VersaPort Question
VersaPort Question Posted on: 23.06.2013 by Inge Rechtien Hello,I own one American Audio VersaPort, my question is can I cue with my headphones connected directly to the headphone jacked from the audio interface? I was trying yo use it with mixxx and traktor, but in both i can only set the outputs to example: Main 1/2 Monitor 3/4 But the audio that comes from the headphones is the main, I hear both songs. Is it possible to set the headphone output to work as 3/4? I have the American Audio VersaPort ASIO drivers installed. Any solution? Thanks in advance. | |

I have also observed the loading effect via oscilloscope of connecting a low impedance device like a cheap pair of headphones to a line output port. A regular Line Out is not supposed to supply any current at all (ideally); the ideal op-amp has infinite input impedance it draws no current from the input device. Which is precisely the point of the operational amplifier (within a Line Input) - to produce an output signal without drawing current (loading) from the previous components.
A line input has a typical impedance of 10kΩ - compare that to the impedance of typical headphones. Headphones will draw a huge amount of current vs a line connection, and may end up damaging components due to the current draw. |

Each stereo output has an integrated headphone amp that engages automatically if a headphone is inserted (via impedance detection). Otherwise, it works as a regular line output.

| Inge Rechtien 01.08.2013 | Hello, I actually bought that cable, and now I'm using traktor pro 2.6.3. In the output section it only shows output port 1/2, I can't get a proper configuration to be able to cue. I have the asio driver from Versaport. Any one? Any suggestions? Regards

You could buy one of these: !BrhFH7gBmk~$(KGrHqIH-C4EvCWUTyvdBL0BQyTvvw~~_12.jpg and have either 1/2 or 3/4 as your headphone out... |

| Alphonso Deitchman 01.08.2013 | Headphone amplifiers exist for a reason. Line outputs should only be connected to high-impedance line inputs. |
| Brunilda Kora 01.08.2013 | Rubbish. |
| Alphonso Deitchman 01.08.2013 | Don't use one of those adapters to connect headphones into RCA sockets. They are not suitable for driving headphones and are only designed to transmit a line level signal to the next piece of gear e.g. powered speakers or an amplifier. |
