Hello all and thanks to the many contributors who've taken time to post on these forums. I've been lurking and soaking it all in like a sponge, but now I have a question that I haven't been able to find an answer for via my friend Google:

Will phantom power harm my Sony URX-P1 tuner?

I would like to connect it to my Marantz PMD661. I have phantom power on to power my AT 4053b and would like to connect my ancient Sony UWP as a backup. But I can't tell if phantom power through the XLR-BMP cable will harm the tuner/reciever.
 
Why not just turn off phantom power when the tuner is plugged in? You can't transmit phantom power wirelessly or maybe I'm misunderstanding.
 
I should have been more clear in my initial post: I will have both the AT4053b and the UWP connected at the same time. The AT4053b requires phantom power. The PMD661 supplies power to both mics or neither - I can't have phantom on for one but not the other.
 
If the UWP is balanced and the output is mic level, it could be OK. If unbalanced, it could damage the receiver and/or the recorder. For instance, the Sennheiser G2/3 and some Lectros will rapidly drain the batteries on my SD mixer with the channel's PP enabled. (been there done that) No damage occurred though. To be safe, get an external Phantom Pwr. supply or an ISO transformer or filter that does not pass PP.
 
To play it safe you could stick an isolation transformer on the XLR Or a Phantom Power Blocker

The two risks to not doing that (unless the documentation says otherwise) is that yes Phantom could cause problems with the receiver (tuner is usually used to describe a home stereo component, though the two are doing basically the same thing).

The second is if the receiver is not putting out a balanced signal it could be just shorting the unused pin to ground and that could cause problems for the phantom power section of your recorder. As in burn it out. It should be protected from shorts but?

As a general rule you want to block Phantom (or turn it off) for any mic that doesn't need it. Most balanced mics will just ignore it but a number of factors could cause damage even to mics that "should" not have a problem.
 
Thanks very much guys! I will go with plan A.

I know "tuner" sounds funny in this context, but that is how Sony refers to it in the documentation.

Very much appreciate the advice!
