    Hi,
    Is there any way to reamp recorded voice through the pedal?
    I’ve been trying to do it but no success… Vocoder seems to be working only when I’m conecting Microphone. I tried to do it with the jack – xlr cable (jack in output of my soundcard, xlr to MIC input on V256) and it doesn’t seems it receive any signal..
    Thanks in advance for the help.

    Hi,
    I’d like to do this too but like you, had no luck. I ended up getting a TC Helicon Voicelive Rack which had an instructional video on how to set it up for this ( pre recorded voice track put through it as opposed to live singing ) It has something to do with gain staging from memory. Having seen the video I think it should be possible with the v256 too. Some help with this would be great as it would open up a whole new dimension of creative recording possibilities in the studio.

    This should definitely work. What soundcard are you using?

    Hi, I’m using UAD Apollo Twin,
    I got reply to my email from ehx, but I’m not sure that I understood what to do.
    Here is the reply:
    “That’s a bit bizarre. It is a balanced input so if the signal is applied to both phases, you will get nothing. I would have a look at the wiring of the cable. As you are using an unbalanced input, the signal needs to go to only one phase. As it is a mic input, it will also need a pretty low level, like maybe 200mV p/p.

    I can’t see why this wouldn’t work.”

    Should I use balanced or unbalanced cable?

    & I’ve got a RME UCX. You’d use an XLR cable going from one of your outputs on your interface into this & out of the v256 into one of your inputs. I just worry I might blow something up. The XLR input of the v256 is 10 kilo ohms. So…your output would have to be in the acceptable range…I think..(line level?) …’what the hell’s a jigawatt!?’ It’s this gain staging thing again. :P

    I just read in the manual that the v256 is 24 bit 36 kHz..maybe the recording would have to match this? As opposed to 44.1 or 48 etc?

    It is best to give the MIC IN connector on the V256 a balanced signal.

    On the UAD Apollo are Line Outputs 3 & 4 balanced? Assuming they are, use a balanced cable with 1/4″ TRS on one end and male XLR on the other end. The TRS plug goes into Line Output 3 on the Apollo, the male XLR end connects to the V256 MIC IN.

    You do not need to match sample rates in this case because the V256 inputs are analog only. The signal from the audio interface needs to be analog. It does not matter if the sample rates do not match between the V256 and the audio interface.

    It is important to think about sample rate when you send digital audio over cables, from one unit to another, but sample rate is not a factor when sending analog signals between units.

    Yes, use a balanced line output from your audio interface. 10K load is pretty standard to put on a line signal.

    It works!!! sorry I was so stupid I didn’t change setting from Line in to Mic on my apollo input, once I did it, its working, just sound is quite distorted need to experiment with levels I think. Thanks for your help!

    Yes you do need to reduce the signal level into the V256, once you do that it should work fine.
