Re: Sony DMX-P01 mixer & Zaxcom

Hi Marty
I've tried all number of things, including ferrite beads, I had a cable made up by a Tech at Panavision that had some kind of filter in it...no go, I'm just about to make a DC - DC convertor to give clean power from the Hawks Wood box,
That, I am reliably informed, should solve the problem.
Time is the key....

Martin,
Have you tried filtering the power supply leads to the Zaxcom (hot & ground) with either capacitors, ferrite beads or both?

Hi there.
AFAIK, there is no supplied camera snake supplied with the machine, just the male plug that attaches to the mixer.
I had one made up and therefor have a breakaway system.
I have been powering a Micron Tx as a camera link untill reecently, when I got my Zaxcom stereoline.
Until then it was fine, but will only power a tx when it is externally powered, (NP1 etc).
Since I have gotten my Zax system, I've had no end of problems with high frequency noise being picked up by the Zax transmitter, and consequently sending to the receiver.
It appears that the Zax and the Sony don't like having the same earth.
When the tx is self powered, (AA's), all seems well, but even when it's powered from a Hawkes Wood power distro, the noise returns.
It's had the Zax tech here in Australia baffled.
Seems the only solution is to filter the power through a DC to DC convertor, (which I'm yet to try), and hope that fixes the problem.
I don't seem to have the same problem when I use my shure mixer,
I didn't need to take the unit to Sony for service, in fact they said to take it to a Sony dealer, who happens to be the one I bought it from.
All in all it's a good mixer, and I find the limiting / compressing features invaluable, especially on the inputs, and also the camera check function which reads the output from the camera when cabled up and analyses the signal for conectivity and phase....

You wont go wrong

Thanks for the input.

Martin - Is finding service a problem? Does it have to go back to Sony
- please say no........

Does the camera snake that comes with the mixer a breakaway type - the
literature makes it seem like it isn't - or have you had a custom
snake made? Are you powering any wireless from the mixer? I would most
likely want to use a Lectro 'Y' to two receivers, to start. Maybe a
BDS setup later - to add a couple of transmitters.

Thanks again.
