Re: Sony PXW-X70 announced: Pro XDCAM version of AX100

Thanks. Certainly switching Ch2 to Line (and adding the 20dB attenuation) makes the hiss and crackle so inaudible as not to be a problem - but the issue occurs whether there's something plugged into one or both XLR inputs. So, even with a mic in each input, the noise occurs. And the source, I've found after much testing, is definitely Ch2. The settings of Ch1 makes no difference but Ch2 is making the horrid noise that affects both channels, rather like listening to someone tuning in a Longwave radio at midnight... I imagine I must have a broken handle unit, it is a Sony review sample after all and it's probably been through the mill with other testers (though I'd have hoped it would withstand the abuse) Still no idea what the beeping is mind you, the testing continues... Regards David

Re: Sony PXW-X70 announced: Pro XDCAM version of AX100
Ahem:
It stops as soon as I stop recording despite continuing to monitor on the headphones with no changes to the mics etc. Press record and it starts again.

Crikey - I keep both the inputs on my PMW-200 to Mic+48 even with only one plugged in and no probs, so must be camera dependent. Anyway, regarding the X70 I had mics in both inputs and it still happens. Neither was touching the camcorder itself. I would honestly be delighted to be shown that I'm doing something stupid but I'm sure it shouldn't be like this esp when Ch1 is clean regardless Here's a quick video to demonstrate:

Re: Sony PXW-X70 announced: Pro XDCAM version of AX100
In my case the NX30U, a detachable units like the X70 ( of course could be the same unit repackaged) is worse than the AX1 or the NX5U but all have similar characteristics. Do the mics need the same gain trim in the menu ? Does altering the gain trim make any difference ?
Not sure how channel 2 causes this issue but I either have both inputs selected with mic on channel 1 ( channel 1 auto and 2 Manual gain with the XLR selection on channel 2 set to line no input) or with inputs mic on channel 1 and line on channel 2 ) and with this configuration there is no noise. Sort of makes having a mic input on channel 2 a little useless !!! But that is how I set up most of the time. Ron Evans |

David and Ron:
This thread is huge, so I apologize if you have already covered this. Have both of you done the firmware update? |

David and Ron:
If the audio issue does not get resolved soon, will either of you regret purchasing this particular camcorder? I have a pressing interest in knowing. Thanks! |

Re: Sony PXW-X70 announced: Pro XDCAM version of AX100
Withh regards to David's first video above titled "Sony PXW X70 audio beeping", I've isolated out the beeping.
First thing to note (forgive the pun) is that there are two tones at work, on the 1khz and 2kz frequencies. A visual spectrogram of the cleaned up-ish audio is attached. You can download a finished .wav sample file from http://www.filedropper.com/pxw-x70beeps Andrew PS. It really does sound like a heart beat monitor for your camera. At least, that's what came to mind. |

Having said that, I thought the audio fix in the firmware was simply something to do with swapping the channels round? I reiterate that as a loan unit, it may simply be that mine has been damaged by careless reviewers prior to it getting into my sticky paws. In answer to your other question though, if I *had* purchased this, I'd be pretty annoyed by the audio glitches if they proved not to be a faulty unit but inherent. Regards David

Also, does anyone know if the Wi-Fi capability on the camcorder allows for you to control zoom via the app? There is no users manual online for the Sony PXW-X70 and I am surprised at the lack of updates on Sony's behalf of firmware and documentation. |

Re: Sony PXW-X70 announced: Pro XDCAM version of AX100
...and I have a basic Libec unit - would it also require these same two cables??

Re: Sony PXW-X70 announced: Pro XDCAM version of AX100
Those two cables work with my Libec controller just fine

I think I would be suspicious of the unit you have in hand. Maybe there is an issue with the handle unit. If you remove the handle unit can you still record this phantom beep? If so then that would suggest an issue with the camera itself. Chris Young CYV Productions Sydney |

Re: Sony PXW-X70 announced: Pro XDCAM version of AX100
That's very reassuring to hear and thank you for that extensive testing.
Sony are now sending me a replacement loaner so I'll post an update here when it arrives. Apparently the dodgy-sounding X70 was taken to Africa by a journalist before me so it may have been nibbled on by a lion or something... Regards David
