time with the music. It feels natural and I perform |
54 |
my part of the song brilliantly and go on to make millions of dollars. |
55 |
(Well, maybe...) |
56 |
|
57 |
Direct monitoring probably won't matter i your application because the |
58 |
real-time nature of what you're speaking won't be effected very much and |
59 |
probably discord or zoom won't send it back out to the card, but only send |
60 |
it to the people you are meeting with. |

Hope this helps, |
