HELP! PROBLEM WITH Sennheiser MKH416 P48

I have sony ex1r with Sennheiser MKH416 but I have discovered that the mic seems not be functioning very well or so it seems to me whenever i tried using it on ex1r (I normally plug it in and switch to phantom power on the camera with switch on channel 1 or 2 put on ext. I have used it once or twice just for testing purposes (i got it like 5weeks ago) but now for no reason to me it will start working and at some other time it will not work and for sometime now I have not been able to make it work. I am suspecting the phantom power either on the camera or the Mic. I tried it on the mixer too without any success, though I am not too sure I know how to use the mixer very well but when I used another mic that does not require phantom power it works directly with the camera and mixer. pls is there anybody with similar experience or am I missing something or I should be thinking of returning the Mic. Your help will be highly appreciated.

Thanks

If you haven't already done so try a different audio cable, most of the time problems like these are cable or operator error (P48 switched off) problems. 416s are extremely reliable mics.

[QUOTE=Juan McFarland;1554050or operator error (P48 switched off) problems. [/QUOTE]


pls what do you mean by '(P48 switched off)' there is no "on and off" switch on the Mic pls can you make more clarification on that and as soon I can get another cable i will test again but the cable I am using was purchased with the mic from B&H Sennheiser Deluxe Shotgun Microphone Kit - B&H Photo Video. but for the sake of testing it again I will get another cable.

Thanks I really appreciate your comments. I still expect that some other guys arround will still try and help.

I have a similar problem.
XLR 1 wont work with dynamic mics, XLR 2 works fine.
its an intermittant fault that I think is with the phantom power.

as a work around you can pick up battery powered inline phantom power modules for around $30

Thanks Gary but do you know of any phantom power module that works with MKH 416. I might be willing to give it a try because it will be very expensive for me to send the Mic back especially if there is nothing wrong with it.

my understanding is phantom power is universal for all XLR mics.
any unit will do, just get something small and battery powered.

My EX1 got dropped and when they fixed it they messed up the phantom power.
problem is I didn't notice until the 3 month repair warrantee was up.
wont be going back there...

I hope your problem is just a simple cable issue. However, I'm not sure how much power the EX1 actually puts out in terms of milliamps. I have to assume that it's giving the full 48v, but you never know. I've been using a Sennheiser MKH60 short shotgun with my EX1 without problems. Just be aware that different mics have different current demands as can be seen with this listing on the Sound Devices site:

I have a 416 and it works fine with the EX1. Do try another cable if you have not done so.

UPDATE HELP! PROBLEM WITH Sennheiser MKH416 P48

I Just bought another rather cheap Mic today as the sennheiser MKH416 P48 continues to fail randomly both with camera and on Mixer the only problem I have now is that the pattern is not repeatable but the new mic works with phantom and battery without any problems though the sound quality is very very low but I need it untill I sought out the problem with MKH 416. Pls what is your advice do I return the mic immediately to either B&H or Sennheiser I am not used to this type of things, I bought the mic as part of a kit from B&H, the other parts of the kits are ok except the mic. your input will be very helpful.thks.

Just trying to eliminate variables....

Does your mic have "P48" printed on the side of it & not "12T" (or something similar?). Just want to be sure your mic is Phantom 48 not T powered.

Fyi, "T" powering is different from Phantom (P) powering. The correct powering must be used with your mic.

Is you mixer set correctly to output P48 power? Some mixers can switch between 12 and 48, namely the Shure FP33.
