[Jack Lam] “2) By design of the HPX170, the headphone circuit only shows me a live signal as opposed to a recorded signal. The signal chain to the P2 recording are processed differently than what I heard, and it is these processing that was at fault.”
You choose which one you want to listen to, if you monitor the recorded there will be a delay but that is normally what would be expected.
Without posting a segment of the issue there is no way of knowing.
BUT here is one thing, the HVX and HPX always record the camera mic. So if the producer is not turning off the camera mic he is listening to a mix of the built in Mic and the Lav, which would sound like crap. If you have a external mic you will not hear the camera mic through the headphones. Hopefully this is the problem.
