Hi all,
Today was the first time I tried the Ventus Headphone Amp with serious headphones.
I tried several but they seem to overboost.
With the volume at approx. 50% no loud sound is comming out but it seems quite ok.
If I increase the volume a little bit it makes a sound like the recording was over squelched or something like that.
I did not installed the CC2 and CC3 Caps.
Before I go to troubleshooting and dismantling evrything; Can someone say something about this?
Thanks in advance!
Jordo

I checked the connections and they are all ok. I also added CC2 and CC3 to the boards. Still this makes no difference. The sound is overboosted certainly at more than 50% volume. And the channels left and right keep swapping on and off. Again more with the volume above 50%. Does someone have a proper hookup sceme for the ventus EZ? Does the IN- and the ground need to be jumped just like the Ventus? Since the headphone jack only got one ground, do they share the same ground? I now connected the grounds together on the jack and they go back to each seperate Ventus... I'm not sure if I'm doing it right here....

Ok, I just used some normal wires, no shielded cables and no twisted pairs.
There is a 'hum' to be heard and also some crackling sound but it certainly improved.
